One and one only





I have many dreams i want to accomplish in my life and one of them,
is to be the owner of an original tintype photograph. I love them.
The whole process and the result is just the old time thing i like to have.
A memory from the past.
The most amazing thing about them is that, there is no negative.
This is the only one photo, there isn't an other copy and i believe that makes
them even more great, that uniqueness!!





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, lacquering 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, photographs can be produced only a few minutes after the picture is taken.
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. Tintypes did not need mounting in a case and were not as delicate as photographs that used glass for the support.

History

The process was first described by Adolphe-Alexandre Martin in France in 1853, patented in 1856 both in the United States by Hamilton Smith and William Kloen in the United Kingdom. It was first called melainotype, then ferrotype by a rival manufacturer of the iron plates used; finally tintype.

Ambrotype

The ambrotype was the first wet-plate collodion process, invented by Frederick Scott Archer in 1851 and introduced in the United States by James Ambrose Cutting in 1854.

Success of the tintype

While the ambrotype remained very popular in the rest of the world, the tintype process had superseded the ambrotype in the United States by the end of the Civil War.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.

Advantages of the tintype

The tintype was a minor improvement to the ambrotype, replacing the glass plate of the original process with a thin piece of black-enameled, or japanned, iron (hence ferro). The new materials reduced costs considerably; and the image, in gelatin-silver emulsion on the varnished surface, has proven to be very durable. Like that of the ambrotype, the tintype's image is technically negative; but, because of the black background, it appears as a positive. Since the tintype 'film' was the same as the final print, most tintype images appear reversed (left to right) from reality. Some cameras were fitted with mirrors or a 45-degree prism to reverse (and thus correct) the image, while some photographers would photograph the reversed tintype to produce a properly oriented image.
Tintypes are simple and fast to prepare, compared to other early photographic techniques. A photographer could prepare, expose, develop, and varnish a tintype plate in a few minutes, quickly having it ready for a customer. Earlier tintypes were often cased, as were daguerreotypes and ambrotypes; but uncased images in paper black sleeves and for albums were popular from the beginning.

  1. I love old pictures, they are so unique. Digital cameras are very helpful these days and without them we would not be able for example to write our blogs ;), but I can imagine how precious pictures used to be, just one chance, one picture. Sometimes I wish I could travel in time :) Everyone wishes for that sometimes I guess.
