Blanquart-Évrard, [Louis Désiré]. LES COULEURS EN PHOTOGRAPHIE: CAUSERIE. Offprint from: Memoires de la Société des Sciences, de L'Agriculture et des Arts de Lille. 3rd series, volume 9. [Lille: L. Danel, 1871]. First edition. 8vo., 12 pp., with 4 photographic plates. Bound in contemporary yellow paper wrappers with the author and title in manuscript on the front cover. Wrappers are dusty with a short closed tear and lacking the lower front tip. The text is unopened, with the plates in very good condition.

This pamphlet is an offprint from the above mentioned journal, the final contribution from Blanquart-Évrard, the president of the society. The text is a brief discussion of the theory and development of color photography, achieved by using three layers of emulsion, each absorbing one of the three primary colors, with each containing a dye that passed its color complement. This was the basis of every modern color process, and is commonly called the "subtractive" process. Both Louis Ducos du Hauron and Charles Cros announced their similar process on May 7, 1869 at a meeting of the Société Française de Photographie, neither aware of the other's experiments.

Included, following the text are three photographic plates from color separation negatives of flower leaves provided by Louis Ducos du Hauron: red, blue and yellow, and printed on thin sheets of bichromated gelatin, incorporating carbon pigments. The fourth, and final plate is printed combining the three individual separations to make a full color photograph.

In Eder, p.646, he states," Blanquart-Évrard, of Lille, wanted to exploit Du Hauron's process and establish, in 1870, a three-color printing establishment. Du Hauron had already furnished a set of three-color negatives for this purpose, but alas, the Franco-German war forced the postponement of the project until 1871. Unfortunately, Blanquart-Évrard died in April, 1872, but he had reported the process to the Society of Sciences at Lille." Although Cros and Ducos du Hauron exhibited examples of their three-color photographs as early as 1869, in neither of their publications prior to Blanquart-Evrard's, is there an example.

This is the first publication to include an original color photograph from life, with WorldCat locating copies only at the George Eastman House, Getty Research Institute, Bibliotheque National de France, and BM Lyon, none of which are identified as an offprint. Roosen and Salu 928.

Cros, Charles. SOLUTION GÉNÉRALE DU PROBLÈM DE LA PHOTOGRAPHIE DES COULEURS. Paris: Gauthiers-Villars et au Bureau du Journal Les Mondes, 1869. First edition. 8vo., 12 pp., printed wrappers. There is a short separation of the wrappers at the spine. A near fine copy. Housed in a pamphlet folder of paper over boards with printed labels.

Charles Cros (1842 - 1888) and Louis Ducos du Hauron, simultaneously but independently discovered and published the basic principles of photographic color by the subtractive method. In 1869, Cros published an article in Les Mondes in which he describes a letter he had deposited in 1867 with the Académie des Sciences that outlined his color process. The contents of his letter was made public on May 7, 1869 at a meeting of the Société Française de Photographie when a similar process by Louis Ducos du Hauron was also announced. Cros continued to explore photography in color and in 1877, he was supported in his experiments by the Duke of Chaulnes. Very few examples of his color photographs survive. This pamphlet is a cornerstone work on the development of color photography.

Ducos du Hauron, Louis. LES COULEURS EN PHOTOGRAPHIE ET EN PARTICULAR L'HÉLIOCHROMIE AU CHARBON. Traité contenant, dans leur état le plus récent, les formules et la mise en pratique du système de photographie des couleurs publié par l'auteur au mois de mars 1869. Paris: A. Marion, Janvier 1870. First edition. 8vo., 82, (1) pp. Printed wrappers. Moderate chipping to the paper spine. Near fine. Housed in a cloth pamphlet case with a calf label in gilt, inset into the front cover.

Louis Ducos du Hauron and Charles Cros, simultaneously, but independently, discovered the basic principles of photographic color by the subtractive method. Ducos du Hauron published his process in 1869, and further elaborated upon it as applied to tricolor carbon printing in this publication of 1870; additionally, he refutes Cros' claim to priority.

Lamy, successeur, 1876. First edition. 8vo., 12 pp. Printed paper wrappers, which are partially separated at the spine; with a small stain on the rear wrapper. Very good.

This is the controversial letter sent by Louis Ducos du Hauron to the Société Française de Photographie establishing his claim to historical priorities in early color systems.
