The Cyanotypes Process
Cyanotype is the photographic printing process discovered by Sir John Herschel, a polymath scientist, in 1842 as a means to reproduce multiple diagrams. It creates a cyan blue silhouette when an object is placed on a reactive surface and developed in UV light – a blue print. Modern cyanotypes processes include the use of digitally produced UV blocking negatives giving a more nuanced (tonal) image. Each cyanotype is unique as each print is handmade and some are hand tinted.
