BTSALP Specialists gathered at Luminaria Photography Studio on Saturday, September 8, 2018 to learn the process of Cyanotype. This 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. Thanks to Dave Hyams & Christine Baczek.
The English scientist and astronomer Sir John Herschel discovered the procedure in 1842. Though the process was developed by Herschel, he considered it as mainly a means of reproducing notes and diagrams, as in blueprints.
