I beg to differ. Colorcheckers have been known to vary considerably,
the only way to really know what one has is to dig out a spectro and
measure.
BTW, weren't you the one, Robin, who said that the original
Colorchecker is actually more useful than the SG because it is based
on more pigments? I wonder how many base pigments are used for the
Passport?
