I'm an idiot. The question re: percpetual rendering of an "in-gamut" image
should have read:
<snip>
What happens to "Image B", my totally in-gamut image:
(the question:) Perceptual: What happens here? Does A) all the colors
*still* get compressed because there's no mechanism for it deduce that all
the colors are in-gamut so no compression is necessary AND it has to assume
that their are colors stretching to the outer edges of the RGB WS or... B)
the colors don't get compressed as it somehow "knows" that this iamge is
in-gamut and doesn't require compression?
In other words, if you have RGB WS "A" and CMYK WS "B" and CMM "C", every
image, regardless of content or gamut, gets "compressed" exactly the same
way? Or not?
Question 2: in a RelCol gamut compression, I *assume* that as colors get
closer to the outer edge of the color gamut, the amount of compression or
"scaling" that takes place actually *increases* relative to colors that are
farther away from the perimeter of the color gamut. True?

Sorry for the waste in bandwidth...
