MONCKHOVEN, Photographie sur papier, 1857 Avec échantillons de papier

First edition.
Désiré Van Monckhoven is one of the most famous Belgian photographers. Chemist he participated in the dissemination of knowledge of photographic chemistry then in full explosion.
Photography on paper was invented a few years earlier by Talbo to overcome the drawbacks of daguerreotypes, in the 1850s it was still little used but it was this process (negative-positive) that allowed the photographs to be widely distributed.
In this book Monckhoven gives the precise implementation of this process by giving in particular two samples of paper which allow to touch the papers which were then used in the middle of the XIXth century.

Following Monckoven's text were added 8 handwritten pages on collodion (another photographic process) and two notes on loose paper on these processes.
