Cyanotypes

A cyanotype is an early photographic process involving chemicals on paper or fabric that produces cyan blue prints. It was discovered by Sir John Herschel in 1842 as a way of reproducing drawings and diagrams such as architectural blueprints. Cyanotypes are a type of contact print which means the actual image being reproduced is placed directly over the paper. You can find out more about the process on the OC&K blog.
