This is not necessarily true. Several monitor profiling packages -
ProfileMaker comes to mind but I am sure there are others - build
profiles that have LUT's. So rather than the simplistic matrix
information typical of working space profiles we have the selective
>color correction ability of a table-based profile working for us.
And how do you apply these LUT based monitor profiles??? The Monitors control
panel won't show them as monitor profiles, and therefore Photoshop can't pick
them up as monitor profiles...
Actually I just built myself a new one and was able to see and select
it in the Monitors and ColorSync control panels.
(OS 9.1 and CS 3.0.3)
If you want I'll send it over to you...
using them as LUT based RGB workingspaces
would be possible as of PS6, but thats hardly what we what from a monitor
profile. My point was that no matter how sophistocated a profile we can build
it gets dumbed down to single number gamma curves before it can be applied.
I think that Photoshop used to do this with LUT profiles when you
wanted them to be used as working spaces (simplified monitor RGB) but
AFAIK it uses them in all their LUT glory when applied in transforms
either in convert to profile or in transforms to screen.
