The darkest areas of the image are simply bare silver; lighter areas have a microscopically fine light-scattering texture. The surface is very delicate, and even the lightest wiping can permanently scuff it. Some <a href="/wiki/Tarnish" title="Tarnish">tarnish</a> around the edges is normal. </p><p>Several types of antique photographs, most often ambrotypes and <a href="/wiki/Tintype" title="Tintype">tintypes</a>, but sometimes even old prints on paper, are commonly misidentified as daguerreotypes, especially if they are in the small, ornamented cases in which daguerreotypes made in the US and the 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 1840s to the late 1850s. </p> <div id="toc"

Niépce's reputation as the real inventor of photography became known through his son Isidore's indignation that his father's early experiments had been overlooked or ignored although Nicéphore had revealed his process, which, at the time, was secret. </p><p>The phrase <i>the birth of photography</i> has been used by different authors to mean different things – either the publicizing of the process (in 1839) as a metaphor to indicate that previous to that the daguerreotype process had been kept secret; or, the date the first photograph was taken by or with a camera (using the asphalt process or heliography), thought to have been 1822, but Eder's research indicates that the date was more probably 1826 or later.<sup id="cite_ref-54" class="reference"><a href="#cite_note-54"><span class="cite-bracket">[</span>50<span class="cite-bracket">]</span></a></sup> Fox Talbot's first photographs, on the other hand, were made "in the brilliant summer of 1835."<sup id="cite_ref-55" class="reference"><a href="#cite_note-55"><span class="cite-bracket">[</span>51<span class="cite-bracket">]</span></a></sup> </p><p>Daguerre and Niépce had together signed a good agreement in which remuneration for the invention would be paid for by subscription. However, the campaign they launched to finance the invention failed. François Arago, whose views on the system of patenting inventions can be gathered from speeches he made later in the House of Deputies (he apparently thought the English patent system had advantages over the French one) did not think the idea of raising money by subscription to be a good one, and supported Daguerre by arranging for motions to be passed in both Houses of the French parliament. </p><p>Daguerre did not patent and profit from his invention in the usual way.

The government would then present the daguerreotype process "free to the world" as a gift, which it did on 19 August 1839.

Usually the silver is a thin layer on a copper substrate, but other metals such as brass can be used for the substrate and daguerreotypes can also be made on solid silver sheets. A surface of very pure silver is preferable, but sterling (92.5% pure) or US coin (90% pure) or even lower grades of silver are functional. In 19th century practice, the usual stock material, <a href="/wiki/Sheffield_plate" class="mw-redirect" title="Sheffield plate">Sheffield plate</a>, was produced by a process sometimes called plating by fusion. A sheet of sterling silver was heat-fused onto the top of a thick copper ingot. When the ingot was repeatedly rolled under pressure to produce thin sheets, the relative thicknesses of the two layers of metal remained constant. The alternative was to <a href="/wiki/Electroplating" title="Electroplating">electroplate</a> a layer of pure silver onto a bare copper sheet. The two technologies were sometimes combined, the Sheffield plate being given a finishing coat of pure silver by electroplating. </p><p>In order that the corners of the plate would not tear the buffing material when the plate was polished, the edges of the plate were bent back using patented devices that could also serve as plate holders to avoid touching the surface of the plate during processing.<sup id="cite_ref-69" class="reference"><a href="#cite_note-69"><span class="cite-bracket">[</span>65<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-70" class="reference"><a href="#cite_note-70"><span class="cite-bracket">[</span>66<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading4"><h4 id="Polishing">Polishing</h4><span class="mw-editsection"> <a role="button" href="/w/index.php?title=Daguerreotype&amp;action=edit&amp;section=7" title="Edit section: Polishing" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> <span class="minerva-icon minerva-icon--edit"></span> <span>edit</span> </a> </span> </div> <p>To optimize the image quality of the end product, the silver side of the plate had to be polished to as nearly perfect a mirror finish as possible.

Becquerel daguerreotypes, when fully developed and fixed, typically take on a somewhat bluish hue.

