Tintype
A tintype, also known as a melainotype or ferrotype, is a photograph made by creating a direct positive on a thin sheet of metal coated with a dark lacquer or enamel and used as the support for the photographic emulsion. Tintypes enjoyed their widest use during the 1860s and 1870s, but lesser use of the medium persisted into the early 20th century and it has been revived as a novelty and fine art form in the 21st. Tintype portraits were at first usually made in a formal photographic studio, like daguerreotypes and other early types of photographs, but later they were most commonly made by photographers working in booths or the open air at fairs and carnivals, as well as by itinerant sidewalk photographers. Because the lacquered iron support (there is no actual tin used) was resilient and did not need drying, a tintype could be photographic processing, developed and fixed and handed to the customer only a few minutes after the picture had been taken.

Collodion Process
The collodion process is an early photographic process. The collodion process, mostly synonymous with the "collodion wet plate process", requires the photographic material to be coated, sensitized, exposed, and developed within the span of about fifteen minutes, necessitating a portable darkroom for use in the field. Collodion is normally used in its wet form, but it can also be used in dry form, at the cost of greatly increased exposure time. The increased exposure time made the dry form unsuitable for the usual portraiture work of most professional photographers of the 19th century. The use of the dry form was therefore mostly confined to landscape photography and other special applications where minutes-long exposure times were tolerable. History Gustave Le Gray first theorized about the collodion process, publishing a method in 1850 that was "theoretical at best", but Frederick Scott Archer was credited with the invention of the process, which he created in 1848 and publis ...

Photographic Emulsion
Photographic emulsion is a light-sensitive colloid used in film-based photography. Most commonly, in silver-gelatin photography, it consists of silver halide crystals dispersed in gelatin. The emulsion is usually coated onto a substrate of glass, films (of cellulose nitrate, cellulose acetate or polyester), paper, or fabric. Photographic emulsion is not a true emulsion, but a suspension of solid particles (silver halide) in a fluid (gelatin in solution). However, the word ''emulsion'' is customarily used in a photographic context. Gelatin or gum arabic layers sensitized with dichromate used in the dichromated colloid processes carbon and gum bichromate are sometimes called ''emulsions''. Some processes do not have emulsions, such as platinum, cyanotype, salted paper, or kallitype. Components Photographic emulsion is a fine suspension of insoluble light-sensitive crystals in a colloid sol, usually consisting of gelatin. The light-sensitive component is one or a mixture o ...

Daguerreotype
Daguerreotype (; french: daguerréotype) was the first publicly available photographic process; it was widely used during the 1840s and 1850s. "Daguerreotype" also refers to an image created through this process. Invented by Louis Daguerre and introduced worldwide in 1839, the daguerreotype was almost completely superseded by 1860 with new, less expensive processes, such as ambrotype ( collodion process), that yield more readily viewable images. There has been a revival of the daguerreotype since the late 20th century by a small number of photographers interested in making artistic use of early photographic processes. To make the image, a daguerreotypist polished a sheet of silver-plated copper to a mirror finish; treated it with fumes that made its surface light-sensitive; exposed it in a camera for as long as was judged to be necessary, which could be as little as a few seconds for brightly sunlit subjects or much longer with less intense lighting; made the resulting lat ...

Ambrotype
The ambrotype (from grc, ἀμβροτός — “immortal”, and — “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. Process One side of a clean glass plate was coated with a thin layer of iodized collodion, then dipped in a silver nitrate solution. The plate was exposed in the camera while still wet. Exposure times varied from five to sixty seconds or more depending on the brightness of the lighting and the speed of the camera len ...

James Ambrose Cutting
James Ambrose Cutting (1814–1867) was an American photographer and inventor, sometimes called the inventor of the Ambrotype photographic process. He grew up in poverty on a farm in Haverhill, New Hampshire. At age 28, he invented a new type of beehive in 1842, and on the money from selling his patents moved to Boston, Massachusetts. Ambrotypes 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. The wet plate collodion process was invented just a few years before by Frederick Scott Archer and widely used for glass negatives, but in an ambrotype the collodion image is used as a positive, instead of a negative. When dry, the glass plate was then backed either with black paint, metal, cloth, or paper; this black backing made light areas of the negative appear darker, turning the negative image into a positive. Some ambrotypes were made with ruby or dark green ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

Japanned
Japanning is a type of finish that originated as a European imitation of East Asian lacquerwork. It was first used on furniture, but was later much used on small items in metal. The word originated in the 17th century. American work, with the exception of the carriage and early automobile industries, is more often called toleware. It is distinct from true East Asian lacquer, which is made by coating objects with a preparation based on the dried sap of the ''Toxicodendron vernicifluum'' tree, which was not available in Europe. Japanning is most often a heavy black "lacquer", almost like enamel paint. Black is common and japanning is often assumed to be synonymous with black japanning. The European technique uses varnishes that have a resin base, similar to shellac, applied in heat-dried layers which are then polished, to give a smooth glossy finish. It can also come in reds, greens and blues. Originating in India, China and Japan as a decorative coating for pottery, authenti ...

Photographic Fixer
Photographic fixer is a mix of chemicals used in the final step in the photographic processing of film or paper. The fixer stabilises the image, removing the unexposed silver halide remaining on the photographic film or photographic paper, leaving behind the reduced metallic silver that forms the image. By fixation, the film or paper is insensitive to further action by light. Without fixing, the remaining silver halide would darken and cause fogging of the image. Fixation is commonly achieved by treating the film or paper with a solution of thiosulfate salt. Popular salts are sodium thiosulfate—commonly called hypo—and ammonium thiosulfate—commonly used in modern rapid fixer formulae. Fixation involves these chemical reactions (X = halide, typically Br−):Karlheinz Keller et al.

Frederick Scott Archer
] Frederick Scott Archer (1813 – 1 May 1857) was an English photographer and sculptor who is best known for having invented the photographic collodion process which preceded the modern gelatin emulsion. He was born in either Bishop's Stortford or Hertford, within the county of Hertfordshire, England (United Kingdom of Great Britain and Ireland) and is remembered mainly for this single achievement which greatly increased the accessibility of photography for the general public. Life Scott Archer was the second son of a butcher in Bishops Stortford in Hertfordshire who went to London to take an apprenticeship as a goldsmith and silversmith with a Mr Massey of 116 Leadenhall Street. On the recommendation of Edward Hawkins he trained at the Royal Academy Schools a sculptor and found calotype photography useful as a way of capturing images of his sculptures. Dissatisfied with the poor definition and contrast of the calotype and the long exposures needed, Scott Archer invented the ...
