This was originally a digital shot, printed as a casein bichromate on six layers of glass – about 30 hours of work, including the dozens of layers that I printed and discarded. The final print is just over half an inch thick.

During the process of making this print, I’ve cataloged about 20 different variables that are affecting the print quality of each individual layer. The most pernicious so far: potassium dichromate in suspension instead of solution, crystallizing on the plates before exposure. Time to switch to ammonium dichromate, which has a higher saturation point.
