Just received a PM that was sent weeks ago about color profiles. So here's a quick how-to on how to set up color profiles in Photoshop and manually install missing profiles.
How to manually install color profiles like ProPhoto for Photoshop or system-wide (refers to Windows XP, but 7 should be pretty much the same):
* download ProPhoto color profile file (*.icm or *.icc file), for instance from here:
* extract file from zip archive, copy to
c😛rogram FilesCommon FilesAdobeColorProfiles
(I use the latter location)
* restart Photoshop.
To check if an image tool supports the specific color profile, compare the image visually to the same image in a web browser (modern browsers can deal with color profiles, while image browsers, well...it depends).
Configure Photoshop so that it leaves embedded profiles intact:
* Color settings > "Color management policies" to "Preserve embedded profiles"
and displays a warning if the profile isn't available:
* Color settings > "Color management policies/missing profiles", check "Ask when opening"
