It's dispiriting to see how inflexible, parochial and blinkered companies
and standards bodies can prove to be. Was it truly a question of *whether*
CIECAM is going to appear in color management technologies? Was it ever less
than a matter of *when*?
Like Roger, I do not claim to understand CIECAMs deeply, but just enough to
know that they will be used at some point in the future, possibly the near
future (see the example of WCS), and will contribute a great deal to
improved results by dealing with aspects of color appearance that a simply
colorimetric model cannot cope with effectively (simultaneous contrast,
spreading, crispening, and other visual phenomena listed in chapter 6 of
Mark Fairchild's "Color Appearance Models").
Based on what I read above, Apple, the ICC, etc., seem unable to learn that
success *for everyone* in color management only comes from agreement and
standardization, and that proprietary systems set us all back.
This is all very foolish...
