A type of photograph invented by Louis Daguerre in 1839.

The first practical photographic process announced in 1839 by Louis Jacques Mande Daguerre, was popular from the early 1840s until the late 1850s. A daguerreotype is aunique image on metal produced by treating a copper plate with a light-sensitized surface coating of silver iodide. A daguerreotype is distinctive for its highly polished silver support and its quality of appearing either as a negative or positive, depending on the angle and light from which it is viewed. Daguerreotypes are light-sensitive and fragile, and are usually stored in cases for protection.

A direct-positive process, creating a highly detailed image on a sheet of copper plated with a thin coat of silver without the use of a negative.

One of the earliest photographic techniques that yielded a single tarnish-like image on a shiny silver plate.

the world's first practical photographic process, announced by Jacques Daguerre in 1839. Daguerreotypes were produced on silver-coated copper plates and usually housed in protective leather or plastic cases. None of the images on "Baltimore City Nineteenth-Century Photos" are daguerreotypes. Only in rare instance is the photography studio identified on a daguerreotype. Rarer still, is the daguerreotype that contains the name of the subject.

was the first successful photographic process. Its principal inventor was Louis Daguerre, in 1839, although several others contributed significant ideas, foremost among whom was Joseph Niépce who had produced crude images in the 1820s on pewter coated with pale colored bitumen. A daguerreotype is often a sharp image, but as there is no negative, additional prints could not be made from it.

The earliest form of permanent photographic imaging. Or, perhaps the earliest widely accepted form. Exposures were made on polished copper plates, coated with sensitized silver. Obviously named after Louis Daguerre.

A direct positive process where the image was created by the action of light on copper plate coated with polished silver and developed in mercury vapour, invented by Louis Daguerre in 1839.

An image formed on a sheet of copper plated with silver and sensitized by iodide vapors. Highly vulnerable to physical damage and tarnishing they were normally protected by a metal mat and a covering sheet of glass. The image is on a highly polished plate, and to be seen must be held at an angle to minimize reflections. (Baldwin, 35)

A direct positive process in which a silvered copper plate was made sensitive to light by fuming in iodine vapour. After exposure the latent image was made visible by the fumes of warmed mercury. Invented by L.J.M. Daguerre, it was revealed to the public 19 August 1839, and remained immensely popular through the 1850s, especially for use by professional portrait photographers. For an account of this process see M. Susan Barger and W.B. White The Daguerreotype, (Baltimore: Johns Hopkins University Press, 1991). Exhibits created using this process

Early photographic process which used iodine-sensitized silver plate and mercury vapour.

photographic process invented by L. J. M. Daguerre (1789-1857), a French painter, in which pictures were reproduced on silver plates by sensitizing them with iodine and then developing them with mercury

A plate of copper, lightly coated with silver. After cleaning and polishing the plate, exposure to iodine vapors created a light-sensitive surface that looked like a mirror. The plate, held in a lightproof holder, was then transferred to the camera and exposed to light. The plate was developed over hot mercury until an image appeared. To fix the image, the plate was immersed in a solution of sodium thiosulfate or salt and then toned with gold chloride.

An image formed on a silver-coated copper plate, sensitized by fumes of iodine. The image is developed in mercury vapor, which produces a unique direct positive image. Introduced in 1839 by Louis-Jacques-Mandé Daguerre, who had developed this process after his partnership with Joseph Nicéphore Niépce. This process was widely used until 1860.

photograph on silver-coated copper plate; pioneering process, popular in America, 1840-60

Invented by Louis Jacques Mandé Daguerre and announced in 1839, this was the first process to take advantage of a latent image. A silver-plated sheet of copper was sensitised with the fumes of chlorine or bromine and exposed in the camera. When developed over the fumes of mercury, an amalgam was formed on the silver surface. Once fixed, this could be viewed by reflecting light off the plate. The unique image was structurally a negative but appeared to be positive in the right light.

