Alex_M Posted April 25, 2019 Share Posted April 25, 2019 I've got a 16-bit ProPhoto document that I want to convert to to 8-bit sRGB. However, when I do this the image changes colors. Why is that? I thought that only Assign ICC Profile changed color. Isn't Convert ICC Profile supposed to keep colors unchanged? Please see attached. Notice the reddish tint of the on with the converted color profile.

v_kyr Posted April 25, 2019 Share Posted April 25, 2019 Well that operation changes gamuts (color spaces), from a very color rich wide gamut like ProPhoto to a much smaller one like sRGB with lesser available colors. There are a lot of colors in ProPhoto which don't have a 1:1 association in sRGB, thus colors can change during this transformation/conversion.

Alex_M Posted April 25, 2019 Author Share Posted April 25, 2019 Oh, I see. Thanks for the clarification! I'll just do some manual retouching until they match then.
