Gum bichromate, an alternative photographic process, involves using a light-sensitive emulsion made of gum arabic, potassium bichromate, and pigment. The emulsion is applied to a paper or other substrate, exposed to UV light through a negative, and then developed by washing away the unexposed areas with water. This process can be repeated with different colors and layers to create multi-layered, hand-painted-like prints. Gum bichromate prints are characterized by their painterly quality, soft focus, and the ability to create unique, textured images. The process offers artists the opportunity to blend photography and painting, resulting in highly expressive and artistic prints.