This, the first published photographic process, was invented by Louis J. M. Daguerre in France in 1839. It soon became the most popular medium in the mid 19th century, producing a unique and permanent direct positive image on a copper plate without the use of a negative. The plate was exposed in the camera for as long as 20 minutes in daylight, which required the sitter to remain very still for long periods of time. The silver surface has a mirror-like shine and, being fragile, were often placed into a special viewing case; sizes vary but are measured from double whole plate (8 x 13 inches) to sixteenth plate (1 5/8 to 2 1/8 inches) with the sixth plate the most common (2 x 3 inches). The daguerreotype process was eventually replaced by the wet collodian process in the 1850s.

Named after one of the pioneers of photography (Louis Daguerre, 1787-1851) this process was common from the early 1840s until approximately 1860. The photograph consists of a positive image on a highly polished silver surface, with a thin copper plate underneath. When viewed from different angles the image appears as either a positive or a negative.

A positive image on a copper plate coated with silver. The daguerreotype must be held at an angle that does not reflect bright light in order to view the image. This was the first type of imaging process to become popular worldwide.

A photographic process in which a positive image formed by mercury vapour is produced on a copper plate coated with a highly-polished layer of silver. The daguerreotype has a mirror-like surface and is usually in its own decorative and protective case. Popular from 1839 to the 1860s.

Photo process developed by Joseph Daguerre that produces an extremely grainy, gray or sepia-toned (brownish) image; presently used to artificially convey age.

The first practical photographic process, in which an image is formed on a copper plate coated with highly polished silver that is sensitized by fumes of iodine to form silver iodide. Following exposure the latent image is developed in mercury vapor, resulting in a unique image on metal that cannot be used as a negative for replication. Return to Photographs

A Daguerreotype is a photograph taken by the method published by Louis J. M. Daguerre in France in 1839. It is a positive image formed by mercury vapor on a polished coating of silver on a copper plate. The highlights of the Daguerreotype consist of a milky deposit of mercury amalgam and the shadows of plain polished silver. The plate was exposed in the camera for as long as twenty minutes in daylight which explains the often stiff posture of the sitter. Further, the Daguerreotype camera produced an image that was reversed right to left unless the lens was equipped with a reversing mirror. Each Daguerreotype is unique and is permanent. This along with its early date in photographic history, accounts for its desirability as a collectible. Portraits are relatively common while outdoor scenes are rare. The larger full-plate Daguerreotypes were more expensive to make as well as to but at the time, and therefore are scarcer today than smaller Daguerreotypes. The making of Daguerreotypes went out of fashion after the introduction od the wet collodion process of the 1850's.

Made public in 1839, this was the first published photographic process and one of the most popular mediums in the mid 19th century, producing a unique direct positive image on a copper plate without the use of a negative; the silver surface has a mirror-like shine and, being fragile, are usually fitted into a special viewing case; sizes vary but are measured from double whole plate (8 x 13 inches) to sixteenth plate (1 5/8 to 2 1/8 inches) with the sixth plate the most common (2 x 3 inches).

An early photographic process (invented in 1839) where the impression made on a light-sensitive silver-coated metal plate is developed by mercury vapor. Each is an original since no duplication process exists.

Daguerreotype is an early photographic process. It depended on long exposure time and bright light and was recorded on a silver plate. It was invented by Louis Jacques Mandé Daguerre in 1837. Close

The first practical photo process invented in 1838 in which an image was formed on a copper plate coated with highly polished silver. Following exposure, the image is developed in mercury vapor, resulting in a unique image on metal that cannot be used as a negative for replication.

first practical and commercial photographic process, introduced by Louis Daguerre in 1839. The sensitive material comprised silver iodide, deposited on a polished silver plated copper base. A positive image was produced by camera exposure and mercury "development", which turned light struck halides gray-white. The image was made permanent by immersing the plate in a solution of sodium chloride.

The daguerreotype is an early type of photograph in which the image is exposed directly onto a mirror-polished surface of silver bearing a coating of silver halide particles deposited by iodine vapor. In later developments bromine and chlorine vapors were also used, resulting in shorter exposure times. Unlike later photographic processes that supplanted it, the daguerreotype is a direct positive image making process with no "negative" original.
