Platinum printing is a technique that was widely used in the late 1800's for its relative ease and unbeatable tonal range. However, in the 1920's, photographers such as Alfred Stieglitz and Edward Steichen began using this method for the handmade nature that allowed the photographer to be like a painter, and manipulate the image in ways that were not possible before.
These prints combine light sensitive iron salts, and the salts of heavy metals platinum and palladium. After mixing these solutions in a shot glass, I coat the paper by hand and make a contact print, exposing the light sensitive paper to ultra-violet rays. Prints are then developed in potassium oxalate and are cleared and washed thoroughly for maximum archivability.
