Historic Photography: Cyanotype

Today Harrison will be demonstrating the cyanotype process which was invented in the 1840s and produces blue-tinted prints. In the 1870s, architects began using the process to reproduce blueprints, and it’s where we get the term from. In the 1880s, photographers started using the process as a cheap way of “proofing” their prints before doing final prints, which used more expensive chemicals containing silver and platinum.
