I saw some of these prints in person and they were really great. I like their simplicity, and the strange beauty that chemical stains can have, not to mention the wonder it might imbue in people about darkroom photography.
I could photograph the trays probably used by Thomas Joshua Cooper as a student here at HSU (he graduated in 1969) but they would be a bit boring. We have been using the same trays continously in the university darkroom for the 40 years I have been around here -- don't know how far before that they were bought. Stainless steel -- no stains.
At least with LF landscape, a bad day of photography can still be a good day of exercise.