The cameras were fitted with Chevalier <a href="/wiki/Camera_lens#Early_photographic_camera_lenses" title="Camera lens">lenses</a> which were "<a href="/wiki/Lens_speed" title="Lens speed">slow</a>" (about <a href="/wiki/F-number" title="F-number">f/14</a>).<sup id="cite_ref-91" class="reference"><a href="#cite_note-91"><span class="cite-bracket">[</span>note 5<span class="cite-bracket">]</span></a></sup> They projected a sharp and undistorted but dim image onto the plate. Such a lens was necessary in order to produce the highly detailed results which had elicited so much astonishment and praise when daguerreotypes were first exhibited, results which the purchasers of daguerreotype equipment expected to achieve. Using this lens and the original sensitizing method, an exposure of several minutes was required to photograph even a very brightly sunlit scene. A much "faster" lens could have been provided—simply omitting the integral fixed <a href="/wiki/Diaphragm_(optics)" title="Diaphragm (optics)">diaphragm</a> from the Chevalier lens would have increased its working aperture to about <a href="/wiki/F-number" title="F-number">f/4.7</a> and reduced the exposure time by nearly 90 percent—but because of the existing state of lens design the much shorter exposure would have been at the cost of a peripherally distorted and very much less clear image. With uncommon exceptions, daguerreotypes made before 1841 were of static subjects such as landscapes, buildings, monuments, statuary, and <a href="/wiki/Still_life_photography" title="Still life photography">still life</a> arrangements. Attempts at <a href="/wiki/Portrait_photography" title="Portrait photography">portrait photography</a> with the Chevalier lens required the sitter to face into the sun for several minutes while trying to remain motionless and look pleasant, usually producing repulsive and unflattering results. The Woolcott mirror lens that produced tiny, postage stamp size daguerreotypes made portraiture with the daguerreotype process possible and these were the first photographic portraits to be produced. In 1841, the <a href="/wiki/Petzval_lens" title="Petzval lens">Petzval Portrait Lens</a> was introduced.<sup id="cite_ref-92" class="reference"><a href="#cite_note-92"><span class="cite-bracket">[</span>87<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-93" class="reference"><a href="#cite_note-93"><span class="cite-bracket">[</span>88<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-94" class="reference"><a href="#cite_note-94"><span class="cite-bracket">[</span>89<span class="cite-bracket">]</span></a></sup> Professor <a href="/wiki/Andreas_von_Ettingshausen" title="Andreas von Ettingshausen">Andreas von Ettingshausen</a> brought the need for a faster lens for daguerreotype cameras to his colleague, Professor Petzval's attention, who went ahead in cooperation with the <a href="/wiki/Voigtl%C3%A4nder" title="Voigtländer">Voigtländer</a> firm to design a lens that would reduce the time needed to expose daguerreotype plates for portraiture. Petzval was not aware of the scale of his invention at the start of his work on the lens, and later regretted not having secured his rights by obtaining letters patent on his invention. It was the first lens to be designed using mathematical computation, and a team of mathematicians whose specialty was in fact calculating the trajectories of ballistics was put at Petzval's disposal by the <a href="/wiki/Archduke_Louis_of_Austria" title="Archduke Louis of Austria">Archduke Ludwig</a>. It was scientifically designed and optimized for its purpose. With a working aperture of about <a href="/wiki/F-number" title="F-number">f/3.6</a>, an exposure only about one-fifteenth as long as that required when using a Chevalier lens was sufficient. Although it produced an acceptably sharp image in the central area of the plate, where the sitter's face was likely to be, the image quality dropped off toward the edges, so for this and other reasons it was unsuitable for landscape photography and not a general replacement for Chevalier-type lenses. Petzval intended his lens to be convertible with two alternative rear components: one for portraiture and the other for landscape and architecture.<sup id="cite_ref-95" class="reference"><a href="#cite_note-95"><span class="cite-bracket">[</span>90<span class="cite-bracket">]</span></a></sup></p><figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Gezicht_op_de_Predikherenlei_en_-brug_te_Gent,_ca._1839,_STAM_Gent.tif" class="mw-file-description"><noscript><img src="//upload.wikimedia.org/wikipedia/commons/thumb/a/a4/Gezicht_op_de_Predikherenlei_en_-brug_te_Gent%2C_ca._1839%2C_STAM_Gent.tif/lossy-page1-220px-Gezicht_op_de_Predikherenlei_en_-brug_te_Gent%2C_ca._1839%2C_STAM_Gent.tif.jpg" decoding="async" width="220" height="163" class="mw-file-element" data-file-width="5165" data-file-height="3835"></noscript><span class="lazy-image-placeholder" style="width: 220px;height: 163px;" data-src="//upload.wikimedia.org/wikipedia/commons/thumb/a/a4/Gezicht_op_de_Predikherenlei_en_-brug_te_Gent%2C_ca._1839%2C_STAM_Gent.tif/lossy-page1-220px-Gezicht_op_de_Predikherenlei_en_-brug_te_Gent%2C_ca._1839%2C_STAM_Gent.tif.jpg" data-width="220" data-height="163" data-srcset="//upload.wikimedia.org/wikipedia/commons/thumb/a/a4/Gezicht_op_de_Predikherenlei_en_-brug_te_Gent%2C_ca._1839%2C_STAM_Gent.tif/lossy-page1-330px-Gezicht_op_de_Predikherenlei_en_-brug_te_Gent%2C_ca._1839%2C_STAM_Gent.tif.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/a/a4/Gezicht_op_de_Predikherenlei_en_-brug_te_Gent%2C_ca._1839%2C_STAM_Gent.tif/lossy-page1-440px-Gezicht_op_de_Predikherenlei_en_-brug_te_Gent%2C_ca._1839%2C_STAM_Gent.tif.jpg 2x" data-class="mw-file-element">&nbsp;</span></a><figcaption>‘View of the Predikherenlei and Predikherenbrug’ depicts the first photographic record of <a href="/wiki/Ghent" title="Ghent">Ghent</a> and in all probability <a href="/wiki/Belgium" title="Belgium">Belgium</a>.

