Cyanotype is one of the oldest photographic processes, discovered in 1842 by the scientist Sir John Herschel. It’s a simple and toxic-free technique that produces a beautiful Prussian Blue print using a photosensitive solution. After arranging the plants (or objects) on the coated surface, exposing them under the sun, and then rinsing under water... magic happens! What you're left with is a beautiful print that is as unique as Nature itself!
