1. Ambrotype

   The ambrotype (from Ancient Greek: ἀμβροτός — “immortal”, and τύπος — “impression”) also known as a collodion positive in the UK, is a positive photograph on glass made by a variant of the wet plate collodion process. Like a print on paper, it is viewed by reflected light. Like the daguerreotype, which it replaced, and like the prints produced by a Polaroid camera, each is a unique original that could only be duplicated by using a camera to copy it. The ambrotype was introduced in the 1850s. During the 1860s it was superseded by the tintype, a similar photograph on thin black-lacquered iron, hard to distinguish from an ambrotype if under glass.

1. Ambrotype

   The ambrotype or amphitype is a photograph that creates a positive image on a sheet of glass using the wet plate collodion process. In the United States, ambrotypes first came into use in the early 1850s. The wet plate collodion process was invented just a few years before that by Frederick Scott Archer, but ambrotypes used the plate image as a positive, instead of a negative. In 1854, James Ambrose Cutting of Boston took out several patents relating to the process and may be responsible for coining the term "ambrotype". In the United Kingdom it was called collodion positive: one side of a very clean glass plate is covered with a thin layer of collodion, then dipped in a silver nitrate solution. The plate is exposed to the subject while still wet. The plate is then developed and fixed. The resulting negative, when viewed by reflected light against a black background, appears to be a positive image: the clear areas look black, and the exposed, opaque areas appear light. This effect is achieved by coating one side of the glass negative with black varnish. Either the emulsion side or the blank side can be covered with the varnish: when the blank side is blackened, the thickness of the glass adds a sense of depth to the image. In either case, another plate of glass is put over the fragile emulsion side to protect it, and the whole is mounted in a metal frame and kept in a protective case. In some instances the protective glass was cemented directly to the emulsion, generally with a balsam resin. This protected the image well but tended to make it darker.
