[excerpts from wikipedia]

Tintype, also melainotype and ferrotype, is a photograph made by creating a direct positive on a sheet of iron metal that is blackened by painting, laquering or enamelling and is used as a support for a collodion photographic emulsion.

Photographers usually worked outside at fairs, carnivals etc. and as the support of the tintype (there is no actual tin used) is resilient and does not need drying, instant photographs can be produced only a few minutes after taking the photograph.

An ambrotype uses the same process and methods on a sheet of glass that is mounted in acase with a black backing so the underexposed negative image appears as a positive.Tintypes did not need mounting in a case and were not as delicate as photographs that used glass for the support.

While the ambrotype remained very popular in the rest of the world, the tintype process had superseded the ambrotype in the United States by the end of the Civil War. It became the most common photographic process until the introduction of modern, gelatin-based processes and the invention of the reloadable amateur camera by the Kodak company. Ferrotypes had waned in popularity by the end of the 19th century, although a few makers were still around as late as the 1950s and the images are still made as novelties at some European carnivals.
