About the Course
Gum bichromate is a highly versatile hand-made photo process that encourages creative image making. Using medium/large format negatives, students practice mixing and applying emulsions, image exposure and development. Creative controls such as color choices, selective development, and multiple printing will be covered. Digital negatives can be made if needed. More info: gummist@gmail.com. Minimum age 16.

Mac Cosgrove-Davies
Mac teaches Historic Photo Processes at Photoworks.
These processes include:
gum bichromate, cyanotype, VanDyke, palladium, and carbon printing.
In addition to building the occasional camera, printing frame or other useful photographic gadget, he also creates books and presentation portfolios for his prints.
He is currently working on hand painted cyanotypes.
Mac is inspired by the work of Gertrude Kasebier and Edward Steichen
"I focus on my student’s interests. My classes are less about showing how I make prints and more about helping students make the prints they want to make."
