Large and rare Ferrotype
Portrait of a woman with earrings
Format 17.5 x 24.5 cm
The ferrotype, also called tintype or melainotype, is an old photographic process that involves sensitizing a metal plate by applying a varnish and a collodion emulsion. The image obtained after exposure and development is a negative. It appears positive thanks to its dark background. The ferrotype is a unique print.
Invented around 1852 by Adolphe-Alexandre MARTIN, this process was patented in the United States, where it enjoyed great success between 1860 and 1890. It then replaced the daguerreotype and the ambrotype due to its more affordable cost, simplicity and speed of execution.
