The cyanotype process was one of the first non-silver technologies used to create photographic images. Originated in the 1840’s, it was not utilized in mainstream photography and was adopted as a copying technique, becoming known by the term “blueprint”, with its blue background reproductions of large architectural and mechanical drawings.

Unlike photographs set in silver, like in black and white photography, cyanotypes are using a solution of iron compounds. The photograph can be taken with a camera, like a digital camera, and the resulting photo turned into a negative that can be used to make a cyanotype. The basic cyanotype recipe has not changed very much since Sir John Herschel introduced it in 1842. To begin the process, two solutions are prepared for the two-part sensitizing process. Material sensitized with the solution is then printed by ultraviolet light.
