Jules Gabriel Janin (1804 - 1874) a French writer and critic, published a series of reviews of the newly announced daguerreian process in L'ARTISTE. Apparently, having attended Arago's official announcement of the process on 19 August, Janin and others were left confused at the complexity of the daguerreian process. Having read Janin's critique in the August 25 issue of L'ARTISTE, Daguerre called upon him to witness a demonstration of the process at his studio; at this point, only a very few had had such an opportunity. Daguerre started with polishing the plate and moved through all the steps to prepare for the exposure. The camera had been readied and focused on a view out of the window. After a six minute exposure, the plate was "developed" under the mercury vapors, fixed and washed. Upon viewing the finished plate, Janin commented, "The view looks as if it had been drawn by the hand of the fairy queen Mab." Janin expressed his regret that Daguerre had not demonstrated his procedure on 19 August, for it would have shown that it was not too complicated, as Arago had made it appear. This review in the 1 September 1839 issue of L'ARTISTE recounts the demonstration. Also see: Gernsheim, Helmut. L.J.M. DAGUERRE: THE HISTORY OF THE DIORAMA AND THE DAGUERREOTYPE, p. 102 - 103.
This is the first published account of a witness to the demonstration of the daguerreian process as performed by Daguerre. Roosens and Salu No. 2806.
