Cyanotypes (also called sun prints) were the first alternative process that we had to master. Cyanotype is a traditional alternative photographic process that requires treated paper, objects, the sun, and water to produce a cyan-blue print. They are super easy, inexpensive and lots of fun.
Cyanotypy was used in 1843 by photographer Anna Atkins to illustrate the book British Algae: Cyanotype Impressions by Anna Atkins, considered the earliest example of a book illustrated by a purely photographic process. Most of the continuous tone cyanotypes date largely from the period from 1880's to 1920's. They can be found in amateur prints (given the simplicity and non-toxicity of the process) made from 4x5 plates, postcards, studio portraits and as topographical views and novelty subjects.
