Lindbloom suggests that only developers could use his Lab-Lab profile. I
believe him because I can't find anything, outside of the OS 10
ColorSync Utility, that will open his L-L profile.
Gustav Braun and Mark Fairchild wrote a paper on this topic - check
google for "Color Gamut Mapping in a Hue-Linearized CIELAB Color Space".
All the work on color appearance spaces addresses this issue, amongst
others. Various reports about CIACAM97 and CIECAM02 cover this as well.
Is any developer considering making use of this Lab-Lab conversion
process? If they did, they would solve most of the problems which force
me to proof and reproof, over and over, depending on how many of the
issue noted above the particular image contains.
As a developer, I don't have a need to use this approach, since I'm doing
my gamut mapping in a color appearance space rather than L*a*b*.
