Autographic
From Wikipedia, the free encyclopedia
The Autographic system for roll film was launched by Kodak in 1914, and allowed the photographer to add written information on the film at the time of exposure.
The system was patented by Henry Jacques Gaisman, inventor and safety razor manufacturer. George Eastman purchased the rights for US$300,000. It consisted of a tissue-like carbon paper sandwiched between the film and the paper backing. Text was entered using a metal stylus, and would appear in the margin of the processed print. The system was never very popular, and was discontinued in 1932.
Kodak's Autographic films have "A" as the first part of the film size designation. Thus, standard 127 film would be labeled "127" and Autographic 127 would be "A127".
