There are a few advanced features in OptiCal that PhotoCal lacks, and I
believe that the current versions still read different data sets, but thats
about all thats fundamentally different; PhotoCal definately lets you select
a white point and gamma (from two choices each, rather than OptiCal's wide
range of choices), define a black point (visually as opposed to OptiCal's
colorimeter read black point) and build a profile using those choices, on top
of your gun precalibration.
