Thermal Imaging Gallery
« on: August 12, 2016, 08:48:17 am »
As the title suggest show us your thermal images. Subject can be anything (nature, architecture, electronics...)

At the beginning of the post write some info like this:

Subject: Birds
Camera: Therm-App
Lens: 19mm f/1.0
Image manipulation: stacking/panorama/none/other
Camera mods: ZnSe 100mm lens/pano head

Of course you don't have to write down all the details, but if you do it will be more educational to others.

Interesting -- so on my FLIR images I see horizontal denoise artifacts and it looks like Seek uses verticle denoise?  With FLIR my artifacts almost look like ATSC TV bit errors and were very much more expressed on the F1G1 whereas Seek looks more like interlacing.  Thanks for sharing all the images, c'mon TE for iOS please. :)

Oh, man, I've wanted to do thermography on insects! I wish we could see how the colors on that butterfly correspond to its visible colors, to know how much of this is metabolically-generated heat and how much is absorption from sunlight.

Do you mean i was able to repair it? Yes. a tiny hole... could be filled.
i am quite happy that a guy on a bicycle at the crossroad told me, one side on back was flat.
i drove for round about 30 minutes. Drive feeling was normal, but with windows down and radio off i was able to hear a difference.

I like the stiched panorama a lot.
Almost strange that this is not board support of the FLIR software..


I attached two images made with the CAT S60 phone. ( not mine :-( )

1st is how the guys make fun to all who did not join for drinks.
2nd is my 250 quad in hoover flight. Front and Back props had different pitch, surprisingly this did not make a significant difference in temp of the motors or ESCs.

So the FLIR ONE iOS application allows for panoramic stiching and it appears to use the native iOS stiching method, however, without MSX blending enabled I have been unable to successfully stitch a thermal-only image.

Floor heating using a Flir One G2 iOS.

I also have this video of a board with a short circuit. Two transistors had a bad footprint. Causing a short.


This is what I show people when they ask why I bought this.

People often ask me if i3 T.E. Q1 is good for PCB inspection.
I can only recommend it. :-+ And since it has manual focus you don't need any additional ZnSe lens to get really close:

Had a customer a while back stating the unit was blowing fuses in the disconnect.
initially I didn't even take a thermal image. Due to the condition of L3 fuse just by
looking at it with the naked eye. I told them to call an electrician. An electrician
came out and stated it wasn't the disconnect. The company I was working for didn't
always send back the same tech. After other techs replaced the motor and heating
elements costing the customer well over $4,000 USD. That was just for the work
my company did. The customer stated they were replacing the fuses twice a day at
$10 a piece. About six months later I get a call out there, the issue was never fixed.
Told the customer the same thing. Customer was pissed, and arranged for me to
met the electrician. I met them there one master and one apprentice electrician.
Spent two or three minutes trying to explain the issue with the electrician, with no
luck. Got the thermal camera out. The Apprentice said, "We got to get one of
those". The Master turned to him and said "Callate!". Which is "Shut up" in
Spanish. Then we all agreed what the issue was. After the disconnect was
replaced the customer didn't have any other issues.

On the 30th of January I received my brand new FlirE4 v2.11.
It is still unmodified and I will do the mods in the upcoming days.

The picture below shows the two compressors of an air-drier system.  The right one (hotter) had a fault that kept it always on.

Are those fuses used on telecomm systems 48V DC supply ? I remember seen similar fuses at company telecomm lab (with many 250A rectifiers installed)

Temperature at the centre of the stove is shown as 2147483647 C (exactly 2^31 - 1) or ~2 Giga Celsius (GC). Last time I checked, gas stoves are not known to produce temperatures higher than the Sun and vaporise objects nearby, so software error is likely.

Not sure. Maybe there isn't a big temperature difference from thing? Or maybe they aren't hot enough to radiate a good amount of IR.
A thermal camera requires heat to see things. Much like a visual camera requires light. So I'm guessing low heat=low light in a normal camera. Which gives grainy images. Correct me if I'm wrong.

Therm-App Plus (3rd party app) does, however a lot of the noise is because Bruno is using a f/1.4 lens.

So why is it that the 1.4 lens has so much noise in low temperature differentials withing the photography  frame?

Some comparison between thermapp Opgal app and the ThermAppPlus.

What I realized is that you need to calibrate the noise reduction on the ThermAppPlus  every time you start the app. Otherwise you see no difference.

That makes sense.
You will get best (noiseless) images if you let Them-App run for a few minutes so that sensor reaches it's stable temperature and then do the calibration...

But this is on the ThermAppPlus only. And you need to hold down the button to analyze. It's weird that I have to do it every time I launch the app. It doesn't save the settings.

It wouldn't really make sense to have a "Save" calibration option...
Noise is totaly different 1sec after startup v.s. 5min after startup.

So it's best to do the calibration just a moment before you want to take a noiseless thermal image.
And do it multiple times if you take multiple thermal images. That is if you want a perfection.  ;)

Some thermal modules have a shutter which does the calibration every few seconds...

Ohh ok makes sense now. Yeah then it works well to reduce noise in white hot. Not so much in rainbow. Rainbow works better on the stock Opgal app. Much better colors and smoothness of sharpness in the images from stock Opgal app.

I got PM'ed regarding the usability of the ThermalExpert for piping and leak detection, so here are two images of the floor/roof heating where I live (white/hot with linear scaling).
Temperature difference in the roof is roughly 2K while on the floor it is significantly less due to insulation and wooden floor.

Rightly so, the images are stunning!

I no longer have access to an IR camera, but a few years ago in my previous company, we had one.
One *very hot* August day in South Texas, exactly at noon time, I saw two identical vehicles, but one was white and the other black.

They were parked at the company's parking lot so I ran for the camera.

Took several readings of the vehicle's painted surfaces (avoiding of course the engine bay), and the average white temp was like 49C, and the black one was about 88C.

Made me a believer that, if you live in place with hot summers, one should get light colored vehicles.

I'm regretting buying the FLIR One looking at this resolution.

Software for image stacking (eg Registax, Autostakkert!) and compositing (eg Microsoft Image Composite Editor) means that you can get reasonable results with lower resolution imagers, as I'm sure others have mentioned elsewhere.

Here are some composite images I made with a Seek XR (206 x 156) before I re-homed it.

Apart from the well known issues with noise, sensitivity, linearity and limited actual resolution, the Seek XR performed reasonably well for the price.

Here's an unusual one - a thermal sensor actually scanning. You'll probably have to click the image to see the animated GIF or a higher resolution version of the file on the Flickr site.

This is quite remarkable: I pointed a 25Hz Therm-App camera at the sensor of another Therm-App camera and I could actually see the scanning in progress!

The frame rate of the two cameras differs slightly, which is how come we can see this effect. What you're seeing is the sensor on top of the ROIC (read-out IC) becoming very slightly warmer as each row is read out. This is actually happening 25 times a second but because the two cameras are running at nearly the same frame rate we get a kind of 'stroboscopic' effect, very like the effect you used to see on TV screens being filmed.

There's a decent description of why a filmed TV screen appears to flicker (which works in the same way) here if you want to know more, and the short movie linked from that page shows exactly what's going on.

I found it utterly fascinating to see, and I've never heard of anything similar being filmed before. This is definitely not caused by any other artifact such as a lighting effect or anything physically moving, and when I swapped the cameras round I saw exactly the same effect - but with the motion going in the opposite direction.

Very high resolution stitched panorama of Gibraltar Airport and the Spanish town La Linea de la Concepcion.




This image is nearly 20 megapixels.

I had to fine-tune the jpg compression settings to make it fit the 1MB maximum file limit.

You'll need to download the image to explore it properly: it is well over 9,000 pixels wide. I think it's the most detailed thermal image I've ever made.

Imager: Therm-App Pro (uncooled LWIR 25Hz 640x480 <30mK)
Lens: 35mm f/1.1
Driver software: ThermViewer
Stitched by: Microsoft Image Composite Editor
Tweaked in: Paint Shop Pro

There are a couple of slightly iffy areas in this panorama due to issues with the stitching but overall I'm quite pleased with the result. I hope to be able to make even better-quality images in the future: this capture was done under a certain amount of time pressure and with a slightly flaky imaging setup.

There is a better-than-HD resolution video of the central portion of the image on Flickr.

Also on Flickr is a high resolution panorama of Gibraltar town and the harbour taken from a slightly different location.




The image below is a Barbary macaque (also known as a Barbary Ape, although it's actually a monkey), again made with the Therm-App Pro 35mm F/1.1 and ThermViewer, black hot. I was only a few feet from the animal and struggled with the relatively narrow DOF of the lens at that distance.



There's a close-up thermal portrait of the same animal here and a visible light view from a similar angle here.

whew, those are some nice view for the lens!

I want to request more - using a white hot greyscale palette and locking it. Take a few in rapid succession and stack them in astrophotography software to reduce noise and eventually post process for sharpness.

I am jealous.

@Vipitis, It could be a while before I can do that.  Although I have seen it discussed on this site, I have never tried the image stacking.  I see there are a few such programs for Linux, though; lxnstack, Siril, Gcx...
It might be best to get the lens calibrated into the software first also.

The skull in particular looks stunning. The plain background and single color makes it look like a tinted X-ray. Completely takes away what a thermal image usually looks like. And your technique of heating it from one side is giving me a vision of a thermal flash I never thought off.

You gave me some new ideas for things to try.

***

I have been shooting images like crazy, on the street and often at parties - where there is usually no lighting or smoke so you can't see or photograph normally. I like to use an inverted grey pallette because it gives a great contrast and that helps our brain to see fine details even with my entry level imager.

I took my image with ThermalCamera+ and the new feature to his the palette and data burn on. Superresolution is on medium and image is upscaled by nearest neighbor zooming. Some are lower resolution, because the superresolution icon hasn't turned green due to too much movement - I have not fully understood the superresolution feature and how to use it best - but I am making progress. The new shutter option is really great for shooting on the go or not looking at the screen.

Subjects are scenes from parties and also some street photography.

I think about them more as special effect photographs and not thermographic images. The pure greyscale helps with that. For best viewing experience I suggest to move away from the screen a bit till your brain ticks and visualizes the image like magic.

It's quite effective to active heat objects with a heatgun or a heat flash, and the most insteresting thing is that if ofthen shows hidden structues under the sufrace when active heated. The US Navy did studies on using thermography to inspect aircraft fuselages for cracks and wear and tear and measure the plate thikness.

I have used it a lot to find corrosion under painted surfaces. The corrosion lights up like a xmas tree. But it only works where the corrosion is covered by painting.

I wonder how expensive such a camera is, must be multiple thousand. But such high framerates and radio metric videos must be top end features.

