Synopsis

Photogravure (1895) is a book written by Henry R. Blaney that explores the technique of photogravure, a printing process that allows for the reproduction of photographic images with a high level of detail and tonal range. The book provides a comprehensive overview of the history, theory, and practice of photogravure, including detailed instructions for the preparation of plates and the printing process. It also includes a number of examples of photogravure prints, showcasing the range of artistic possibilities offered by this technique. Overall, Photogravure (1895) is a valuable resource for anyone interested in the history and practice of photography, as well as for artists and printmakers seeking to explore new techniques for image-making.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.

INTRODUCTION.
Arout the year 1820 Niccphore Niepce made the discovery that bitumen, under certain conditions, was sensitive to light. He dissolved it in oil of lavender, and spread a thin layer of the solution thus obtained upon stone. This he exposed under a drawing- {making the paper transparent by waxing), and after sufficient exposure, oil of lavender was poured on. Those portions of the bitumen which had been exposed to the action of the light had become insoluble, and so remained while the lines which had been protected by the drawing were dissolved away. By treating the stone with an acid these lines were bitten or eroded, and could be printed from. Niepce afterward employed metal plates instead of the stone.
Here we have the foundation for a number of printing processes of the present day, including photogravure.
For many years, however, progress in processes for intaglio printing was very slow. In 1852 Talbot introduced a process termed photoglyphy, and in 1854 Paul Pretsch

Présentation de l'éditeur

This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
