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:

Although I've posted this elsewhere on the site in answer to another question, I think this is just about pretty enough to qualify for the gallery:

It's a simple electric wall heater, taken with a ThermApp Pro and ThermViewer, but with the palette messed about with in Paint Shop Pro X. I like the rather psychedelic result.

What imaging setup did you use?

elninjo888 · « **Reply #254 on:** November 22, 2018, 11:17:35 am »

Super resolution is on,
first picture - enhanced pallet is on,
second picture - image enhancement with sharpening edges,
third - non,
fourth - non

I am using Xtherm T3s camera.

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?!

Subject 1: Teensy 3.2 on a small DIY board (my 'Blackbody' controller)
Subject 2: 1 Euro coin
Camera: TE-V1
Lens 1: 14.25mm f/1.2 (teensy close up and coins)
Lens 2: 35mm f/1.4 (teensy far)
Postprocessing: non (linear mapping to gray scale for the teensy / the coins are logarithmically mapped to gray scale)

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.

That looks nice - and Waifu2x has done a good job. Try starting the heater from cold and taking images as it heats up - you can get some interesting heat distribution patterns.

Will do that but I must first upgrade my custom software to enable locked thermal range on sequence of images.

Seek Thermal PRO FF, somewhere around 16-17HZ, but feels like a little less...

Dark Volter · « **Reply #268 on:** January 18, 2019, 05:40:24 am »

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 see there is some kind of export feature implemented in ThermApp android app:

If somebody sends me this exported files I can take a look at it and maybe implement conversion to different palettes into my free app:

Ultrapurple · « **Reply #271 on:** January 18, 2019, 09:11:05 am »

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.

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.

How do you do the larger images? Do you automate that in some way?
