[alt-photo] Colorized VS.using black inks WAS: ICC for Pictorico

[Jeremy Moore]

David,

I used to use colorized negatives with no black ink and when I
switched to using the black inks with QTR in my curve my highlights
were much smoother. I readily admit my QTR profile is much better than
the colorized negative screen/curve I was using before. As to
colorized versus using black inks I don't know if it makes as much of
a difference as having a very fine-tuned shoulder.
