Gum Bichromate over Palladium

Gum bichromate is essentially watercolor painting with photographic tools. These images are a version of CMYK printing in which a K layer (the palladium image) is overlayed with successive layers of colored gum. I use anywhere from 1 to 4 successive layers of colored gum to obtain the effect I want. It often takes an entire day to make one of these prints and they are one of a kind. I could not go back and exactly duplicate one of them, even if I tried.
