timeline 1894-1920

Description: A non-silver printing method using paper coated with a solution of gum arabic containing potassium or ammonium bichromate to make it light sensitive, and a pigment to provide image tones. This process allows extensive physical manipulation of the image by the photographer, sometimes resulting in an image which looks more like a drawing or watercolor painting than a photograph.
