Wikipedia Overview
Kallitype is a process for making photographic prints. Patented in 1889 by W. W. J. Nicol (1855–1929), the kallitype print is an iron-silver process. A chemical process similar to the Van Dyke brown based on the use of a combination of ferric and silver salts. While Van Dyke brown and argyrotype use ferric ammonium citrate, the light-sensitive element used for the kallitype is ferric oxalate. The use of ferric oxalate allows for both extended shadow definition and contrast control.
