Alt Process Introduction 9 Classes: June 7, 8, 9, 14, 15, 16, 21, 22, 23 10:00am–2:00pm This 3-week class is for those with an interest in photography’s earliest printing processes and their modern variations. We will cover the following: • Cyanotype— an iron-based process discovered in 1842 that yields blue images. • Kallitype— a late 19th century iron-silver process that can produce prints ranging from sepia to brown to black. • Salted Paper Prints— these prints are based on the process announced by William Henry Fox Talbot in 1839. • Albumen Prints— process in which egg whites are used to bind the light-sensitive chemicals to the paper. The dominant print process of the latter half of the 1800s. • Gum Bichromate— gum arabic, dichromates, and pigments offer the possibility of full-color prints. Class participants will be given full access to our facilities—darkroom, alternative process equipment, finishing area, digital print station, and lighting studio—during and outside of class hours. We have a refrigerator and microwave/toaster oven, so feel free to bring a lunch. There are also numerous restaurants close by. Course fee includes chemistry, an initial supply of paper and film for contact negatives, and most sundry materials. Participants will be given a list of additional required and recommended supplies prior to the first class, as well as information on how to prepare yourself for the first class. Participants are asked to wear old clothing and comfortable shoes. The only prerequisites are a desire to learn, experiment, and have fun.
