ambrotype

By the late 1850s faster and less expensive processes such as the ambrotype, became available.

He began with the ambrotype, which preceded the daguereotype in 1849.

The ambrotype was the first use of the wet-plate collodion process as a positive image.

This experimentation began after seeing a 19th-century ambrotype of a woman and her ex-lover who had been scratched from the frame.

He later developed the ambrotype jointly with Peter Fry.

Freeman worked in the ambrotype process.

Within a few years, Ukai managed to produce over two hundred ambrotype portraits of members of the aristocracy.

Though they were of poorer quality than the contemporary ambrotype, they were very popular with street photographers and produced in great quantity.

The ambrotype, using collodium to produce a positive image on glass, and the pannotype, also collodium-based, were both used in Denmark from around 1855.

This process also produced positives, the ambrotype and the tintype (also known as ferrotype).

The tintype or ferrotype, introduced in 1856; an image like the ambrotype, but on a thin blackened iron plate instead of glass.

The intricate, complex, labor-intensive daguerreotype process itself helped contribute to the rapid move to the ambrotype and tintype.

The ambrotype was much less expensive to produce than the daguerreotype, and it lacked the daguerreotype's shiny metallic surface, which some found unappealing.

By one of those paradoxes of light, if it is underexposed and backed by a dark surface, the image reads as a positive - an ambrotype.

Like that of the ambrotype, the tintype's image can be thought of as a negative; but, because of the black background, it appears as a positive.

The ambrotype of three children belonged to Amos Humiston of Portville, New York.

The tintype can be seen as a modification of the earlier ambrotype, replacing the glass plate with a thin sheet of japanned iron (hence ferro).

In 1854, James Ambrose Cutting of Boston took out several patents relating to the process and may be responsible for coining the term "ambrotype".

The ambrotype, introduced in 1854; a negative image on glass which appeared positive when on dark "ruby" glass or backed with a black varnish or cloth.

Then came the ambrotype, which is a kind of daguerreotype except that it involves a negative coated with collodion, which becomes a positive when laid on a dark ground.

A large image (4x5 inch 3/4 thick) called a 1/4 plate ambrotype in full union case by Littlefield and Parsons Daguerreotypes Case Makers.

An ambrotype uses the same process and methods on a sheet of glass that is mounted in a case with a black backing so the underexposed negative image appears as a positive.

A rare surviving example of a large format Ambrotype portrait of the Burrells is featured, that was taken in 1857, six years after they settled at Arthur's Seat.

Opalotype is one of a number of early photographic techniques now generally consigned to historical status, including ambrotype, autochrome, cyanotype, daguerrotype, ivorytype, kallitype, orotone, and tintype.

To create an ambrotype, the photographer sensitized a polished plate of glass by the wet plate collodion process and exposed the plate in a camera to produce a negative image.