For the gallery purpose of this thread:
1. Trees in front of the night sky, look somewhat like human lungs.
2. Flattering hair with a hot iron.

I took the first image while attempting to image the clear night sky, but there is a lot of noise and also some bias in my sensor. I wonder if taking multiple exposures, with the same palette and temperature range would reduce the noise and show if there is any signal in the night sky. But I somehow need to take darkframes to subtract sensor bias and deadpixels - the capturing all already does part of this, but I want to capture some flat images that I can use in the stacking software.

That much money can easily get you a 1280x1024 or even 1920x1080 LWIR camera - but not from FLIR. They do tend to overprice.

Resolution isn't the main selling point, high framerates up to 240fps on a crop and 120 full sensor(if I read the datasheet correctly) as well as radiometric video is worth the money. It is a targeted towards research anyways.

Ultrapurple is the best example. He had multiple ThermApp imagers. Those aren't targeted towards thermography like the consumer products from Flir.

You can apply a lot, but not all, photography tricks to thermal photography to make the best out of your image. But there is a resolution threshold you need to create something that is displayable on a computer screen or mobile phone. 80x60 won't cut it, even if you try really hard. You need at least 6times such a resolution in my eyes: 480x320 or greater. Next feature that is doing a big part in the quality and creative capabilities is lenses. You want the option to change lenses, not just put more in front. Also the focussing of a good Ge lens will improve the image by a big margin.
It's always great to have powerful software to finalize your images in post. But don't just shoot something raw I the field and make up the final look at home. Best is to bring the idea for color, stretching and gamma before you take the shot.
For flir radiometric images you can use various software: FLIR tools and Pallette generator by MyThermalWorld. The sticky in this subforum contains a really powerful piece of software that works with different cameras and file types and let's you edit thermal images in post.
There isn't really a market for Thermal Photography - more for Thermal Imaging; but it's doable and really interesting.

I agree with Vipitis (and thank you for your kind words).

Most of my cameras are not intended for precision thermography, which makes them much more affordable. But resolution and lens choice are vital.

You can get good results with a 320 x 240 or 384 x 288 sensor, which is roughly the same as a VHS video tape (remember them?), which the market considered acceptable for moving images for years. Using superresolution (shaky hand) techniques can improve on the effective resolution by up to about a factor of 1.5 or 2; multiple exposures (pan and scan) can give you extremely high resolution of a fixed subject, provided your lens is capable of breaking the subject down into small chunks. Think in terms of visible-light gigapixel photos made with a camera on maximum zoom.

Higher resolution sensors can give sharper results. The 640 x 480 class is very nice, although if I could afford it I would definitely buy an XGA (1024 x 768) or SXGA (1280 x 1024) sensor. I'm hoping that the new generation of sensors from China may make this possible in the next several years.

The right lens - or interchangeable lenses - make a difference, too. Wide- or narrow-angle lenses need to be chosen to suit the subject. I would love to have one of the 25-250mm (class) motorised zoom lenses that are out there, but they remain well beyond my pocket. For general looking around a short focal length (eg 6.8mm) works fine but for detailed work a longer focal length is very useful. Also, if you have more than one lens you can combine them for microscopy and similar work.

Most of the time I find I do my thermal work in black and white, although I have managed some pleasing images in false colour. Vipitis is right, that one can do a lot in post-processing if you choose. I tend to use ThermViewer with my Therm-App cameras, because (a) it gives decent results and (b) outputs a data file of the actual values of each pixel. I haven't started using these files yet but I figure they're a kind of insurance: I have rescued several visible light photos courtesy of the RAW files, and I suspect I will have the same latitude in the future with the thermal equivalent.

Frame rate is an interesting concern. I find it much easier, and quicker, to focus my 25Hz Therm-App cameras than their 9Hz brothers. Trying to maintain good focus on a moving object is quite difficult with a 9Hz frame rate.

That leads me on to focus. If you are considering using a thermal camera for 'photographic' purposes then adjustable focus is a must, which narrows the choice of devices. Any number of thermal images that would be very attractive are, in my opinion, ruined by the poor focus - either due to the limitations of the device, or because the operator didn't really understand what they were doing. Despite the remarkable things that one can do with software, sharpness really cannot be dialed-in in post!

Cost of hardware is the big stumbling block for most people, me included. I would recommend putting money into the best sensor you can buy, along with a single middle-range lens, with the idea of getting more lens options later. The smartphone 'dongle' thermal cameras generally offer good value for money, but don't have quite the same performance as the research-grade imagers. For 'photographic' use I would usually choose more pixels over accurate thermography - but at the same time it's really important to make sure the camera has good noise performance. Granted, noise reduction algorithms can help, but - as with focus - you're always better off getting the highest possible quality in the first instance.

Finally, don't forget that whatever equipment you may or may not have, image composition is key. I know I have made (and published) many badly composed images but the basic rules of composition work just the same whether you're working with paint, pencils, photography or thermography. 

I know I've rambled on, and I'm sure many others will be able to add their wisdom in far fewer words. But if anyone wants to discuss thermal photography privately, I'm happy to do so via PM and thence email.

My first panorama test using the TE-Q1 with FLIR 36mm f/1.2 lens.
This is a ~3MPixel stitch with Photoshop using every 12th image from a raw video sequence exported as PNG (132 images in total). The greyscale conversion was adjusted to cut some of the real dark/bright spots to get reasonable contrast in the raw basic images. The first one is without any further processing, the second one has increased contrast and some sharpening.

@Vipitis: Thanks! It was 5 or 6 sweeps. The total sequence has ~1800 images and just took every 12th without any checking of sharpness and so on. I am not sure if Photoshop does stacking. I have a quite old PS3 version which I think just blends parts of the images together. The noise actually is quite low on the TE-Q1 and I have to admit the temperature range of this shot is quite high: from ~-30°C (bare metal reflecting the cold sky) up +35°C (of sun heated black roof tops) apparent temperatures - so the noise is not really visible here.

@Ultrapurple: yes without doubt, but as I exported 8bit pngs only it did not want to push it and play very much. At some point I will try to export to 16bit tiff and stitch those together which should then give a lot more possibilities for post-processing.

I just tried the same or similar with the Lepton3 and 13mm lens but. The issue here is I had to sweep by hand w/o much control of the image and so a lot of images are blurry and it turns out that Photoshop limits to 200 images for stitching... Not too much for such small input images. Plus the images are really small and often without a lot of features to detect which makes it almost impossible to get a useful stitch. I tried quite a while but PhotoShops manual assisted stitching always crashes at some point... attached is the most I achieved with this so far. Autostitch also didn't do too good (see the second image).

Nice Turbo there ;-)

Edit: @Vipitis I actually messed up the sweeping a bit as you can see in the raw stitch of the above image (scaled down 2x).

yeah, they use a top end camera, two different lenses. And motorized pan tilt. It is like making a scanner again, but with a 1million pixel detector, and 2 hour capture time.

I like that even some people at flir are interested in a photographic approach to theraml imaging, but you can see and feel the difference from a cooled MWIR to a noise uncooled LWIR microbolometer. I wonder if they managed to stich those into radiometric images so they can apply color palettes easily.

I still want to see a super high resolution portrait with like 50MP and really really fine thermal resolution of like 10mK.

It's a long distance, so possible atmospheric interference. A stiching artifact, or warping from the stich. For me it looks a little like bad flir interpolation with those rainbow palettes.

I love your idea of using a room heater as 'lighting'. You've just opened up a whole new world of experiments.  :-+

(I'm not sure that I'll be trying to persuade a cat to sit still under several kilowatts of heaters, but inanimate objects might work well).

In my case the room heater was just a tool to form the pallette so it tops out higher and only a few parts of the cat turn color.

For using heat as illumination tool, you need to check out what MyThermalWorld has posted here and on his Instagram. The combination of a green hot to white cold pallette and using a heat source to heatup your subject from one direction, results in something that seems like a tinted x-ray.

I am looking forward to your experiments, as the idea could be used for a lot of objects that don't look like anything when their temperature is about the same in normal.

Posting here again, to bring pictures back into the forum - it has been text post with technical stuff for weeks, and only issues being talked about in the past. I finally got a stills camera for visual and have been spending my time there leaving thermal behind, but I have to learn about processing again and therefore I picked up the Palette Generator and played around a little:

I would prefer to not have this stupid flir radiometric jpg - but blurred image to show you here. I much prefer the rendering of the Thermal Camera+ app. I am giving you all version of the file to make the comparison on your own. Maybe it is possible to take a greyscale image and apply the palette as linear scaled LUT...

it is a little tricky...
I am using my Therm-App HZ and of course Therm-App-Plus and Therm-Viewer - I have started using Therm-Viewer's super resolution options but the photos seem to be doubled in size simply, and a bit blurry(probably my fault)- what other techniques can  I do?

I take it I should try messing around in Photoshop - I have so far only used Microsofts image composite editor for panoramas- but i presume that would work for what you callshaky hand techniques- which I am guessing is multiple photos of something- combined.....

You shouldn't be upscaling the compressed preview JPEGs - the camera packs a fully raw(uncompressed) 16-bit image into the JPEG. You can extract that and work with it instead.
Though I am releasing a hack that will let you force the JPEG quality to 100% in-camera soon, among other things(like short video bursts).

Very interesting carpin..I have had an eye on this new player.

If you have the ability to put up some more examples, video, pictures and just overall how it stacks up in regards to it nearest competitors like the basic Therm app & Therm expert with also 110k res.
Whats your impression sofare? if you have the chance to make a review or a walk'thru, fx in a new thread or perhaps Xtherm thread would also be very informative for me, and not least of you have first-hand knowledge about its main alternatives and able to compare it...
Congrats with you Xtherm..

Thanks Xtherm looks good... But I want that full review - and pricing/availability information. Competition is great for the consumer.

I don't think you will be able to see a laser midair. You would have to see the heat difference between air molecules or relfctions of that, but wavelengths of laser and LWIR are much larger then those molecules, so unlikely.
You can use alder to heat up a spot or a whole object and see how it transfers heat into itself, I think Ultrapurple did some Experiments with hobby lasers, you can find it on Flickr.

Because this is a gallery, every post should contain an image - I like the idea.

Subject 1: Sony RX100M4 on a Manfrotto befree live shooting long exposure of the clear night sky
Subject 2: clouds in greyscale during a cold night for a shitposts on the astrophotography subreddit(not done yet as I need to find a proper way to downscale those to 1:1 pixel size for processing)

I spent a lot of time shooting and editing visible stills in the last few weeks, but I will pickup my thermal camera a little more on interesting subjects and try to find some stories to tell - potentionally with a combination of thermal and visible.

