Ferrotypes (also known in the USA as Tintypes) are photographs made onto black-enamelled iron plates by the wet-collodion process. The black background made the transparent areas of the negative image appear black, and the dark, silvered areas were whitened using mercuric bichloride, and so appear light - in the same way as glass Ambrotypes.
French photographer Adolphe A Martin was the first to use this process, in 1853. A dry ferrotype processes later replaced the wet-plate system. As the process could be carried out inside the camera (or in an attached developing tank) and needed no drying time, dry ferrotypes were popular with "while-you-wait" beach and street photographers[1]. Some cameras were advertised specifically for this purpose, such as the Mandel-ette. It was also attractive that the plates were very much cheaper than those for Daguerrotype.
Since the image must be viewed from the silvered side of (non-transparent!) plate, the image is left-right reversed (mirror-imaged) - a feature shared with Daguerreotypes.
The process was used in the US until the early 1940s.
Many ferrotype cameras are essentially box cameras, with an attched developing tank. Some have a bellows or focusing lens. There are also cameras by several makers of a 'cannon' design. These are usually for very small 'button' plates. Other tintype cameras cover formats at least up to postcard size.
