message: I've got to say this article is pretty flimsy, considering the amount of information out there on LJM Daguerre. A good place to start is with any book by Helmut and Alison Gersheim- they've written extensively on him. 
There should probably be more of a focus on Daguerre's full career, as he was accomplished in a number of media, most notably painting. The diorama and panorama were certainly both a big deal in their time. I think they warrant more of a mention. 
The description of Daguerre's relationship with Niepce is also a bit flimsy. It could be said that Daguerre took advantage of Niepce and his family. There is also no mention of the fact that the discovery of the action of mercury vapor on the exposed photographic plates was an accident, or that Daguerre perfected his process in 1837 and only sold it to the French government when he could not find a way to sell the process privately. It may also be notable that perhaps more than he was an artist, Daguerre was an excellent businessman.

thread_title:  Quality Issue 

message: The site http://www.sepiatown.com/100471-Boulevard-du-Temple-by-Louis-Daguerre-Paris-France has the results of research by Nicholas Jenkins of Stanford University. However, the image used by him is the mirror image of the one usually seen and indeed the one seen here. From his viewing of his image, Nicholas Jenkins's research has led him to conclude that the picture was taken in a southerly direction from the northern side of the Place de La Republique. It shows the then start of Boulevard du Temple (since covered by the extension to La Place de la Republique.) This seems unlikely as, in Google Maps, Daguerre's image aligns well with the view to the north (i.e. towards La Place de la Republique)taken from the junction of Boulevard du Temple and Rue des Fille de Calvaire. Particularly, in Google Maps, note the building to the northwest. In the original, there is writing (an advert of some sort) on the south-facing wall. In Google Maps, ironically, there is a graffito, but the same outline of the south wall can be seen and the building has the same number of floors.  — Preceding unsigned comment added by 81.104.46.239 (talk) 11:05, 18 November 2011 (UTC)

message: The following sentence is rather ambiguous:
"To protect his own invention, Daguerre himself registered the patent for Britain on 12 August 1839 (a week before France declared it "Free to the World"), and this greatly slowed the development of photography in that nation."  It is not absolutely clear whether the development of photography was slowed in Britain or France.
Suggested improvement:
"To protect his invention, on 12 August 1839 (a week before France declared it "Free to the World") Daguerre registered the patent for Britain, and this greatly slowed the development of photography there."

message: It has recently been discovered that Daguerre may have misled Niépce's son about the value of the invention in order to better claim any profits from it individually.[citation needed] 
This is the assertion of the photohistorians Helmut and Alison Gernsheim. I have not read it in their works, but I have seen a reference to it. It is, apparently, without foundation. 
The first part of The Silver Canvas by Bates and Isabella Lowry, devotes itself to tracing the change from Niépce's asphalt (Bitumen of Judea) on pewter plates process heliography to the polished silver sensitized with fumes from iodine crystals and developed in mercury vapour (Daguerreotype). When the second process could be described as a separate, new process, Daguerre drew up a new version of the contract between himself and Nicephore Niépce's son, Isadore. Both versions of the contract (agreement) are reproduced in full in Eder's History of Photography In any case, Daguerre honoured his debt to Isadore by seeing to it that both he and Isadore received government pensions through the good offices of Francois Arago (scientist and politician) so no one was done out of anything.
Niépce was born in Chalon-sur-Saône, Saône-et-Loire, where his father was a wealthy lawyer; this caused the whole family to flee the French Revolution. His older brother Claude (1763–1828) was also his collaborator in research and invention, but died half-mad and broke in England, having squandered the family wealth in pursuit of non-opportunities for the Pyréolophore.

thread_title:  Was Daguerre involved in skullduggery to pull the wool over Isadore Niépce's eyes? 

message: What does it means: "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."?!
An integral film contains a negative and a positive part. So it is posible to make copies without reproduction. 95.165.138.166 (talk) 22:25, 27 September 2015 (UTC)
