Nègre initially reproduced the image by François-Auguste Renard, dating from around 1852, using Niépce de Saint-Victor’s process in his first year of experimentation, 1854. In the spring of 1857, however, Nègre submitted a new impression, complete with the addition of delineated clouds etched by aquatint on the plate, as part of “une série de nouvelles épreuves obtenues par son procédé de gravure héliographique” for review by members of the SFP. Nègre appears not to have made a new plate of the same image by his patented process, but rather submitted an impression from the older photogravure plate, which was modified with the aquatint skies in January 1855, according to his notebooks. The fact that Nègre chose to deliver an impression from his experimental phase in photogravure to the Duc de Luynes competition jury suggests the importance that the image had for him. 
This print is included in the portfolio, Charles Négre Treize Héliogravures, 1854-1857 commissioned by André Jammes in 1982 and printed from Négre’s original steel plates. Introducing the project, Jammes writes… Charles Nègre (1820-1880) was one of the most influential photographers of the 19th century. Painter turned genre and architectural photographer, as early as 1855 he brought the hand-pulled photogravure process to an extraordinary degree of perfection. His work in photogravure is classical in the history of photography. The present portfolio demonstrated his successive trials, from the modest “Maçon accroupi” published in La Lumière in 1854, to the large-scale plates of Chartes cathedral, which may be considered his masterpieces. It also includes three Nadar portraits. Produced in 1982 by the renowned connoisseur of 19th century photography and owner of Negre’s original plates, André Jammes, this portfolio is held in the permanent collection of the Metropolitan Museum of Art as well as the National Gallery of Canada. At Saint-Prex, in Switzerland, there is an exceptional experimental atelier where numerous innovative techniques are being essayed, including the revival of photographic etching. It was therefore only natural to have the old steel plates of Charles Nègre printed in the mot favorable condition at this atelier. These thirteen plates are printed from the original steel plates made 125 years ago. The printing methods are absolutely similar to those employed in the XIXth century… A special ink adapted to each plate has to be devised, a very powerful and precise press used, and a hand-made paper produced, covered with “chine collé” according to the methods so appreciated by the Romantics. … This portfolio is a resurrection undertaken in a spirit of scrupulous honesty, presenting images faithful to the old proofs, which now are almost impossible to locate at any price.
The portfolio is held by the Musée d’Orsay, the National Gallery of Canada, the National Gallery of Art (Washington, D.C.), the Metropolitan Museum of Art, and the J. Paul Getty Museum, among others. Unusually for modern iterations of extant vintage prints, it is held not as rare reference material in these institutions’ special-collections libraries, but as part of their photography collections.
The 2 plates of Chartres are some of the largest photogravures made in the 19th century and represent the zenith of Nègre’s achievement.
The thirteen plates are presented in a box with three compartments (86 x 67 cm.), containing the two large-size plates, the 11 smaller ones, and descriptive and historical notes. The edition is limited to 110 copies, 100 of which are for sale. An original etching by Charles Nègre, engraved from the famous self-portrait drawing of Ingres, is included in the text.