Useally dust particles the laserbeam interact with and makes them visible and it was this interaction.
But even if these dustparticles are pretty big in regards something like molecules. I would reckon you still need a sensitivity able to sense this heat-energy of massless partcles interact with these dust particles. .

You can actually see these 5 to 7watt blue wavelength beams and the energy/heat messing up the dust-particles.. .
and was wondering if third-party interactions like , dust, fog, foam etc could help on the matter.
But need to try it out, but a Seek pro is certainly not the most sensitive thermal cam on the market  :palm: when it comes to small heat differences and like fx 5w 465nm laser beam interacting with dust particles in air..
but likely need to try and error.. just a noob on thermal sensors and the risk of hurting these and usually optic-cam-sensors and high powered-laser beams are not friends..
These intense beams and this bright intense light loves tumbling the optic cam-sensors at angled recordings.. how it is with thermal-cams sensors. I don't know if this intense light (offcourse not direct) can hurt these thermal-sensors.

Hm, those lasers are more powerful then I thought. If you have the possibility to try a scientific camera that is cooked and works in MWIR... But I don't believe even Dusty air is a medium good enough to visualize the beam. My knowledge in lasers is not dry deep, and I am sure it's dangerous to work wit gasses that heat up fast enough to show on a thermal camera.
The basic rules is that you can only image something with a thermal camera that is able to have a shadow in visible light. Which isn't true. But every matter in the universe that has a temperature of more then 0K(so the whole universe) is emitting IR radiation that can be detected.

It's late, but I would be excited to see this.

Also, definitely recommend getting that RAW data for photos. Major difference. Here is the exact same photo twice - first as it comes out of the camera and up-rezzed to 640x480. Next by pulling the RAW data and up-rezzing that to 640x480.

Here's another example of what can be achieved with the RAW image and a little work. The first picture is the original image from the camera, the second is the same exact photo except it's the RAW image extracted then cropped and zoomed with a fine-tuning in Photoshop. There is a whole lot of detail there that I never would have guessed could be pulled out.

Edited: to make both images same size.

Wicked shots above and welcome.
Looks good and certainly tempting to take the plunge on one of the budget 288x384 res. - a minor step in res but the noise seems somewhat better but hopefully, we will see some evolvement and price decline on the VGA-res microbolometers in the coming years and numerous wafer approaches
But still pretty blown away of how much I actually enjoy my Seek pro-purchase Fast frame iOS (290USD) and this fascinating world of thermal-information from an el-cheapo-noob-standpoint

Subject: My hot face on an insanely hot day after a trip to the gym and a cold bath at home (we have extreme heat here in Scandinavia, we almost daily set new records, certainly not normal summer-weather here, but that heat-scenario seems to be the case on a good part of the globe for the time being)

In this heat, where throttling easily takes place in these small thin ultrabooks, I decided to finally thermal-repaste the CPU/iGPU and the dGPU dies with some cheap paste (all sub6USD delivered) I had purchased from Aliexpress a few years back to be used with 9mm and 5.6mm laser-diode-sockets so I could easily interchange the diodes and not have to copper-press fit them.(had 3 kinds of paste, the ones in the picture, used the TG1 I likely should have taken the Shin Etsu
But it did certainly make quite a huge difference in temp-values, and found it pretty wicked that you could actually see what part of the CPU-die there where directed and in play' thrue the thermal-camera and if it was the up part or the down part or it was all over the die or first up and then centered down. (video is while a Geekbench4 benchmark-run is in motion)







and just a thermal view of the heat pipes effectiveness and different palettes. (iOS own screen-recording feature)

what file formats do you use for stacking? Do you get raw 16bit tifs and adjust the histogram afterwards?

Sadly my wide fov isn't great for panoramas.

Agree, the app is disaster. And with an update they made the app even worse. Though they fixed  dead pixel calibration, everything else they ruined.

I create 16-bit grayscale PNGs (this is all custom software), stitch them in Microsoft ICE (with patch, as described here: https://www.eevblog.com/forum/thermal-imaging/image-stiching-with-microsoft-ice-2/ ), and then create a PNG file - still at 16-bit. Then I post-process them in GIMP 2.10, first using "levels" to map the interesting content to a manageable range, then using curves to ~equalize the histogram (i.e. use larger amounts of output range for more interesting regions, and compressing down the uninteresting regions). I'm still experimenting with tone- and gradient mapping.

Camera: Thermal Expert TE-V1 with stock 19mm F/1.0 lens from Umicore.
Processing: none
This is a raw image with only minimal cropping of the very cold sky reflections on the bare metal using a FLIR-like pallette - the grey one is at fully dynamic range of the image.
As a side note: the depth of field is quite low with this lens - so only the center portion of the image is really in focus. The soft region to the front and back are due to out of focus blur. This combination is really sharp and has a very flat focus plane. My Q1 had some shift of the focal plane from left to right, this one not.

Little bit different... but it is a gallery so it fits here:

http://coolcosmos.ipac.caltech.edu/image_galleries/ir_zoo/zoo.html

this is from an old educational website that NASA made to explain infrared. The actual website today is really great if you want to learn something about Infrared in general and especially about infrared astronomy.
http://coolcosmos.ipac.caltech.edu/

the new galleries have sliders to switch between visual and infrared.

The weather is getting colder here as Autumn falls, so it was time to switch on the office heater. And, of course, time to check it was working using a thermal camera rather than risking waving a hand in its direction to test for warmth!

Your shots are great, they inspired me.

So I went out around the house with my phone and my new lens and looked for the next best tree. Lucky there is a really nice tree against the sky just around the corner. It wasn't easy to lock the temperature scale to get a good image because the vignetting plastic corners are always like 26C and ruin the histogram.

That is a superb piece of work, mahony!

On occasion I have used a low-end Gigapan scan mount to make panoramic images such as this one, which I never got round to completing:



(This used a Therm-App 384x288 with a 19mm lens and x3 telescope, if I remember correctly; it was too unwieldy to wave around by hand. Image Composite Editor, though, didn't like all the areas of black and couldn't manage to stitch the image, so I ended up doing it laboriously by hand.)

Experience shows that, in most instances, hand-held pan and scan works well enough, provided you make sure you have good enough coverage (and that comes with practice). This image was a hand-held composite:



As was this (the visible and thermal images were taken from slightly different positions, to my enduring annoyance):



Either way, I salute your experiments and look forward to seeing more results.

Your shots a great, they inspired me.

Thanks!

<snip>
It wasn't easy to lock the temperature scale to get a good image because the vignetting plastic corners are always like 26C and ruin the histogram. I also had to lock the automatic image tuning(shutter) so my panorama is having the same "exposure" overall.

That is one of my biggest problems too. ThermApp Plus for the Therm-App camera lets you lock the temperature range, which helps a lot. If you have access to the raw data from the sensor, and can process that, you can lock the sensor range that way.

If you're working in monochrome you can of course apply a correction to the image in <your favourite image editing application> using a 'bull's eye' that lightens the corners. Many image editors also have vignette correction options, which will do the job for you. It's tedious doing it on 32 or more images!


I did 8 in a row and 4 rows and 8 columns, although I somehow only have 7 in the first one... ICE was able to fix it for me.... there are a lot of stiching errors due to this being handheld without any lens correction - but the result is nice. I have no clue why the superresolution sharpening looks this agressive, I might have to change my settings here.


Even with a low resolution image sensor you can build up high resolution composite if you can find a way to narrow the field of view. I was lucky enough to acquire an x3 Keplarian telescope (mentioned earlier), which turns a 19mm lens into 57mm, albeit at the expense of aperture. But if you have a hot target that's not too much of a problem.

 

Keep your eyes open on eBay! And, of course, make sure you get something that's LWIR rather than MWIR.

@Ultrapurple I don't see an "L bracket" in that photo.  Did you never receive the bracket you ordered long ago or was it not as useful as you had hoped?  I don't recall seeing anything more on the thread where you were looking for something 3D printed.

All I see here are the standard rubber bands and duct tape.  ;)

Don't knock rubber bands and duct tape!

All joking apart, that was the only photo I had readily available to illustrate my comment. I did get the various bits of bracketry I mentioned and did manage to contrive a reasonable mount where everything lined up. Unfortunately life took some "interesting" turns (more than doubling of workload due to a colleague becoming seriously ill for many months, plus a family bereavement) and I haven't had the chance to do anything thermal this year - or, really, with regular photography except for a couple of work assignments. That's also why I've been absent from EEVblog for so long.

Meanwhile, a lens like this may show some promise for creating hi-res thermal panoramas - provided you've got the patience to take the hundreds or thousands of images required:

(click image for access to full resolution original, and notes)

 


More on this lens later, when I've got it working properly. It's a bit off-topic from "thermal imaging gallery" so any discussion should probably get its own thread. I am in private discussion with a forum member about how to get the lens up and running: it is not as simple as just whacking a sensor on the back.

Thank you very much! Very nice reflective lens this may give some nice long range shots!

I finally got the 100mm on and threw it onto my DIY Pan-Tilt to get some test shots and this one of the moon. The moon diameter in the image should be ~51 pixels at its current size (~8.7mrad) and the iFOV of my combination (0.17mrad).

I plan on mount the TE-V1 on my beginner-telescope too (650mm f/5.6) - not sure if the rather small aperture will give any useful imagery but at least it should be ~330 pixels+ in size than...  ;)

To be honest - I expected a bit more.  ;D But maybe I really get something out of the telecope from the moon. The sun maybe interesting too … we will see.

But anyway what I intended to do was a first pano-shot with the 100mm and here we go.
The pan-tilt range (see images 2 and 3) was set to 24°x12° and I just used 142 images of roughly 2000+ available. Again 5MPixel+ but on roughly the same FOV as the stock 19mm lens.

The focus is already a bit off at close range due to some vignetting and quite shallow depth-of-field plus some of the detail is lost due to camera movement and the stitching too.

Played a little bit with the TE and the 100mm again. Subject here is the Zugspitze mountain south of Munich. It is roughly 80km away and was completely invisible by the naked eye today - but quite good to see in LWIR.  ;D
The tree line in the foreground is about 800m away.
The first image is an average of a short sequence of 60 frame to get rid of some noise - the second is a single raw frame from the sequence, just as a reference of the noise reduction.

