Description
An inexpensive positive photograph made using a collodion emulsion on a black enameled Tinplate. The process for making tintype, or ferrotype, photographs was patented in 1856 and used up to the 1940s. Tintype plates contained a thin layer of photoreactive Collodion coated on a black lacquered iron sheet. They produced a direct positive image that was processed quickly and inexpensive. The images often had poor contrast levels ranging from a dull grays to creamy whites. Tintypes were typically pasted in paper cards with decorative embossed borders. They were called ferrotypes outside the USA.
Synonyms and Related Terms
