Similar cameras were used for exposing the silver-surfaced copper Daguerreotype plates, commercially introduced in 1839, which were the first practical photographic medium.

The collodion wet plate process that gradually replaced the Daguerreotype during the 1850s required photographers to coat and sensitize thin glass or iron plates shortly before use and expose them in the camera while still wet.

Early wet plate cameras were very simple and little different from Daguerreotype cameras, but more sophisticated designs eventually appeared.

Towards the end of his undergraduate degree he became a contributor to the Westminster Review with his first article entitled " Electrotype and Daguerreotype ," published in September 1840.

Not long after the introduction of the Daguerreotype in 1839, photographers began assembling multiple images of a view into a single wide image.

Niépce died suddenly in 1833, but Daguerre continued experimenting and evolved the process which would subsequently be known as the Daguerreotype.

The images were enthusiastically praised as nearly miraculous and news of the Daguerreotype quickly spread.

For the process which was eventually named the Daguerreotype, he exposed a thin silver-plated copper sheet to the vapor given off by iodine crystals, producing a coating of light-sensitive silver iodide on the surface.

The latent image on a Daguerreotype plate was developed by subjecting it to the vapor given off by mercury heated to 75 ° Celsius.

The Daguerreotype was the Polaroid film of its day: it produced a unique image which could only be duplicated by using a camera to photograph the original.

The paper-based calotype process, introduced by Henry Fox Talbot in 1841, allowed the production of an unlimited number of copies by simple contact printing, but it had its own shortcomings — the grain of the paper was obtrusively visible in the image and the extremely fine detail of which the Daguerreotype was capable was not possible.

The introduction of the wet collodion process in the early 1850s provided the basis for a negative-positive print-making process not subject to these limitations, although it, like the Daguerreotype, was initially used to produce one-of-a-kind images — ambrotypes on glass and tintypes on black-lacquered iron sheets — rather than prints on paper.

A true Daguerreotype is always an image on a highly polished silver surface, usually under protective glass.

If it is viewed while a brightly lit sheet of white paper is held so as to be seen reflected in its mirror-like metal surface, the Daguerreotype image will appear as a relatively faint negative — its dark and light areas reversed — instead of a normal positive.

Like a sensitized Daguerreotype plate, but unlike Talbot's earlier " sensitive paper ", better known as " salted paper ", the calotype paper had to be exposed in the camera only long enough to produce a very faint or completely invisible image which was then chemically developed to full visibility.

This inhibited the widespread adoption of the calotype process as an alternative to the Daguerreotype in the UK.