Edit: I also did an accidental move across the (already quite low) sun. Image 3 is a 2x logarithmic scaled version of the raw image on a white-black-blue-red-yellow-palette. It is always interesting to see how low the atmospheric scattering of the suns energy is in LWIR compared to all other optical wavebands - there almost no halo around the sun even in this aggressively spread image. The bolometer recovered the heated pixel within a couple of seconds - nothing to spot after roughly 20s...  ::)

Perhaps it's time we started asking Jinhua (Mr ThermViewer) if he would like to consider extending his software to cover the ThermalExpert cameras. ThermViewer is a great app that gives a lot of manual control, noise reduction (and background noise elimination) and not only outputs moving and still images in various forms, lossless and otherwise, but can also produce data dumps to file.

I honestly don't know how much ThermViewer costs, or if it has been made free. I was a beta tester, particularly for the Therm-App Pro.

In the professional world, I believe the software to exploit thermal imaging data can easily cost as much or more than the camera itself. So paying up to, say, 5-10% of the cost of the camera doesn't seem too bad.

So, probably around 5% of the cost of your thermal camera.

The alternative, for ThermApp cameras, is Therm-App Plus, which does have some excellent features (in particular, manual level control is better) but it doesn't have superresolution or drive the Xtherm cameras. On the other hand, Therm-App Plus is significantly cheaper than ThermViewer.

My images also highly increased by moving to a premium app. It was only very small price but it god rid of the stupid blur FLIR is forcing upon us. I had an ongoing conversation with the developer of ThermalCamera+ via email. As far as I know development halted but there are still lots of improvements and bugs to work on.

This being a gallery here are some images:

Played a little bit with close-up work using the 14mm Ophir lens and the 35mm.
With the 14mm you can get as close as ~30mm to the subject leading to the Euro coin being full screen than. The resolution here is roughly 48µm per pixel or magnification of ~0.3x. You might be able to get even closer, but the lens was only half a turn screwed into the the adapter in this configuration AND you already start getting serious non-flat image plane (the borders of the coin are already blurred noticably) and depth of field is really shallow. With all the longer focal lengths you need even more distance between lens and detector for similar working distances ... with some modified adapter I think 1.0x magnification might be possible. Anything even higher might be possible with two of those lenses or maybe a combination of the 14mm and 35mm?!

Somewhere - ebay.COM I think - I saw someone offering a macro extender ring for Therm-App cameras but I think they would work with other cameras. The price was something like US$40. The curious thing is that the vendor claimed to be in London but even searching on the eBay item number it did not appear on ebay.co.uk. Go figure. Anyway, it loomed like the perfect cure for the wobbly lens macro issue. Haven't tried one (yet) though.

Hey Ultra, do you know of a easy way to change palettes after a photo is taken? I have my Therm -App HZ and have been looking for software to easily do it- I can somewhat do it in Photoshop, but it's finicky and tricky, even when I try creating custom gradients.

I see IRT Cronista is a thing, but apparently only demo versions can be obtained that last a short time- so that's no good for the simple post-altering I am wanting to do in particular....

I've not really explored this. I often manipulate by converting to RGB or HSL or CYMK and playing mix-and-match but that's my limit and I very rarely post the results. I have a feeling that Paint Shop Pro (which I still use after all these years) has a palette load/save function and I'd expect other applications to have similar functions.

Wavelength Pro was/is a piece of software intended to manipulate images from a multi-spectral viewpoint, and may be of some use.

I regret that I haven't read the joe-c software thread but someone more knowledgeable could doubtless tell you if the software there would meet your needs.

I don't have Cronista but I do have ThermViewer, which produces text temperature dump files and suchlike. Give me a little while and I'll send you a PM with a link to some sample files and the corresponding images.

I think ThermApp Plus also does something similar. Again, I'll investigate. I know it can also produce a 16-bit raw TIFF but I've never had any luck exploiting that data (others have, though). Work beckons at the moment but with any luck I'll get something to you in a day or so.

do you know of a easy way to change palettes after a photo is taken?

I've not really explored this. I often manipulate by converting to RGB or HSL or CYMK and playing mix-and-match but that's my limit and I very rarely post the results. I have a feeling that Paint Shop Pro (which I still use after all these years) has a palette load/save function and I'd expect other applications to have similar functions.

Wavelength Pro was/is a piece of software intended to manipulate images from a multi-spectral viewpoint, and may be of some use.

I regret that I haven't read the joe-c software thread but someone more knowledgeable could doubtless tell you if the software there would meet your needs.

Hi all,

I've got no experience with thermal imaging at this point, hoping to buy a thermal imaging camera soon so I've been lurking in the forum for the last week reading everyone's informative posts.

Thought I'd signup so I could share the following in the hopes it might be able to do what you're looking for.

I have used an open source program called Paraview for some finite element analysis work which uses palettes to show stresses in materials similar to those seen in thermal imaging:

Might be worth a look.

Microsoft Image Composite Editor also works pretty well and uses a very simple drag-and-drop interface - it even takes care of figuring out in what order you made the images. This thermal panorama of Weymouth beach is 2341x470 pixels and was made with a 384x288 resolution Therm-App. Click image to enlarge and get more info, or click here for the full resolution image.

The white hot image is very good and hints at what it's possible to achieve. The palette in the colour image is really wild and wacky - I approve! The tractor looks very interesting in that version, though the colours on the far left side of the pile are striking too.

Yeah, neat program. Not sure why it decided to tilt the trees on the left side at a weird angle. Did you use a tripod for that panorama at the beach?

No, the beach panorama was done hand-held. If I remember rightly I simply swept left to right and back again.

The following hi-res panoramas were also all done hand-held, some in difficult circumstances (eg for the first image, watching out for armed guards in Egypt - I wasn't sure if it was legal for civilians, particularly foreigners, to have thermal cameras! Separately, I had a narrow escape making a thermal panorama on the Aswan Dam, where the guards are always pretty twitchy).

Click to go to each image's Flickr page, where you'll find notes on how each was made. Most were created from multiple individual images, hand-held, where I just guessed where to point the thermal imager each time. Others were made from manual pan-and-scan video files. I have made some large panoramas using a Gigapan head but the results were indifferent - and it was hard to interface reliably the scan head to the mobile phone.

Apologies that some of these are probably re-posts.

        

This is one of my very earliest panoramas, made with no manual controls on the thermal camera and hand-stitched. My technique has improved a bit since then:




And finally, this proves that you don't always need a panorama to make a great-looking thermal shot. It's a single image from a 384x288-resolution basic Therm-App camera.

Nice photos. Do you find it better to make images of buildings in the day while they are heated by the sun or slightly after dawn or dusk as they are warming up or cooling down?

It depends what you're trying to achieve. If you're looking to detect heat leaks from within the building then you want a nice cold night during which the heating has been set to maximum.

From the artistic viewpoint, there is definitely a thermal phase lag between elements of a scene (eg a building). A joint between (say) wood and stone, even if covered over with the same paint, will show this easily: the wood warms up more quickly than the stone, but the stone stays warm longer into the night. If you have the luxury of time on your side then you can pick your moment to make an image and choose the contrast that pleases you. Mornings will often be quite 'flat', followed by relatively rapid warming of the high-emissivity, low thermal mass items. As the day wears on the contrast is likely to lessen as the ambient temperature reaches its peak (about 2pm 'solar' time) and then, as solar irradience disappears, the more thermally massive things stay warmer longer, plus or minus emissivity. The short answer is that I haven't found a 'best' time - it's complicated by weather, whether the object faces the sun, local shadows, and many more variables.

Sometimes, the thermal image is almost indistinguishable from the visible light equivalent:



Sometimes, thermal image contrast can be fierce:




- that image was taken within minutes of the crest, both at Pembroke College, Cambridge. The crest is above a gateway to the courtyard, and I was standing more or less under the crest when imaging the buildings. They surround a courtyard and the walls were in shadow (sun to the left), which is why they're so cold (blue). But the slate roof was in blazing sunshine so it heated up to a significant degree. (There's more to that scene but it serves to illustrate the key points). It was an interesting challenge to retain some detail at both extremes of temperature.

Perhaps most obvious effect of morning warming is this panorama of Aswan High Dam (incidentally, this is the image that, to date, most nearly got me arrested or shot). Looking north from atop the Aswan Dam in the morning, the sun has already started to heat the left (west) bank but most of the right bank remains at a relatively even, lower temperature. You can see from comparing the visible and IR images that the sunny bits are clearly the warmest. But everything except the waters of the Nile and the sky are fairly warm, thanks to the climate.




There's no one 'right' answer. I would have liked to stay at the Aswan Dam for much longer (likewise the Pyramids and Abu Simbel) but the Egyptian security forces guard the dam closely and, as they had recently had a wave of 'terrorist'* attacks in the country they were understandably twitchy. Whilst touristy still pictures (ie photos) are (now) legal, videos are banned and I'm not certain whether I should even have even had a thermal imager in the country, let alone whether it was a good idea to use it in such a heavily militarised, sensitive area of such strategic importance.  :-//

I have yet to determine if there's a single 'best' time - but I'm having fun exploring the world whilst I find out.

(* Yes, I know one person's terrorist is another person's freedom fighter; this is not the place to get embroiled in politics).

While this forum is busy recently, I went out with my lens a few more times. I have trouble with sticking in ICE due to the upscaling and bad planing so more panorama shots will have to wait.

Here is a pigeon shot on my CST S60 with my DIY lens in whitehot from less than a meter away.

@Vipitis - Have you tried using the 'shaky hand video' technique followed by resolution enhancement in Registax or similar? You may find it's possible to do this for each tile of a panorama and thus get a considerable increase in resolution compared to tiling individual un-enhanced images (and also much better than creating a panorama from a single video).

@Ultrapurple
I use the Thermal Camera+ app to take my images because they are not horribly blurred like the FLIR images. The app allows me to take both: a radiometric .jpg(the blurry one) and a flat .png that uses superresolution in camera.
My current issue with post processing is the upscaling. As you can see in the image I posted it has a resolution of 680x907 - well that makes no sense. You have to know that the image gets upscaled by doubling pixels (nearest neighbor), yet from a 80x60 sensor with superresolution the 680x907 makes no sense. I asked the developer for an option to hide on screen elements to make stiching possible, so the palette, min and max temperature as well as a crosshair with point measurement are not visible with this option turned on. So images with additional information are saved as 508x640 with 28 pixels on the right side making the palette, and images saved without information burned in are saved as 680x907. This makes it it difficult to process. I need some kind of script to downscale the image to 1:1 pixel size, as stacking or registax for wavelets, finds differences in the upscaled pixel blocks. but 680x907 does not even divide into a multiple of 80x60, it is the image I would want to take because nothing is hidden behind some kind of overlayed information. If you count pixels, you will see some are 6x6, others are 5x6 or 5x5  - it is a complete mess and would require some perfectly measured imagemagick script to downscale, I have no idea why this is done - it could be to counteract distortion(although distortion is visible).

