During the past few decades, there has been a small revival of daguerreotypy among photographers interested in making artistic use of early photographic processes. To make the image, a daguerreotypist would polish a sheet of silver plated copper to a mirror finish, treat it with fumes that made its surface light sensitive, expose 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 make the resulting latent image on it visible by fuming it with mercury vapor remove its sensitivity to light by liquid chemical treatment, rinse and dry it, then seal the easily marred result behind glass in a protective enclosure. The image is on a mirror like silver surface, normally kept under glass, and will appear either positive or negative, depending on the angle at which it is viewed, how it is lit and whether a light or dark background is being reflected in the metal.

The surface is very delicate, and even the lightest wiping can permanently scuff it. Some tarnish around the edges is normal. Several types of antique photographs, most often ambrotypes and tintypes, but sometimes even old prints on paper, are very commonly misidentified as daguerreotypes, especially if they are in the small, ornamented cases in which daguerreotypes made in the US and UK were usually housed. The name daguerreotype correctly refers only to one very specific image type and medium, the product of a process that was in wide use only from the early 1. Historyedit. Camera obscura, from a manuscript of military designs. Italian. Since the Renaissance era, artists and inventors had searched for a mechanical method of capturing visual scenes. Using the camera obscura, artists would manually trace what they saw, or use the optical image in the camera as a basis for solving the problems of perspective and parallax, and deciding color values. The camera obscuras optical reduction of a real scene in three dimensional space to a flat rendition in two dimensions influenced western art, so that at one point, it was thought that images based on optical geometry perspective belonged to a more advanced civilization. Later, with the advent of Modernism, the absence of perspective in oriental art from China, Japan and in Persian miniatures was revalued. In the early seventeenth century, the Italian physician and chemist Angelo Sala wrote that powdered silver nitrate was blackened by the sun, but did not find any practical application of the phenomenon. The discovery and commercial availability of the halides iodine, bromine and chlorine a few years earlier iodine was discovered by Courtois in 1. Lwig in 1. 82. 5 and Balard in 1. Scheele in 1. 77. The daguerreotype is one of these processes, but was not the first, as Nipce had experimented with paper silver chloride negatives while Wedgwoods experiments were with silver nitrate as were Schultzes stencils of letters. Hippolyte Bayard had been persuaded by Arago to wait before making his paper process public.

Joseph Nipces bitumen based heliography in 1. The first reliably documented attempt to capture the image formed in a camera obscura was made by Thomas Wedgwood as early as the 1. Sir Humphry Davy The images formed by means of a camera obscura have been found too faint to produce, in any moderate time, an effect upon the nitrate of silver. To copy these images was the first object of Mr. Wedgwood in his researches on the subject, and for this purpose he first used the nitrate of silver, which was mentioned to him by a friend, as a substance very sensible to the influence of light but all his numerous experiments as to their primary end proved unsuccessful. Development in FranceeditIn 1. French artist and chemist. Louis Jacques Mand Daguerre, when obtaining a camera obscura for his work on theatrical scene painting from the optician Chevalier, was put into contact with Nicphore Nipce, who had already managed to make a record of an image from a camera obscura using the process he invented heliography. Daguerre met with Nipce and entered into correspondence with him. Nipce had invented an early internal combustion engine the Pyrolophore together with his brother Claude and made improvements to the velocipede, as well as experimenting with lithography and related processes. Their correspondence reveals that Nipce was at first reluctant to divulge any details of his work with photographic images. To guard against letting any secrets out before the invention had been improved, they used a numerical code for security. Nipce physautotype glass original accidentally destroyed circa 1. The written contract drawn up between Nicphore Nipce and Daguerre 2. Nipce to release details of the process he had invented the asphalt process or heliography. Daguerre was sworn to secrecy under penalty of damages, and undertook to design a camera and improve the process. The improved process was eventually named the physautotype. Nipces early experiments had derived from his interest in lithography and centered around capturing the image in a camera then called a camera obscura to result in an engraving that could be printed somehow by lithography. The asphalt process, or heliography required exposures that were so long that Arago said it was not fit for use. Nevertheless, without Nipces experiments, it is unlikely that Daguerre would have been able to build on them to adapt and improve what turned out to be the daguerreotype process. After Nipces death in 1. Isidore, inherited rights in the contract and a new version was drawn up between Daguerre and Isidore. Isidore signed the document admitting that the old process had been improved to the limits that were possible and that a new process that would bear Daguerres name alone was sixty to eighty times as rapid as the old asphalt bitumen one his father had invented. It would bear Daguerres name alone. This was the daguerreotype process that used iodized silvered plates and was developed with mercury fumes. To exploit the invention four hundred shares would be on offer for a thousand francs each, secrecy would be lifted after a hundred shares had been sold. Or, the rights of the process could be bought for twenty thousand francs. Daguerre wrote to Isidore Niepce on 2 January 1. Arago He sees difficulty with this proceeding by subscription it is almost certain just as I myself have been convinced ever since looking on my first specimens that subscription would not serve. Everyone says it is superb but it will cost us the thousand francs before we learn it the process and be able to judge if it could remain secret. 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. I entirely agree with the idea of M. Arago, that is get the government to purchase this discovery, and that he himself would pursue this in the chambre. I have already seen several deputies who are of the same opinion and would give support this way it seems to me to have the most chance of success thus, my dear friend, I think it is the best option, and everything makes me think we will not regret it.
