Just get the cheapest used macro lens you can find, and then the cheapest used matching camera. Results will be way better for a given light then any phone on the market. The lower the light, the way betterer it gets. |

I assume the algorithm used by the software on my computer is more efficient than what the camera uses, so it could even be better, although I doubt it would be noticeable. So the only limiting factors are in the hardware, which is going to be the same in either case. --- End quote --- Maybe things would be different if you use the camera vendor's raw software (if available), but having played with two different 3rd party raw processor I can tell you straight away that in many ways, the results will depend more on the raw software used than on the camera. There is a lot of processing and secret sauce going into generation of a viewable image from the raw sensor data. For starters, as I hinted before, the uncompressed image you get from this process is actually up to 3x larger than the raw data, go figure ::) Raw has surprisingly little to do with the final image. Almost every image you see on the Internet, including professional photos, is JPEG. If you have ever seen any good looking images on the Internet, you have seen good looking JPEGs. Raw's utility (if any) is not as much in avoiding JPEG artifacts, as in gaining more control over things like color rendition and white balance, tonality, sharpening or noise reduction. Or outright processing the image beyond recognition for some supposed artistic value. Occasionally, rescuing images which had been destroyed by bad camera settings during shooting. If you start reading on the topic, you will find rants by professionals who bluntly say they have no time to mess with that stuff and would rather buy a camera which can be tweaked to produce the images they want right off the bat :P |

Such a shame, the covid app would take the best pictures of PCBs in the world :D |

Good hijack Dave. :clap: @magic I am just guessing here, I have zero experience with anything more than point and shoot.I used to mess around with 3D stuff, but that was mostly modeling, not much rendering. That is about as close as it gets. Even if I do nothing, it is nice to have the option. I picked up the XTi today and it saves both at the same time, so that is nice too. The camera looks good. Cannot say much else about it until I learn to use it. I did manage to take a crappy picture of my bird though. Hopefully during the week I can figure out what most of the settings do and how to get to them. |
