Re: gum curves

David,
I am as ill equipped to explain this as you, so I think you need to have
some other computer techie or Mark Nelson explain, but when I make my color
choice it eliminates that variable to two strains. In other words, no black
ink used in my negs, and in the colored ones, only 2 of the three strains,
too, even. For the black ink only, I just check in my Epson 2200 "black ink
only". So they aren't greyscale negs but really black only. But let those
better than I explain how this be so.

It's kinda sad; the print I am working on is a print of a little place in
Bayou le Batre, AL (of Forrest Gump fame) that I took this June when driving
thru the deep South. Bet it's not there anymore after Katrina.
