Collodion Chloride Printing Out Paper (POP)
This is my favorite silver process because of all the variation I can get with toning. I took a workshop at the George Eastman House with Mark Osterman.
I can print by inspection which allows me to really dial in the exposure time.
I can make the emulsion myself. Recipe is fairly simple.
Toning is made either with gold or platinum solutions. The concentrations are pretty small which also makes the prints very archival.
Exposure times are between five and fifteen minutes (depending on the negative density)
