About The Photographic Process: The CYANOTYPE, or "blueprint" photographic process, is one of several alternative photographic methods based on the light sensitivity. The Prussian blue color is achieved much like a blueprint. It dates to the early origins of Photography, were this sun-process was used to create a permanent archival photographic print in the mid-Nineteenth Century. The English astronomer, Sir John Herschel, is credited with inventing the cyanotype in 1842. Cyanotypes were popular as an efficient and cost effective way of reproducing drawings before the relatively recent invention of mechanized photocopying methods. Hence working copies of building plans became known as blueprints. Cyanotype chemistry relies on two distinct reactions: ferric ions in an organic-iron complex is reduced by light to form ferrous ions, which in turn reacts with potassium ferricyanide to form an insoluble blue compound called Turnbull's blue. Turnbull's blue is actually the same as Prussian blue, a commonly used pigment in artists' paints. The net result is that Prussian blue is formed on the paper to fix the image. As an alternative photographic process, the Cyanotype is experiencing a renaissance, as contemporary photographers go back to unique printing techniques to create unmatched images in Contemporary Photography.
