      Tri-Color Gum Printing Lecture with Diana Bloomfield

      In this intensive two-day workshop, we will learn how to print in the 19th century photographic process of gum bichromate. Using color separation negatives, we’ll learn how to make multilayered, tri-color gum bichromate prints on watercolor paper.

      After mixing an emulsion of watercolor pigment, potassium dichromate, and gum arabic, this mixture is brushed on watercolor paper, dried, and by placing a negative on top it is exposed to UV light.

      We then ‘develop’ the prints in plain tap water. Layers are built by repeated coatings and careful registration of negatives until a full, rich image is achieved.

      We will also explore one-coat, monochrome prints, made using black and white negatives.

      To kick off the workshop weekend, Diana H. Bloomfield will be giving a lecture on Friday, May 17 from 7-8pm. Join us to hear her speak about her artwork and working methods and get a preview of the gum bichromate process before the workshop!
