Amazing Tri-Color Gum & Cyanotype 
with Christina Z. Anderson

Gum prints are essentially photographically controlled watercolor prints made in a 19th century process called gum bichromate. Gum Arabic is mixed with watercolor paint and photosensitive ammonium dichromate, and painted onto paper. When exposed to light in contact with an enlarged negative, the gum Arabic hardens into an image that is “developed” in plain water. 

Cyanotype or the “blueprint” process is probably one of the most well-known 19th century processes ever. It is an easy process to learn and perfect in combination with tricolor gum.

 The workshop will center on simple digital negatives, so a laptop with Photoshop, Photoshop Elements, or Lightroom plus rudimentary knowledge of one of these programs (for example, sizing, sharpening, cropping images, even maybe knowing how to add a curve) is important. So is bringing lots of color digital images to choose from. Aside from a few simple supplies from home (teaspoons, hair dryer, towel, apron, and the like) the rest of the supplies will be covered under a class fee, including multiple pigment colors with which to experiment.

 Participants tend to work from 9AM–9PM, with some early birds and night owls working longer. By the time the workshop ends, all should be comfortable with these processes to hit the ground running when returning home.
