Argyrotype
The photographic process of the argyrotype is a further development of the calotype , the oldest negative-positive process, carried out by Mike Ware in 1991 . In contrast to the calotype, a large-format sheet film negative or a photo plate is not used as a template.
The Englishman William Henry Fox Talbot registered a patent for the process in 1841 under the term “ calotype ” (hence it is also known as “talbotype”; for the historical process see there). The calotype was the first method by which an image could be reproduced repeatedly. The other process available at the time, the daguerreotype , only allowed the production of unique specimens without a negative.
The fine printing process still used today , the argyrotype, developed from these foundations . Complete kits consisting of a ready-to-use solution and special paper are available from specialist retailers. The photographer can coat this paper with the solution and let it dry in order to expose, water and fix the negative in the contact frame in the sun. The brownish photos can then be tinted.