I have included an example shot I just took of my monitor. (the one with information burned in is taken without proper subtraction > you see 2 dead pixels, sharpened, and noise)




as this is a gallery enjoy a 1 raw panorama of a gas station I took last week.

Interesting - a very strange re-size indeed. I have no immediate idea what might be going on.

I had a quick play with your image to see if I could adjust it in any useful way. I'd be interested to hear what you think. Basically, I did some local tone mapping (contrast enhancement) and changed the gamma profile (curves). I'm not sure if I think it's an improvement or not.

E: On reflection, probably not.

Your point? I believe the CAT S60 is a FLIR - a Lepton core.

Vipitis said that the FLIR software was one of the things that was giving him grief. He is producing remarkably good images with a low-end device. I am fortunate to have a selection of higher resolution devices that are capable of fairly good results; even so, an XGA (or better) resolution sensor would help me improve further. But some of the lessons I learned with my first thermal camera, an Argus 1, have served me well as I got access to better equipment. 

I have a feeling Vipitis is destined for great things once he gets his hands on research-grade instruments, which I am optimistic will happen soon.

Well, let's address those. First of all, thanks for taking the effort to edit the image and adjust the levels. Sadly, the image I posted it merely a screenshot, as the original .tiff was too large to be an attachment on the forum. I didn't touch it up myself, but I needed to limit the temprange to have a uniform panorama. As far as I can tell the .PNG is saved as a 8bit RGB image, so the greyscale has only 8bit as well. That is not great because it limits the dynamic range output. To get true 14bit greyscale images out of the sensor, there is a solution which I stirred up again.
The embedded raw image in the FLIR .jpg should contain all the raw information and there are ways to extract them for further processing. But no way I tired has worked for me. Feel free to download any of my previous radiometric .jpgs(or I can send you a few) and try to get a 80*60 image with no compression out of it. Exiftool meta data says the IR resolution is 480*640 which is incorrect, FLIR toosl reports 240*320 which is also incorrect and inconsistent. Both raw extraction methods posted by tomas elsewhere in this forum have bad no working results as images seemed to have half the bit depth that was outputted but still the false high resolution. Thermal Platte generator is working with the images, but in the upscaled 240*320 version that FLIR tools shows up with as well.

***
This is a gallery so there will be pictures. First up is the failed panorama I shot in the night of a building across the street near the gas station. The alignment is off and ICE unable to fix it no matter what mode and values I give them. The vignetting isn't helping them either. I need to plan better, get better software and work on the 3rd generation of hardware.

To proof that the camera is usable for it's intended purpose, here is are some pipes running out of our heating system, try to spot the clogged pipe.

@Vipitis

Thanks for sending me the original files. I managed to get some sort of a result, but it was a fairly roundabout route.
First, I cropped off each image's top and bottom to get rid of the vignetting. Fortunately you had taken enough images with sufficient overlap that this wasn't a problem.
Next I did a quick auto-levels on each image.
Then I imported them into ICE using the structured image approach. For some reason it couldn't handle it - then I realised it was trying to assemble the images in 3-2-1 order rather than 1-2-3. I couldn't work out a way of changing this so I mirror-imaged each tile.
Microsoft ICE was then able to deal with the tiles and produce a composite. I used Auto-complete to tidy the edges.
Once I'd saved the image I opened it up in an editing app and flipped it back the right way and edited out some crud in the sky that had been introduced by ICE. I also did another auto-levels adjustment.
The resulting PNG was over the 1MB posting limit so I reduced it by 50% - as the original was significantly upscaled from the sensor resolution, this didn't detract much from the quality.
The result is below. It was an odd path, but it seems to have more or less worked!

(Edit: I hadn't spotted that ICE is perfectly capable of working with panoramas shot 'the other way round', which would have saved me the mirror image steps. I've learned something today!)

The story continues. After being unable to get a working panorama out of the first set of shots I did - even with help from Ultrapurple the result wasn't good. I went out to the building again and shot a panorama grid once more. This time I limited my palette to 8 - 18 °C(not true values due to lens) and locked it, then unlimited it again (so you don't get blue/red overflow). I also shot from 3 different angles to give you a better idea of the building.
Well the frontal view still didn't work out as I did errors in the overlap while waiting for trucks to pass by.

I present you two views of the same building from different angles. Both of these images use the same setting for palette, but as you can see there is a huge difference in the exposure due to the bias over time that is very apparent when you lock the palette. Both images are panoramas, later cropped and slightly adjusted in post.

Finally a clear night again!
Around 2 weeks ago I figured the TE-V1 is perfectly suited to be mated to my small telescope. Why? Because the outer diameter of the original housing almost perfectly fits the telescope eye-piece mount.
So now we finally got some decent 650mm f/5.6 LWIR optics  :scared:

Subject: The moon at roughly 90% full
Camera: TE-V1
Lens: Skywatcher Heritage 650/130 (image 4&5) and TE 19mm f/1.0 (images 1-3)
Processing: stacking w/ Autostakkert using ~200 frames from short sequence plus Photoshop brightness/contrast/sharpening (last image) - none for the rest

Image 1: moon @19mm (plus some of the roof)
Image 2: telescope w/o eyepiece but moon visible on secondary mirror
Image 3: recording PC w/ 'operator' mirrored image
Image 4: single frame from recorded sequence (unprocessed)
Image 5: final result

@mahony Congratulations! Your moon images are a joy to behold.

You may be aware i tried some moon shots with a comparable setup some years ago: your results blow mine out of orbit. Perhaps I may revisit the moon as a subject one day when my spare time situation (and health) improve.

Just wow and thank you.

I have been dreaming of getting a shot of the moon since 9th April 2017, the first time I captured me looking up with my thermal camera. I joined this forum just to talk of the thought of Thermal Astrophotography. I have spent hours if no days looking for information on the internet on research projects with daylight infrared satellite tracking, meteors; reap up on different scopes and instruments that operate in the LWIR spectrum. I found two papers that looked at the moon, but not taking a real photo of it. I spent countless hours in the cold outside taking timelapse of the moon rising and clouds passing by. I spent weeks talking to people about optics, telescopes and lenses. I became fairly active in this forum and check it multiple times a day and post on here deep I the night (it's 2.27am right now). I got to my passion for thermal camera art and spent days looking for projects and more days to contact artist and find out about names and websites. I made contacts to build my own little auxiliary lens to get closer to the moon. I calculated and modeled a mirror telescope that would give me the perfect framing. I am planning to chose a university course in EE and CS to work on thermal imaging(if any of you got ideas for internships worldwide to work with thermal cameras for 6-9 months before that - let me know btw!). It took me a year untill I saw the first proofs of my dream with Ultrapurple having made shots of the moon rubberbanding his ThermApp to a small newtonian telescope and rubber banding a few thermal lenses together with some tape and plastic bottles to build a refractor to spark my interest further. I saw the first real image of the moon with some detail in focus and knew it was possible.

Now you come in with an even better camera and lot's of effort to produce this stunning image. I thank you bringing that rush back and confirming my hopes. Giving me an example to show people it is possible. I will continue to work. Just earlier today I started to modify my own lens to fix the Vignettierung a little by recentering it. I also got the thought that a shortening the focus mechanism on both sides will give me better infinity focus, so that is under way. Tomorrow I am going to a photo meetup for large format analog photography shooting some architecture, I will bring thermal camera and lens because I can only shoot two plates.
Is there any place for a high quality version of the image?
Do you think more is possible? Did you see anything else at f/5.6 through the scope? Some stars maybe a right nebula like M42 in Orion? (It is supposed to be bright in IR, but I have found zero shots of it in LWIR, some from a orbiting space telescope and narrowband 12.3microns in the gallery I posted some time ago) maybe other planets like Venus, Mars, Jupiter, Saturn? They will be tiny but maybe worth a try and they are rather bright.
Sun is risky and will burn your sensor, maybe a special filter to only pass LWIR and reduce the heat in some way can make that possible.

Keep it up!

This is a gallery so here are some shots of mine from today.

Camera: CAT S60 -> 80*60 Lepton
Lens: DIY build -> auxiliary 19mm, 2nd gen.
Software: ThermalCamera+ by George Friedrich

Subjects: the saddle of a Brompton bike, old lady walking past the fence, a strange shutter error I got for the first time with a nice pattern.
Bonus shot: friend with scarf as a study

Okay, at said photo meetup we had interesting discussions and tried our best with some large format shots of architecture. While mine are probably blurry due to 3s exposure time and some shake and wind - I managed to shoot on Thermal as well. The results are great, we found a really good subject and the sun was just setting. I am feeling like I am getting better with this. I still need more planing and a tripod mount would help. Shooting a few images of the same tile could also be use for stacking before hand.

This is a 4x3 panorama cropped a little. No level adjustments here pure balckhot palette with delta span or 6-7°C IIRC - that is with using the unmeasured modified 2nd gen lens.
Camera still is CAT S60 running ThermalCamera+
stitching in ICE
Subject is a building called "Wolkenbügel" in Düsseldorf if you want to look it up!

Hi Vipitis,
I did not except that much feedback on the images - altough I was impressed what is possible even from the 'small' aperture (LWIR-wise ;)). I did not try any other subject as I just did a quick test before sneaking to bed … The moon is some very bright source - I think I have seen around 80K difference to the background or more with calibrated lenses. I assume all other subjects apart from the sun may not produce usable contrast. But I will try if I find time again. If you got any inputs wants worth a try: I am open to suggestions.

Actually the same might even be possible with the Lepton core you got in your phone - I got two of them pulled from 'dead' FLIR One G2's. Removing the lens is possible and attaching it to some (maybe small) telescope should be very do-able. Probably a small 300mm one like this 70€ piece: https://www.amazon.de/Unbekannt-Skywatcher-Dobson-Teleskop-Heritage/dp/B0098QKLTW/ref=sr_1_10?ie=UTF8&qid=1551210904&sr=8-10&keywords=teleskop+skywatcher (I got the big brother of it).

Small warning if experimenting on Leptons without the lens: be sure not to get any dust into it as there are bond-wires exposed. I somehow killed one line on the core i did a little more experimenting this might be related to this issue. The core still works fine but I have to fix this line in software  ::)

@Ultrapurple: I think you did some really good shot with your setup - the telescope was just a lucky finding and done very quickly (~1 hour all in). Wish you the best for your health AND spare time.  :-+
By the way: your mirror lens should give some really nice images too!


Back to topic - some pictures! As I am pretty short on time at the moment I have to dig out some 'older stuff'.

