Tri-Color Gum Bichromate Printing, Cullowhee Mountain Arts!
Join me for a week-long tri-color gum bichroamte workshop at Cullowhee Mountain Arts, on the campus of Western University, in Cullowhee, North Carolina. The workshop runs from June 25-30, 2017. Check it out!
Come and visit the beautiful NC mountains learning how to print in the 19th century photographic process of gum bichromate. Using color separation negatives (made via 21st century technology), we will learn how to make multi-layered, tricolor gum bichromate prints on watercolor paper. A specific emulsion of watercolor pigment, potassium dichromate, and gum arabic is carefully brushed on watercolor paper. After drying, a digital negative is placed on top, exposed to UV light, and then “developed” in plain tap water. With repeated coatings and careful negative registration, layers are slowly built until a rich color image is achieved . . .
