cyanotypes

Blue photographic prints

Cyanotypes are photographic prints made using an iron-based process that produces distinctive blue images.

The technique, developed in the 1840s, involves coating paper with light-sensitive chemicals, placing objects or negatives on the surface, and exposing it to sunlight.

Cyanotypes were used for architectural blueprints before becoming popular as an artistic medium: She made cyanotypes of pressed flowers from her garden.
