In Photoshop 6, sometimes, I get different results
when I apply a profile or convert to a profile-same
image, same profile. I appreciate any feedback on this
matter.
A file is just a bunch of RGB, CMYK or grayscale numbers, with no
fixed colorimetric interpretation. (Ask a roomful of people to think
of "red" and you'll get a lot of different reds.)
Applying a profile attaches a specific colorimetric meaning to the
numbers in the file. The numbers don't change, but the appearance
does. For example, Adobe RGB has a much larger gamut than sRGB, so if
you take an Adobe RGB image and apply the sRGB profile, it will
appear more saturated, even though the numbers in the file haven't
changed.
But if you convert the image from Adobe RGB to sRGB, the appearance
won't change much, if at all (the out of gamut colors will change
more than the others), but the numbers in the file will change a lot.
Does that help?
