Hi Roger,
I suspect, to really do a good job of gamut mapping, you would not
want to have a "global" approach but a "selective", "local"
approach? If 100 means all farben kompressed, surely all colors
could not be compressed the *same*? Or uniformly? Across all hue
angles?
I would imagine that depends exactly upon whether or not the strategy
of a PRMG or alternatively of output profiling for a specified working
space is applied.
If it is not applied, the profiler has no choice (at least
theoretically) but to compress all Lab colors "uniformly" in the sense
that any possible Lab color must be mapped (not clipped) to the target
space in the 100 setting.
If, OTOH, one of the above strategies is applied, then of course the
mapping should relate to the specified working space or medium gamut.
I.e. if this gamut contains e.g. highly saturated blues more than it
contains highly saturated reds or greens, but the target gamut does
not, then of course (I think ...) the blues would be compressed more.
But that's only what I'm guessing since it seems logical ...
Bye
Uli
