cyanotype

Sun-printed blue image

A cyanotype is a photographic printing process that produces distinctive blue-and-white images.

The process uses iron compounds that turn deep Prussian blue when exposed to ultraviolet light, typically sunlight.

Cyanotypes were historically used for reproducing architectural and engineering drawings—the original blueprints.

The technique remains popular among artists and photographers for its handmade aesthetic: She made cyanotype prints of pressed ferns.
