Cyanotypes | Botanical Prints
Cyanotypes are photographic process that produces a "blue print" when you combine potassium ferricyanide and ferric ammonium citrate with water in equal parts. This emulsion is then applied to a water absorbent surface (paper or fabric). Once the surface is dry, it can be exposed by the sun or by a UV light.

The process was discovered by the scientist and astronomer Sir John Herschel in 1842.
