What "original"? The AdobeRGB image file, which only exists in electronic
format?
Its viewing condition is D50, 2-degree CIE 1931 Standard Observer, as is
that of the converted image.
What happened to standard viewing conditions in a color-correct (D50)
viewing booth of standard illuminance? Now we must be converting for CIECAM
too? This is getting stranger and stranger.
A good thing only if one doesn't work in imaging production, and can afford
endless theoretical speculations in place of producing viable results. I
can't imagine how one would ever get anything done, when one throws a
million variables at the problem, each of which changes everything.
As for Fairchild's book, I have it, I have read enough to understand the
gist of it, and I also have met Mark in person.
