The cyanotype (blueprint) process was used in the Architecture, Engineering, and Construction (AEC) industries before being replaced by what we use in our office today - Autodesk’s AutoCAD.

Cyanotypes are a camera-less alternative photographic process, they are also referred to as 'blueprints' and the word originates from the Greek word Cyan, meaning dark blue impression. It is a non-silver photo printing method that produces a Prussian Blue print.

Architects and Engineers in the 19th and 20th century used the process as a simple and low cost method of reproducing copies of architectural drawings before the invention of photocopier.



The English Scientist, Astronomer and Botanist Sir John Herschel discovered the process in 1942. He was classed as a bit of a scientific superstar of his time. Photography had been discovered about 3 years previously but it was an expensive process. Through his experimentations he developed a process called Cyanotype, the birth of blueprinting. 

It was great to learn this historical process from our industry firsthand and use it to create art.

Thanks to artist Lisa Shepard for running an outstanding 1 day workshop!
