Boy, I need some clarification here. I was also under the assumption that
PhotoCal didn't load VLUTs, that the only "calibration" was what you got by
physically adjusting the guns (with PhotoCal's help) and then PhotoCal would
simply create a profile describing this condition with no further
corrections.
PreCal/OptiCal on the other hand let you do the physical adjustment but then
Optical would load VLUTs that *further* corrected the screen display to the
final target settings and then created a profile based on the combined
physical and software adjustments.
Of course, why would PhotoCal ask for a target gamma when it couldn't
actually correct it in the first place using VLUTs? Now I'm really confused!
