Well, if I read into PhotoGamut correctly, this is more than a working
space. This is akin to a "printer" or "output-referred" space (like ROMM and
RIMM RGB). So, if tonal relationships are altered for some divine reasons by
the designers of that space then it needs to be examined on the basis of its
merits -- I wouldn't be prepared to dismiss it on the face value. I'd ask
the question first: does it actually result in more pleasing or
"perceptually-correct" tone mapping as opposed to transitionning tones
through a straight matrix shaper space?

OK. So your view on this concur with the authors, wouldn't you say?

I agree with you that there are many profiling packages whose perceptual
tables aren't that different to their relative tables, if that's what you're
referring to?

It's easy to say everything is subjective -- I don't mean that derogatively,
please rest assured. But that's a frequent comment. Over and above
subjectivity, there exists some sound and basic color reproduction ideas
that have not changed much over time. I was alluded to correctness of hue in
an earlier post, as an example. If PhotoGamut does meet some of thse
universally agreed upon old repro ideas (read before ColorSync and the ICC
-- and soon WCS!), I think it has merit as not being just a cold, synthetic
space to convert colors into but something that has some enhanced color
imaging ideas, just like Joe Holmes "chroma variants". Although, please
don't quote me as trying to compare or contrast the two.
What do you think?