Subject: TE-V1 detector / FPA (corners of the FPA actually)
Camera: TE-V1
Lens: Ophir 14mm f/1.2
Processing: none, but focusing quite close AND pointing the camera to some cell phone screen (glass/mirror/anything highly reflective)

@mahony - those are very nice images of the inside of the sensor! Much better than my effort with a Therm-App. Have you more than one camera so you can use one to look at the other one scanning?

   

Thanks for your kind words. I'm pleased to say I'm more or less in good health again, though spare time is at a premium (as always). But just to show I haven't sold my cameras and gone off in a huff, below is an image from this morning of a Geiger counter that I recently acquired. (Why? Well, why not; also, someone I know is about to have some nuclear medical treatment so the first time I see him I'll dress myself in a hazmat suit and carry the Geiger counter prominently). Image made rather hurriedly with a Therm-App Pro (640x480), ThermViewer driver software and a bit of final tweaking in Paint Shop Pro. There was very little thermal contrast apart from that one transistor and resistor. Most of the bright bits are reflections in metal of the nearest hot thing. Me.

I have done a little playing around with the big lens (including taking it apart) but I have yet to achieve a clear, well focused image from it. That's probably because I understand its minimum focus distance is 20m, rather longer than any open part of my home, and I haven't really had a chance to try it in the great outdoors; although my neighbours are fairly tolerant they might wonder what on earth I was doing pointing a dustbin-size lens at their houses... Fortunately I have occasional access to a large, private outdoor area so when I next get the chance (and the weather is kind) I will continue my experiments. I've been told that it requires an additional lens at the back before it'll produce a clear image, so we'll see what I can find from my meagre collection of germanium oddities. One day, one day...

Ooh that trick to image the scanning is quite cool! Just hauled out a couple of cameras and sure enough I can see it too. I had it at a higher frequency (a few Hz); one camera was probably set to PAL and the other NTSC, which would give results in line with what I saw.
Agreed that mahony has some nice pics of a FPA - will need to have a go myself once I get around to making a proper mount for the close-up lens I got via the "is this lens any good" thread.

As for your massive lens, if you manage to find some specific info about the required supplementary lens (e.g. diameter, focal length) and don't have a suitable part in your collection, PM me and I can check mine.

I am away from home at the moment and don't have access to the reference  but I think Fraser told me it was a plano-concave lens that's required. Thank you for your kind offer of help - once I have had a proper chance to play I may well take you up on it.

While I am in between buying a real camera myself, and there are some crazy scope/lens listings on eBay as well... I am still playing with my current setup to get around the low resolution. The plan to modify the lens has slowed down again. An idea I am exploring right now is to compose multiple images into one. Not like a stitched panorama but more like a collage. The first one I would like to share is a 2x2 of portraits I shot with my camera and lens, I lowered the gamma setting a little to have a more appealing gain. I also edited this with some automatic filters and sliders on my phone after putting the collage together. I went for a look of an older iron palette, I can't remember exactly where I saw it - but it resonated with me... the low resolution and this kind of palette work, potentionally because I looked at many thermal images already. Notice that the individual images are also cropped into 1x1 aspect ratio - this hides the vignetting and makes the close up shots less apparent.

I will keep bringing my lens and camera with me and just get shooting. But deciding on a "real" camera can't be soon enough.

Interesting work as always, Vipitis - some good ideas there. It's amazing how  'humanising' a pair of spectacles can be in a thermal image: perhaps because, generally, the eyes on human faces blend into the rest of the nose and forehead in a thermal image but spectacles, which we are also very used to seeing, give us back a shape we are familiar with.

I suspect there would be some interesting research to be had in the area.

On a completely unrelated note, I had a chance to play with my thermal camera today for the first time in a while. I will try to post more later if there's anything usable.



(Made with Therm-App Pro 640x480 25Hz, 35mm f/1.2 lens, ThermViewer driver software, converted to an animated GIF using an app on my phone).

Edit 2019-03-26: Flickr has finally made available my rather ropey colour thermal video of birds stuffing their beaks on a swinging feeder (see third photo below - a still from the short video.

Amazing shots in this thread since last visit 4 months ago.. :popcorn:  but also a lot of "ohh damn I need one of those so bad" envy-moments  (been lazing it this winter with different wavelengths... that is usually my hobby-cyclus. - quadcopter in the summer & spring outdoors and laser equiptment and the fascination of massless particles in the winter and general electronic from a noob learning standpoint where YT often are ones learning source  :palm:

Subject: Cheap 1 USD Heating device from China
Thermal: Seek Pro Fast FRame.
attachement: 8 USD cheap ZnSe lens 5CM FL. (only YT video)
Device: Ipad 2018 recorded with Seek's own native recording feature and no filter or picture-enhancement all barebone.


Tried to check the crosshair cursor and how accurate it is, according to the edge of the heatsource.
Item is a 1USD eyelash-heater from China.
there is 1.2mm from tip to tip.


Not to shabby. not least at 1:17 seems spot on. (handheld)

@DaneLaw - thanks for the tip on  GIF  hosting. I managed another way, via Flickr, but it works out much the same.

Interestingly, the animated GIF of the sensor scanning is hosted here on EEVblog in another post. But, I suspect working with a phone is always going to be a bit more hit-and-miss than a desktop (or laptop) computer.

Your images are lovely, combining lasers with thermal imaging: definitely both fave subjects of mine.




I'd love to get a CO2 laser and see what its beam looks like to a LWIR camera. Not in terms of beam profiling (which I recognise is an important field) - rather,  just making the invisible beam visible.

(Evil, evil, evil thought: I wonder if a cat would chase the little red spot of burning carpet and whether it would learn to do so before or after losing a few whiskers and parts of its tail...? I can't stress strongly enough, PLEASE DON'T try anything like this for real!).

Hi all

new here.

i used my TE-Q1 to look at some chips sending data in my home automation setup. Mainly a Lora RFM95 module and an ESP8266 sending data.

The lora footage is not very good since the heat is very low but its possible to see the heat propergate thru the chip. The esp looks much more interessting on how the heat radiates from the traces in the PCB

take a look at the video

@agh768 - welcome to the group, and thank you for posting such a fascinating first image.

I got similar results when I looked at the multi-core processor on a Raspberry Pi. You can actually see different parts of the chip 'light up' as a benchmark exercises different numbers of cores and facilities. The links contain videos and notes.



Interestingly, unlike your excellent example I didn't see any evidence of the heat being conducted away via the PCB. Maybe that's why this version of the Pi had a reputation for running hot, and has been superseded with one that has a heatsink bonded to the chip.

So many users of the TE-Q1 here. :D What does the extra lense do? More field of view? Nice "green iron" color palette you made there. The pictures with cars is that after sunset too? Since the car shadows are cooler than the surroundings it looks like the sun is still up. When the sun is down shadows and enclosed areas tend to be warmer than the surroundings.

The 19mm lens is basically the most "tele" official option for TE-Q1, i.e. "zooms in" the most (and most narrow view). Not that much of zoom, really, but still.  Also, the most expensive lens, like 350€ at https://www.thermalexpert.eu/english-1/shop/lenses-and-accessoires/

Quick comparison of three Therm-App cameras and a FLIR SC660

1st image - Therm-App, 384x288, unmodified 9Hz, 19mm lens, Thermviewer, superresolution to 768x576

2nd image - Therm-App, 384x288, 9Hz camera modified to 25Hz, 19mm lens, Thermviewer, superresolution to 768x576

3rd image - Therm-App Pro, 640x480, unmodified 25Hz, 19mm lens, Thermviewer, superresolution to 1280x960

4th image - Therm-App Pro, 640x480, unmodified 25Hz, 35mm lens to give same FoV as 19mm on 384x288 cameras, Thermviewer, superresolution to 1280x960

5th image - FLIR SC660, 24mm lens, x2 upscaled to 1280x960

--- Edit

6th image - Argus 3, photographed off screen, due to the limitations of the camera's screen this image does not exactly represent the 320x240 resolution of the thermal sensor

7th image - visible light view of scene


Images 1-4 were made with ThermViewer set to its subjectively 'best' settings (essentially the same for all four images) and post-processed in Paint Shop Pro to give a more pleasing greyscale but are otherwise as-shot.

Could you make a comparison between Therm-App 384x288 and Therm-App Pro 640x480 with an indoor scene where there is little thermal contrast? The kind of scene that results in noisy pictures.

I second that motion!  Something like full grayscale spread over 1.6 degrees C; certainly no more than 3.2 degrees C.  Same for the FLIR, but you might need to go lower than 1 degree span.  ;)

Could you make a comparison between Therm-App 384x288 and Therm-App Pro 640x480 with an indoor scene where there is little thermal contrast? The kind of scene that results in noisy pictures.

Will do. Any  preference as to lenses? I have 13mm, 19mm and 35mm available. 19mm on both cameras gives exactly the same level of illumination (of course) but different fields of view.

Probably the fairest test is 384x288 with 19mm f/1.1 and 640x480 with 35mm f/1.1 - the lenses are the same aperture and, as seen earlier, have the same field of view.

Agreed, but the field of view is secondary in my opinion, since noise is the issue of concern.

would it be possible to export/upload png instead of jpg? the SC600 image above  shows quite a few jpeg compression artefacts (but still looks sharper to me than the Therm-App ones.) it also looks a little like there are sharpening algorithms applied to the FLIR one?

Folks - this is wandering off the 'gallery' topic so I'll start a new thread specifically on comparing Therm-App cameras. I'll update this post with the details when I have taken the relevant images and established the thread.

In brief answer to @polar yes, the FLIR images do come out fairly heavily compressed-looking, even though I set the save quality to best in the menu system. I have yet to investigate importing the images into FLIR Tools or other software in order to get better-quality saves.

Ultrapurple, not sure if your flavor of .jpgs works, but you can try your luck with the steps outlined here to get a raw image: https://www.eevblog.com/forum/thermal-imaging/flir-e4-thermal-imaging-camera-teardown/msg342072/#msg342072



this is a gallery so you deserve some images.

here are two vertical panoramas of a building I shot. It is nothing special and more like a test. They are shot with my phone and DIY lens. the pixels are upscaled by a factor of 5.66 and superresolution is enabled.

Hi guys,
I tried to get some nice shots of the sky with broken clouds - all panoramas and quite large. I did not expect the stitching to work as good as it turned out due to quite a bit of wind and moving clouds. But I am really pleased with the results.  ;D

Camera: TE-V1
Lens: Ophir 35mm f/1.4
Subject: town, landscape, cloudy sky (sun in image1)
Processing:
 - structured panorama shots with 10x8 (image 1+2) or 15x5 (image3) images in serpentine movement (8°/6° fixed position increments)
 - 8 images averaged per position
 - raw export to .png with varying gamma correction on almost full dynamic range (except sun in image 1)
 - stitching with Microsoft ICE
 - post-processing using PS (brightness/contrast - all images) and own tools for contrast limited local histogram equalization (images 2+3)
 - 50% resize and conversion to .jpg for forum upload (original images are 5MPix+)

I think I read something about reaching around 280°C already in the threads couple years ago. I think back then the higher temperature values were only available in some set of data. And even these days, the specification's limit might be given on the basis of how high it can give accurate enough values that they can hold the accuracy specification.  But -12.4 to 309.3, huh..?

