Daguerreotype to Digital
A Brief History of the Photographic Process
Period of Use: 1840 - 1915
Cyanotypes can be easily identified by their brilliant blue color. Printed on a high grade of paper and lacking in chemical complexity, cyanotypes are very hardy and stable.
Cyanotypes could be easily produced by amateurs at home (exposed to sunlight and washed in rainwater) and were often mounted in albums. The ease of this process caused a wave of popularity at the turn of the century.
