Siderotype is an iron-based photographic print. The term was coined by Sir John Frederick William Herschel. A short list of processes defined as siderotypes is as follows: amphitype, argentotype, argyrotype

Argyrotype

Argyrotype is an iron-based silver printing process that produces brown images on plain paper. It is an alternative process derived from the Argentotype, Kallitype, and Van Dyke processes of the 19th Century, but has greater simplicity, improved image stability, and longer sensitizer shelf-life...

Cyanotype

Cyanotype is a photographic printing process that gives a cyan-blue print. The process was popular in engineering circles well into the 20th century. The simple and low-cost process enabled them to produce large-scale copies of their work, referred to as blueprints...

Kallitype

Kallitype is a process for making photographic prints.Patented in 1889 by W. W. J. Nicol, 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. Many developing solutions can be used to give a...

Platinotype

Platinum prints, also called platinotypes, are photographic prints made by a monochrome printing process that provides the greatest tonal range of any printing method using chemical development....

Van Dyke Brown is an early photographic printing process. The process was so named due to the similarity of the print color to that of a brown oil paint named for Flemish painter Van Dyck.-Printing:...
