Paperback. Condition: New. Print on Demand. This book dives into the complex science behind the development of a latent image on photographic plates. It explores the theories of the photographic process and delves into the functions and properties of chemical substances used as developers. The author traces the history of development, from the early discoveries of the 19th century to the present day, highlighting significant advancements and innovations. The book examines the relationship between the chemical structure of organic compounds and their developing power, providing a framework for understanding the mechanisms involved in the process. It also offers practical guidance on selecting and using different developers, considering factors like solubility, color, and the impact on the gelatin layer. With its comprehensive examination of the theory and practice of photographic development, this book is a valuable resource for photographers seeking to master the art of capturing images through the lens. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

Couverture souple. Condition: Bon. Edition originale. 1 vol. in-4 (26 x 17 cm), (4), 86, (1) pp., broché, couverture muette moderne (papier vergé bleu), bord des feuillets légèrement bruni, quelques minimes déchirures marginales, bon état. Edition originale rare de la thèse d'Alphonse Seyewetz (1869-1940), élève de Jules Raulin, à qui cette thèse est dédiée. Seyewetz devint directeur adjoint de l'Ecole de Chimie Industrielle et directeur aux Usines Lumière. Il est l'auteur de très importants travaux scientifiques concernant la chimie photographique et la chimie organique (matières colorantes). Cette thèse est divisée en trois parties : considérations générales sur les combinaisons des matières colorantes basiques avec les matières colorantes acides ; thermochimie des combinaisons des matières colorantes acides avec la fuchsine ; application de la précipitation des matières colorantes basiques avec les colorants acides à l'analyse qualitative et quantitative des matières colorantes (teignant ou non les fibres de coton, laine, soie). REFERENCES: Lavédrine B & ‎Gandolfo JP : The Lumiere Autochrome: History, Technology, and Preservation, p. 37: "In 1900 Seyewetz defended his thesis on combinations of acid and alkaline dyes at the Faculty of Science, Lyon. Through the collaboration that he established with the Lumière brothers, Seyewetz was able to put his knowledge of synthetic dyes to work in an industrial context. Parallel to his ongoing academic career, Seyewetz participated in research and development projects as head of the chemistry unit at the Lumiere factory. His scientific contributions were considerable over the course of his carrer, coauthoring with the Lumiere over two hundred scientific papers in fields such a photographic development, toning, fixing, bleaching, and intensification."; Meunier M : Nécrologie : Alphonse Seyewetz, Bulletin de l'Association amicale des anciens élèves de l'Ecole de chimie industrielle de Lyon, 1940, N°9, 4-5 : "En 1900, il (Alphonse Seyewetz) soutint très brillamment sa thèse de Doctorat de l'Université de Lyon, avec un Mémoire relatif à la combinaison des colorants acides et basiques ; il publia également, avec son ami, Paul Sisley, un important ouvrage sur la chimie des matières colorantes artificielles, qui leur valut une Médaille d'or à la Société industrielle de Mulhouse, et qui constituait un développement de l'enseignement à l'Institut de Chimie.".…
