Looked at http://www.imagemagick.org/Usage/formats/#color_profile and am not 100% sure I got the full picture.
If the profile is embedded in InputImage, is
Code: Select all
convert InputImage -profile (stuff I want to do in linear RGB) OutputImage
I don't particulary care which linear RGB I'm getting (meaning I don't care what the primaries are; I'd actually be OK working in another linear light space, like XYZ) as long as I can do "stuff" in something that approximates linear light, and as long as I can start and return to Adobe RGB without losing too many bits. It's really important that if "(stuff I want to do in linear RGB)" is basically a no-op in disguise, then the input and output colors match in Adobe RGB.
