[Photo] Develop persona opens DNG files with wrong colors

Recommended Posts

I use Topaz Jpeg to Raw AI to convert JPGs to 16-bit DNG files. I noticed that Photo 1.6.5.123 and the latest beta of Photo (1.7.0.293) open the DNG files with wrong colors. Why is that? Adobe Camera Raw opens them with correct colors. Please see attached some screenshots along with the original JPG image I used to convert to DNG with Topaz Jpeg to Raw AI.

It is attached in my original post just above the DNG. Does it not come up?

I have been investigating this and the outputted DNG colours can change as the conversion is to a liner dng file format more information regarding this can be found in the link below

To keep the colours closer to the jpg file you can convert it to an tif file

Thanks for the tip. Will I get the same range of colors and dynamic range with TIF though? DNG images created by JPEG to RAW AI are 32-bit color depth while TIFs are 16-bit. Also, why doesn't Affinity Photo read these DNGs similar to Adobe Camera RAW? Adobe Camera RAW seems to read the colors very close to the original JPG. :35_thinking:

If you're starting with JPEG, what color depth are you starting with?