In the new SDK code the temperature tables go from -30C to 260C (and clip there if input values would result temperatures outside that range), but those might be without ambient correction or whatnot. The curve starts to be quite flat by the high end clipping point, so there probably isn't much more range left above even if it was not clipped, but I'll probably check it when I start coding my own version.

So i managed to get an improved version of Seek Thermal (standard non-xr version) for 170$ (used, sh).I think it's a 2017 version, it has a manual focus ring, which is a pretty big deal.Compared to what i was used to seeing in the old version with fixed focus, which was more of a smudgy mess, this is a huge improvement.It can also focus up to 3cm.For this kind of money, it packs quite a punch.

Do you have any TE-V1 pictures from a low contrast scene? Like indoors in a garage or a basement. Or in a forest after sunset or during an overcast day.

Do you have any TE-V1 pictures from a low contrast scene? Like indoors in a garage or a basement. Or in a forest after sunset or during an overcast day.

I just did some testing for Joe-c's software and here is some indoors image with ~4°C temperature range in the full FOV plus the lens is only f/1.4 (compared to the stock f/1.0). This should increase the noise by a factor of ~2x.
Additionally post 243 on page 10 has two outdoor images of very distant landscape - one image is a single raw frame, the other an average of ~60 images for noise reduction. The lens here was f/1.6 - so even more noise to be expected ;)

The second image is cleaned up a bit using bilateral filtering - removes quite some noise but keeps most of the noticable detail.
The last image is a calibrated one using the stock TE-Q1 (not yet fully thermally stabilized) to show scene dynamic - the Q1 image has full range of ~5°C but the coldest spot is the upper right corner not visible in the V1 image.

If there is interest in more detailed data I can dig-out my DIY Dual-Blackbody and dial in some pretty close temperatures like 0.5°C and take some snaps with the stock lens to get a better impression.

edit: Small side note - the doors on the cupboard are glass - as is the door/window to the right and you can see a double reflection of my shoulder in the lower right corner of the rightmost door.  :o

As we are about it: I got some new SBC toy, namely a LattePanda 432 that arrived last weekend. Couldn't resist to throw on my software and plug-in the TE-V1 and take some snaps.
Works nicely so far an I like the 7" touch screen - this should make some nice portable IR recording box.  ;D

Holy batsh*t cr*p how can you get such a perfect noise free image!!  :scared: Is that really the quality of therm-app pro? It's funny that the better quality an IR cameras has, the more similar it looks to an optical camera.

Btw is it using black hot color palette and taken after sunset?

Therm-App Pro, 35mm f/1.2, Thermviewer, Microsoft Image Composite Editor, Paint Shop Pro X. Made from about 130 individual 1280x960 images.

Click the image to see more details and gain access to the very high resolution original (9176x4362 pixels).
Holy batsh*t cr*p how can you get such a perfect noise free image!!  :scared: Is that really the quality of therm-app pro? It's funny that the better quality an IR cameras has, the more similar it looks to an optical camera.
Considering the original image sizes vs. combined image size vs. total number of shots, it looks like there is on the average order of magnitude 4x stacking available for each pixel. That is 2x noise reduction (statistically, not necessarily so for each and every pixel, random chances and stuff; and depends on how the individual shots happen to be aligned/overlap each other).
Then the image shown here (not the huge combined original image) compresses plenty of original pixels into each pixel seen in the smaller image here, reducing the noise much much more. Do check the full size original at 1:1 "zoom", there is plenty noise left still.
The flickr description also clarifies the "black hot image".

Black hot images are about the closest in appearance you'll get to a black and white image taken with a visible light camera.

True to a certain extent, in an ideal world, however as far as I know Microsoft Image Composite Editor doesn't stack images for noise reduction (it's designed for visible light sensors where noise isn't such a problem) although it's possible there has been a bit of noise reduction as some kind of collateral gain from the stitching process.

You are of course right about the other points. Even a very noisy image can look usable when downsized by a factor of 10 or more.

For comparative purposes, I have attached a straight-off-the-camera shot of the square taken with a 13mm f/1 lens (which vignettes quite badly so ignore the corner and edge focus) and a straight-off-the-camera 35mm f/1.2 shot from the series that made up the composite image. Both made with a Therm-App Pro (640x480) and Thermviewer software; no other editing apart from using Paint Shop Pro to convert from PNG to JPG.

I'm pretty sure the focus was slightly off for the 35mm image  :-\ If I go back I'll have to make sure I tweak it better!

There is also an ultra-ultrawide shot from the same vantage point. The stitching isn't perfect but I haven't bothered to go back to do anything about it because I really wasn't terribly impressed with the image.

In order to make it fit the 1MB rule I've had to downsample it from the original ~18,000 x 5,750 (>100Mpix) to "just" ~6,000 x 1,900 (~10Mpix) and dial up the JPG compression.

Did this thermal imaging thread die, or subsidized by another.??. took a brief glance at the first 3 pages on the frontpage and nothing stands out
- same with the search phrase Thermal Imaging gallery..
Usually quite helpful these imaging threads, to see the ideal results people can achieve with their thermal gear, both new and old.

In regards to the topic, and showing pictures, as I'm necrohumping this Thermal Gallery..
I'm still rolling with my old Seek Pro FF (18Hz) from 2017 though do look to take the step-up for the best 384x288 (25Hz or above) alternative here in 2Q 2021, though still unsure about the thermal gain, going from 76.8k (320x240) to 110.6k pix. (384x288).. VGA resolution still demands to much money, as far as I can tell.

Yep, I recall it now, even notice own testing above (Im getting old) ...can also see Dave tested it after likely a fix at #358 (previous page) ..After all some stunning footage shots in this thread, not least the stunning high res-stitching from UltraPurple, and also recall outstanding DIY Astro shots of the moon, thx for the link.

Those are some amazing shots with a Seek Pro @DaneLaw,  were they made by some kind of panorama technique? - and focus stacking?
Thx  :), No picture stacking or multiple stitching, though some of them are with multiple lenses..(some of the cheapest kind from Aliexpress and eBay) US-ZnSe, CN-ZnSe, GaAs & Ge.. ranging from 7US to a tad under 20US with numerous different focal lengths.
I have put some Velcro thread on the Seek Pro (pictured below) and for multiple lenses.. I use a foam-tube, I then can put on the seek-front and still be able to turn the focuswheel.(useally one of these two approaches I use for macroshots)





On some of them, I used,focus-sharpening with an aspect of Ai  :bullshit:, but its a balancing act, as you often need to mask certain things, so it aint get manhandled to hard, as certain details will otherwise be removed without masking
Here is a before and after example.

Even a Seek can produce clean looking images with a wide temperature span and the typical super-smooth palette.

As an example, here is an image produced by the Seek app with the white hot palette autoranged:
1209598-0

Then the same palette applied to a narrower temperature range (this looks more "Seekish"):
1209600-1

And finally one with a distinct-color palette autoranged (extra noisy):
1209602-2

These were all produced from the temperature data in the same Seek tiff file.  In order to judge how noisy the camera is you need to see gray scale images with only about 3 degrees C span black-to-white (in my opinion).

I do like the effect of the focus-sharpening, though.  :-+

And I see the in-line image thing isn't working right here...

Your pictures look more like what comes out of my camera.

Somehow, @DaneLaw's pictures are completely noise free, with very sharp details...  I suspect he owns a very high end camera and is just too modest to tell us what it is!   :D

For example this picture posted by him has a resolution of 800x600, which is quite a bit better than what the Seek Compact Pro is capable of (320 x 240)...   Come on @DaneLaw, tell us what you are doing!  :D

Can I know where have you purchased the Camera and cost of it
If it's mine.
Then I got it from eBay on an auction back in late 2017 or early 2018 (It doesn't look like your cant go past 2019 in old account-purchase on eBay so I can't link to the "listing" also to put below info into perspective)
It was a seller from the USA, that I notice had numerous for sale' with no minimum price, and keep putting a new one up every time one auction was done, so I finally took the plunge, and got it for a tad over 300USD (it was listed as new Seek Pro iOS) but nothing else, not even the info that, it in fact, was a Fast Frame version (18Hz (FPS) not the standard 9Hz)

After I had won the auction the seller then contacted me and asked that I paid him directly  :scared: usually a red flag, but often it is just a tactic to circumvent massive eBay fees that are in play...but in general I had not a huge problem with it, as it still would be Paypal and my auction winning price was quite a bit lower then what the other ones had been going for (2017/2018), so the seller had an obvious motive to fx cancel and then put it up again and get a significantly higher closing price, and not least as I also wanted the seller to do something for me, and label the parcel at sub 12 USD, as otherwise, the price would elevate with another +50% after danish tolltax, + handling fee, + another 25% danish VAT of the total sum.
and in the past, I also got way better protection by having to go through PayPal dispute than fx using eBay support and their awfull-buyer-protection. that I'm not a fan of, even though one's payment is done by Paypal inside eBay... same with the time' that is like 3 months inside eBay and 6 months with direct Paypal, so circumvent the eBay-chain for the purchase, was okay by me.

But in general, there were quite a few red flags, and concluded that there was a huge risk' that the seller was a scammer, and likely not in the USA' as I could not validate his very Russian or east European name and the housing details in the USA, that he provided, same with the email.
But after I had talked with Paypal Denmark and mentioning all the red flags' I concluded that I had no risk whatsoever to go through with the transfer to his PayPal address, and the funds would be locked for a certain time' and in the worst case, it would be wasted-time at my end.

The item did not arrive in the time it should (not even close) and the tracking details he provided were also very weird and could not be used at all (no info whatsoever) but a few days before the deadline for me to start a PP-dispute for the money. - The parcel with a Seek Pro iOS to my huge surprise actually arrived and with a US shipping-out address..so I just concluded that the lack of tracking simply was spared, hence cost.

I later took a closer look at some of the other things he sold with no minimum price, and I notice many expensive Bushnell rangefinders. (also completely new)..
I don't wanna label people or sellers with wrongful names, but I do recall I later wondered about that eBay sale account (now gone), - as we here in Denmark have quite big issues with credit card scams, where people from abroad, hack credit card info on people here in Denmark and they then use that credit card to purchase expensive gear, that they then sell online from online auction sites.. (but I am only speculating here, no proof what so ever, from my end, the item was perfect.)


