Cyanotype is a photographic printing process that produces a cyan-blue print. Engineers used the process well into the 20th century as a simple and low-cost process to produce copies of drawings, referred to as blueprints. The process uses two chemicals: ferric ammonium citrate and potassium ferricyanide.

The result created by the cyanotype chemicals plus the process of solar development is often a surprise
and that’s one of the attractions for me. I love to experiment.
