TINTYPES
Tintype, properly known as ferrotype, is a photograph made by creating a direct positive on a sheet of iron metal that is blackened by painting, lacquering, or enamelling and is used as a support for a collodion photographic emulsion, which is a light sensitive silver mixture.
The technical details of it is when a photographic negative image on a film or a plate is very underexposed, it appears as a positive when viewed against a dark background.
Tintypes had one of the longest periods of popularity of any early photograph type, lasting from 1850-1930. This process was first described by Adolphe-Alexandre Martin in France in 1853 and patented in the U.S. on Feb. 19, 1856 by Hamilton Smith.
The three main advantages of the tin type were threefold: 1. very durable, 2. inexpensive, and 3. it was the first truly instant photograph.

Great images - be careful about cutting and pasting text from wikipedia - I would rather you use your own words, even if they are a little awkward, than have you lift text from another article.
