Talk:Daguerreotype/Archive 2

Was photography (and the daguerreotype) invented in 1835, or in 1839?
At the end of an appreciative review of the Diorama one could read In the Journal des artistes of the 27 September 1835:

"It is said that Daguerre has found a way to collect, on a plate  prepared by him, the image produced by the camera obscura, so that a portrait, a landscape or any view, projected on to this plate by the  ordinary camera obscura leaves an imprint in light and shade, as well as the most perfect of all drawings ...  a contraption placed over this image will preserve it for an indefinite time ... the physical sciences have probably never before presented a miracle  to match this one." (my translation)

In fact, at this time Daguerre had not found a way to fix the image of the daguerreotype or to take portraits, as the exposure times were too long,

Original text:

À la suite d’un commentaire élogieux sur le spectacle du Diorama, La Vallée de Goldau1, on peut lire dans le Journal des artistes du 27 septembre 1835 : « [Daguerre] a trouvé dit-on, le moyen de recueillir, sur une planche préparée par lui, l’image produite par la chambre noire, de manière qu’un portrait, un paysage, une vue quelconque, projetée sur ce plateau par la chambre noire ordinaire, y laisse une empreinte en clair et en ombre, et présente ainsi le plus parfait de tous les dessins… Une préparation mise par dessus cette image, la conserve pendant un temps indéfini… Les sciences physiques n’ont peut-être jamais présenté une merveille comparable à celle-ci2. »

The following quotes are from The Silver Canvas, and some of them are used to establish the date of the first daguerreotype in The Encyclopedia of Ninteenth-Century Photography

When the Paris correspondent of the Athenaeum reported in January 1839 about the invention, he commented that Daguerre's current images were better than those he had seen "four years earlier".

The following year, in September 1836, the father of Eugéne Emmanuel Viollet-le-Duc wrote his son that a friend told him of seeing a work by Daguerre taken from atop the Diorama showing the hills of Montmarte one-half miles away. With only a weak magnifying glass, he wrote, it was possible to distinguish among the windmills on the hill the one serving as the telegraph tower, despite the fact that it measured only about three-quarters of an inch on the plate. It was even possible, he added, to distinguish all its working parts and sails, including the glittering iron wires used to operate arms of the semaphore telegraph. The letter concluded the descriiption by adding that Daguerre's new device contained such minuscule details it could not possibly have been produced by an artist.

Footnote:

This little known description is the most detailed evidence proving that by the early winter 1836 Daguerre already had been able to produce a view that could be examined by others and that was clear enough to show minute details. See Eugène-Emmanuel Viollet-le-Duc, Lettres de Italie: 1836 - 1837 addressée à sa famille (Paris: L. Laget, 1971), 165. RPSM (talk) 11:43, 15 January 2015 (UTC)

Article text now:


 * After experimenting with the process with Dumas for five years, Daguerre began producing daguerreotypes around 1834. He announced his invention to the Journal des artistes on 27 September 1835. A review discussing the process entitled "La Vallée de Goldau" reads:

The review does not discuss the process at all. It is a review of a specific Diorama exhibition (La Vallé de Godau]] It is a picturesque valley in Switzerland, and you need to know something about Daguerre's Diorama to understand the context and the link to Daguerre's Diorama has disappeared.

The paragraph from the 1835 article in Journal des artistes which I translated from the French, has the first known mention of daguerreotypy in print (1835), is completely irrelevant to the review and is tacked onto the end of it - "a veiled reference"

The point of this was that some people confuse the public announcement of daguerreotypy (1839) with its invention. The invention was clouded in secrecy and some clues about how it progressed can be gathered from Daguerre's and Niépce's correspondence. RPSM (talk) 16:10, 11 February 2015 (UTC)


 * Note that the 1835 text in no way justifies saying that Daguerre "announced" his process to the Journal des artistes, or to anyone else except in strict confidence. It is only presented as an intriguing rumor. 66.81.245.248 (talk) 23:40, 15 July 2017 (UTC)
