Digital BW, The Print

This isn't a color Group, of course...but I'm glad to see SOMEBODY
still has some visual knowledge of color, doesn't have to rely on the
crutches of measuring devices! Visual skills in color and zone theory
seem to be drifting into "lost art" category.

IMO a person who can't describe a color shift in terms of CCs
(standard color compensation units) is flying blind. I'm probably
flying blind myself, in my zone system sloppiness.
