Re: yet another 2 cents on" Food for thought"

Hello Gordon, You can most certainly do this with gum and a computer to
generate the negs. But, if you want to stay in the darkroom (as opposed to
digital lightroom), shoot transparencies, then enlarge these onto multiple
B&W sheet films in your darkroom. Then tape the (identical) negs to a
bright window and paint out the areas you don't want to print with Kodak
Opaque or similar product. Use your choice of registration methods and
print away in an assortment of realistic colors (or not!).

I did a series like this (with, he says quietly, a lens camera) a few years
back. You can see some on my webpage (see signature). Go to the fine art
page, then the "downtown portfolio". Good luck.
