Cyanotype is one of the oldest photographic processes we know of, and has a distinctive blue color. Cyanotypes are made by treating a surface — paper or fabric — with iron salts which then react to UV light. Originally used to document botanical specimens by placing them on treated papers and exposing them to the sun, it was also an early way to create copies of drawings – thus the name “blueprints.”
