Cyanotype

Cyanotype

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: ammonium iron(III) citrate and potassium ferricyanide.

I created my own cyanotype using secondary images which I cut up a reorganised. I used a picture of a cassette tape, a cactus and a dot pattern. I found that the lighter the image, the better the results.
