Yes, you use libraw to download raw images and libraw has a list of cameras it supports. Topaz Photo AI can load any dng file, but if the camera is not supported, color shifting happens. After talking to libraw tech support, they gave me some advice on this. Quote: “color shift occurs” - please use the color matrix the DNG contains. For DNG files, matrices in LibRaw are only fallbacks. So the color shift problem can be solved by reading the dng color matrix data. There is a question of correction of photo optics, but it is not so difficult, it can be corrected manually in the editors. The only pressing issue is the color shift, which will take quite a long time to correct.
Thank you for your attention.
