Portfolio > Gum Bichromate Prints

Gum bichromate printing is a 19th-century photographic contact printing process that uses watercolor pigment, gum arabic, and potassium dichromate. Solutions of these three ingredients are combined to make a light-sensitive emulsion which is then brushed in a thin layer onto paper. When the sensitized paper is exposed to ultraviolet light under a photographic negative and developed in water, an image is formed. The image is built up slowly with successive layers through multiple cycles of coating, exposure, and development. The result is a unique handmade print, a fusion of photography and painting, that will last indefinitely and will not fade.

My prints are made on 100-percent cotton paper using the highest-quality pigments. The visible brush marks on the margin of some of the prints are evidence of the hand-printing process and are intentionally displayed as part of the image.
