This was the daguerreotype process that used iodized silvered plates and was developed with mercury fumes.
Copies were also produced by A well-exposed and sharp large-format daguerreotype is able to faithfully record fine detail at a resolution that today's digital cameras are not able to match.In the early 1840s, two innovations were introduced that dramatically shortened the required exposure times: a lens that produced a much brighter image in the camera, and a modification of the chemistry used to sensitize the plate. Modern photo-historians consider the stories of Daguerre discovering mercury development by accident because of a bowl of mercury left in a cupboard, or, alternatively, a broken thermometer, to be spurious.Another story of a fortunate accident, which modern photo historians are now doubtful about, and was related by Louis Figuier, of a silver spoon lying on an iodized silver plate which left its design on the plate by light perfectly.Daguerre did not give a clear account of his method of discovery and allowed these legends to become current after the secrecy had been lifted.
Abolitionist leader Some of the earliest depictions of African Americans came in the form of slave daguerreotypes taken for Swiss scientist Early 19th century African American photographers such as Augustus Washington and abolitionists such as Frederick Douglass and Dubois presented over 300 photographs (daguerreotypes and others) of African Americans in all facets of existence at his "American Negro Exhibit" at the Although the daguerreotype process is sometimes said to have died out completely in the early 1860s, documentary evidence indicates that some very slight use of it persisted more or less continuously throughout the following 150 years of its supposed extinction.The daguerreotype experienced a minor renaissance in the late 20th century and the process is currently practiced by a handful of enthusiastic devotees; there are thought to be fewer than 100 worldwide (see list of artists on cdags.org in links below). The silver had to be completely free of tarnish or other contamination when it was sensitized, so the daguerreotypist had to perform at least the final portion of the polishing and cleaning operation not too long before use.
It has a mirror-like surface and is very fragile. Even though the portrait was the most popular subject, the daguerreotype was used to record many other images such as topographic and documentary subjects, antiquities, still lives, natural phenomena and remarkable events.View a short movie on the daguerreotype process by the Nederlands Fotomuseum.The video on a complete daguerreotypist set shows an original daguerreotype camera with a lens manufactured by the Parisian optical firm Lerebours et Secretan around 1850.

Withdrawing a protective After development, the light sensitivity of the plate was arrested by removing the unexposed silver halide with a mild solution of Gilding, also called gold toning, was an addition to Daguerre's process introduced by Even when strengthened by gilding, the image surface was still very easily marred and air would tarnish the silver, so the finished plate was bound up with a protective cover glass and sealed with strips of paper soaked in There were two main methods of finishing daguerreotypes for protection and display:
The image, the result of an eight-hour exposure, was the world's first photograph. Since the metal plate is extremely vulnerable, most daguerreotypes are presented in a special housing.
First, recorded information (textual and graphic) could be easily reproduced from film, and,…
This 1848 daguerreotype of Manhattan's Upper West side is the oldest surviving photo of New York. M. de Mandelot himself knows several persons who could subscribe but will not do so because they think it [the secret] would be revealed by itself, and now I have proof that many think in this way.
