what is a cyanotype print
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.n contrast to most historical and present-day processes, cyanotype prints do not react well to basic environments. As a result, it is not advised to store or present the print in chemically buffered museum board, as this makes the image fade.