Salomon,<sup id="cite_ref-158" class="reference"><a href="#cite_note-158"><span class="cite-bracket">[</span>153<span class="cite-bracket">]</span></a></sup> and <a href="/wiki/Chuck_Close" title="Chuck Close">Chuck Close</a> have reintroduced the medium to the broader art world. The use of electronic flash in modern daguerreotype has solved many of the problems connected with the slow speed of the process when using daylight. </p><p>International group exhibitions of contemporary daguerreotypists' works have been held, notably the 2009 exhibition in Bry Sur Marne, France, with 182 daguerreotypes by forty-four artists, and the 2013 ImageObject exhibition in New York City, showcasing seventy-five works by thirty-three artists. The <a href="/wiki/Astolat_Dollhouse_Castle" title="Astolat Dollhouse Castle">Astolat Dollhouse Castle</a> also displays daguerreotypes. The appeal of the medium lies in the "magic mirror" effect of light striking the polished silver plate and revealing a silvery image which can seem ghostly and ethereal even while being perfectly sharp, and in the dedication and handcrafting required to make a daguerreotype. </p> </section><div class="mw-heading mw-heading2 section-heading" onclick="mfTempOpenSection(13)"><span

There is apparently no other documentary basis which might support statements found in many sources that it is the "first" or "first successful" or "first completely processed" daguerreotype, or that it was presented to de Cailleux at the Louvre in 1837 rather than at an unknown location and date after the 1839 unveiling of the process. According to the <a rel="nofollow" class="external text" href="https://books.google.com/books?id=_iBFAAAAYAAJ&amp;pg=PA173">1884 catalogue of one French museum</a>, a framed set of three plates presented by Daguerre to <a href="/wiki/Fran%C3%A7ois_Arago" title="François Arago">François Arago</a> bore an identically worded dedication. They were among the plates put on display to a French government body in July 1839 when it was deciding on the award of a pension to Daguerre in exchange for the still-secret details of his process.</span> </li> <li id="cite_note-52"><span class="mw-cite-backlink"><b><a href="#cite_ref-52">^</a></b></span> <span class="reference-text">Though it shows the busy <a href="/wiki/Boulevard_du_Temple" title="Boulevard du Temple">Boulevard du Temple</a>, the long exposure time (about ten or twelve minutes) meant that moving traffic cannot be seen; however, the bootblack and his customer at lower left remained still long enough to be distinctly visible. The building signage at the upper left shows that the image is laterally (left-right) reversed, as were most daguerreotypes. Daguerre presented this daguerreotype together with two others: a still-life and a view from the same window labelled <i>midi</i> (noon) to King Ludwig I of Bavaria (<i>The Munich Triptych</i>) in order to publicise his invention. All three daguerreotypes were destroyed by cleaning in 1974 but they are preserved in reproduction.<sup id="cite_ref-51" class="reference"><a href="#cite_note-51"><span class="cite-bracket">[</span>49<span class="cite-bracket">]</span></a></sup></span> </li> <li id="cite_note-53"><span class="mw-cite-backlink"><b><a href="#cite_ref-53">^</a></b></span> <span class="reference-text">Talbot's early "sensitive paper" or "photogenic drawing" process, which required very long camera exposures, should not be confused with the much more practical <a href="/wiki/Calotype" title="Calotype">Calotype</a> or Talbotype process, invented in 1840 and introduced in 1841.</span> </li> <li id="cite_note-91"><span class="mw-cite-backlink"><b><a href="#cite_ref-91">^</a></b></span> <span class="reference-text">Parisian optician Charles Chevalier had long been making assorted high-quality lenses for microscopes, telescopes and other optical devices.
