Cyanotype is one of the oldest photographic techniques.
The printing process - popular in Victorian England, where it was created in 1842 - uses UV light to produce what are known as “sun prints” in a dark greenish-blue.
Carmen Joyce - a self-taught artist and photographer - will teach the process in a “Printing with Light” class - Saturday at 10 AM at Crabtree Farms here in Chattanooga.
