Léon Vidal (1834-1906) was head of the Association of Musée des Photographies Documentaires, which he founded, and a professor of photography at the École des Arts Decoratifs. This manual covers photomechanical processes invented by Vidal, among which is the Photochromie. It further includes the carbon-gelatin phototypie, albumen techniques and color.
Although this publication states it as the Third Edition, in actuality, it is an outgrowth of an earlier treatise on carbon by the author, and is indeed, a unique work. Roosens and Salu No. 1616.
