So, since everyone seems aware that CIELAB makes a less than optimal PCS,
why aren't we changing it? Could individual software manufacturers employ
any PCS they wish, or is using CIELAB part and parcel of the ICC spec? What
are the politics here?
I know CIECAM97 is a ways away, but what are other candidates for a PCS?
In the ICC spec, LUT-based profiles must use D50 LAB as PCS, and
matrix profiles must use XYZ.
LAB has its warts, but it's not at all clear that there's a better
candidate waiting in the wings. Implementing CIECAM is going to be
quite, er, challenging...