Somehow, @DaneLaw's pictures are completely noise free, with very sharp details...  I suspect he owns a very high-end camera and is just too modest to tell us what it is!   :D

For example this picture posted by him has a resolution of 800x600, which is quite a bit better than what the Seek Compact Pro is capable of (320 x 240)...   Come on @DaneLaw, tell us what you are doing!  :D


No sadly  ;D  Im still only rolling a Seek Compact Pro FF (the only thermal camera I got) but I do finally have the funds saved so I can take the plunge for one of the better 384x288 25Hz dongles for Android, like the Hti-301 or the T3S or if there is other better alternatives??

but I am still missing an overview of which dongle is the prefered to get here in 2Q 2021 as they are both pretty much the same price, the two mentioned above.
My budget is around 500USD for a 384x288 or around 1000 USD for one with VGA resolution (480p) though thermal camera-dongles with VGA resolution at around a grand, is still not in the foreseeable future, though I am one envy puppy' when looking at some of the shots on Flickr    https://www.flickr.com/groups/therm-app-users/  (admin of that group is one of the users here on EEVblog)

The 800x600 is just an image upscale.

The setting' I use most on the Seek App, is the one with these two-circles on top of each other, as there I can lock the span with the circle button upright, and usually point at something a tad warner and hit that round button, and you even have the temperature-value running underneath for the hottest part present...
It's the "preset" I use at fx 0:55 minute into this video where I'm looking at two tiny 1.25mm (131) resistors.  (I reckon it's these)
https://www.digikey.ee/product-detail/en/susumu/RGH2012-2E-P-131-B/RGH20P130BTR-ND/1143035

My prefered palette in the Seek app is the Tyrian and then get a span-lock a tad higher' than the subject, and also what I used with the SH72 soldering iron above and this UR65 quad below..

at 0:55

I fear that once you have a pro in hand you will be disappointed.  Note that the scene in the video has a 20 degree C span & if you look at the 2 minute point (and others) where he has the Prism palette you will see the more typical Seek noise.  My first image above has a few degrees lower span. 

I also encourage you to review my sample images in this thread:

 https://www.eevblog.com/forum/thermal-imaging/the-seek-thermal-core-development-user-opinion-please/msg2915972/?PHPSESSID=mhvdkk76c9vkpg6338q952b7h2#msg2915972

While there may well be a variation from one unit to another, most of the Seek images I have seen posted have similar noise if you consider the temperature span.

@DaneLaw could you post a Seek TIFF file of one of your beautifully clean scenes?  If you don't already know, in order to save tiffs you have to have the "save all data" option enabled in the settings AND you have to set the view mode to the one with the square of 9 squares symbol.  The tiffs are then in the "pictures" folder instead of the "images" folder...IIRC.

Save all data? Seek tiff? Is there even more secret menu to enable this?)))
I had seek compact-iphone, xr-microusb, pro-iphone, pro-typeC, proFF-iphone, seek shot pro, noise seemed equal on all of them, dont think that FF is a secret super pro grade for americans or itar-friendly contries))) Iphone models dont save tiffs in folders afaik and only save interpolated jpgs, resolution depending on iphones screen. Danelaw did some trick with "levels" to hide noises, and the scene was luckily rich it contrast, so photo with 17hz caption looks really good. 18hz photo has some large areas with low contrast and still low noise, maybe it was manipulated in post) and yes, the palette matters, black\white hot hide noise the best, rainbow\colourfulls the worst, ironbow inbetween. i found some good looking jpgs from non-ff iphone pro seek, but usually its noisy AF, see attachments))
Danelaw, 384 infiray models are step-up in regards of noise and chinese are ok with tricking customs, but you are really limited in lenses choice if you cant change the case to custom one with M25 or M24 thread(regular is M17). they stopped selling t3s with 6,8 mm lens on aliexpress so 13mm is only option( on the other hand, therm-app stopped selling all models except 384-MD so therm-app pro 640 becomes kinda unattainable dream($ Cheapest 640 alternatives are 640 flir scouts, infiray xeye6 and pulsar XP's, they cost far from 1000 used i guess. Recently got XP38 for 1800$, felt really lucky)) And even with dead pixels and thermviewer superresolution on t3s/hti-301, pulsar XP looks waay sharper. Flir is tad cheaper but has other disadvantages, xeye6 i didnt see used below 2400$(almost the shop price), either they are too good or too expensive for chinese loving hunters, so they prefered xeye3(384*288, it got a bit cheaper used, recently)

Awesome pictures.  The Pulsar one is good enough to be material for a poster, it is "just right" visually in so many ways!

I got the TIFF function working and did some stacks to reduce noise - it worked, but slow going.

I would love to if I could' as I'm looking enviously everytime you guys are messing around with these TIFF files & radiometric values from your devices, but I'm sadly on an iOS platform that are often quite restricted, and I'm left with the conclusion that all this jazz of thermal information, is simply not processed to these third-party files no matter the preset I choose' when Im on iOS platform.

We also don't have tthe option "to save all data" as far as I can tell.. (screen dump from the Seek iOS menu below, as attachment)
On iOS, you can open the "easter egg" menu, which will give you a live-feed of your current framerate, and some other options like "staging server", and also "simulation mode" (when I asked Seek Thermal support' about some of these extra options, and what they meant & did in practice, they stated it was simply not intended for the end-user, and only for inhouse debugging and would not elevate on their specific purpose)

# Notice for other iOS users, that perhaps are not familiar with this hidden easter-egg menu, you access it by going into [about] and then click like 5 times on the image processing model number. (yep very Android-like  :palm:  though not sure if there is also this hidden menu on Android)

Wow, so you IOS guys are screwed!  Ah, but  you get to see the frame rate instead; lucky you.  I checked & the option on Android is "Save all temperature data" under the main "Preferences" menu.  Maybe that will go away in a while since they don't provide any software to utilize them.

I don't mean to be harshly critical of the Seek cameras; I just don't want someone to think they are better than they really are.  I am mostly content with their performance for my purposes & what I paid for them, partly because I can use my own software. :)  The noise is causing some annoyance with surveillance, though.
I am not opposed to exercise, unless it is an exercise in futility.

So long as we are showing cleanest shots off Seek Pro, here is my ice cream &  cheesecake with me in the background, using my software with a fresh 2-point NUC.  :)  Nearly 60C span.  Unfortunately I don't have that AI sharpening software to clean it up with.  :(

That is pretty clean for a Seek!  -  I guess I'm usually looking at picture with only a few degrees C of contrast, where "something" in the signal path is amping up the gain - which is something that doesn't always have a happy ending with normal light photos either!

I wish it was possible to connect the Seek camera directly to my PC and take pictures from there, instead of being forced to use a mobile device as a step along the way...

Awesome pictures.  The Pulsar one is good enough to be material for a poster, it is "just right" visually in so many ways!

I got the TIFF function working and did some stacks to reduce noise - it worked, but slow going.
Thanks) Draping of clothes looks mesmerizing in lwir, in white hot too, but in rainbow it can look even cooler, if AE algorithm doesnt mess up other details) this file was somehow upscaled, i will attach the original and some more from XP here.
Didnt see that menu item and sold seek android dongles, maybe it was useful) remember when i found folder with files from my first thermal imager, XR-micro usb, they were with 320*240 resolution, i thought my piece had qvga sensor, not 156*206 :D
SilverSolder, this subforum has attached thread about Joec's thermovision, give it a try) i tried it with XR, got a dead pixels map but couldnt improve images, is there any user manual?)) pro model with type с couldnt connect, iphone's needs tricky adapter, still waiting its delivery.

Excactly..its some of the best pictures I could get out of my old Seek Pro I'm uploading here, and some of them have been edited with enhancement to suppress noise, etc.

I have tried to take some of the other pictures on this page and the previous ones from other users Seek XR, Seek Pro, Pulsar, and see how they would look with crude enhancement, just to put it into perspective.
(*I hope it's okay.)

Examples. *original on the left and enhanced on the right. (though all text and numbers, I needed to mask otherwise it would get even more tarnished)

Your people shots are amazing, they would be good as regular photos too...  but the thermal lifts them higher and makes them even more interesting.

What tools do you use for image enhancement / sharpening /denoise - is it all Photoshop or do you also have some AI going on? :D

I love what your enhancements are doing to the images.  Is it a Photoshop plugin or something like that, which you are using here?

I'm quite new to all of Adobe's portfolio of apps, like Premiere and Photoshop, instead been impressed with other programs, from makers like Topaz labs that in the bigger picture are quite crude..
But so far' its been better in achieving details from pictures, than what I'm getting in fx photoshop and some of their Ai-upscaling & detail-enhancement tools.
I tried this program called Gigapixel Ai and was impressed about how it could get details from were there almost was none.

I tested it with one of these 360 cameras, like Insta360 x2.
and it managed from the source material on the left to conclude that there are lines in between those ceramic parts on a streetlamp that were in the picture.
(zoomed way in)
but it is a balancing act to adjust the values, as otherwise, it will eat the details and look like an oilpainting.

It's certainly okay with me; I was hoping you would do that, thank you very much!  :)  :-+

It's a very pronounced improvement on the image with my distinct color palette (3rd sample).

I think this shows that the thing to be learned from these latest posts is not that Seek Pro can make great images but that there is software that can make them great.  So  Topaz Sharpen Ai is what you used to clean up those images?

Thank you) I almost abandoned shooting on regular cameras, thermal is more interesting. But getting normal wide/tele lenses and info on cameras is a big headache. I dont like image editing software, adobe especially. Got a big image/video bundle from topaz on christmas sale, still didnt install it :D photos posted here were only cropped. and forum compresses them, pulsar ones were bit sharper, picture of building with flag is almost pixel-peepingly sharp)
DaneLaw, did you use all 3 topaz pieces - denoise, sharpen and gigapixel? my pictures look like graphic sketches after this enhancement, maybe after some more iterations they will be good enough, i'll try myself someday.

Yeah, Photoshop is sooo big and deep that it takes years to learn to use it fluently...  it is full of "secret handshake" keyboard shortcuts.   It is capable of doing almost anything, though, you can't take away from it that it is an incredibly powerful and capable graphics application that has evolved in the hands of countless professionals over decades.

Seek Thermal Compact : 206 x 156 Thermal Sensor, 36° Field of View (2017 manual focus version)

I've recorded a few angles using a laptop and SeekOFix app (on windows 7). Image quality is better than on the android seek app and fps seems to be a bit higher (14-15 fps).
