This file was produced from images generously made available by the Bibliothèque nationale de France (BnF/Gallica) "Nouveau moyen de préparer la couche sensible des plaques destinées à recevoir les images photographiques" by M. Daguerre is a scientific publication written in the mid-19th century. This work documents a technique developed for preparing photographic plates using a novel method that enhances their sensitivity to light, marking an important advancement in the early field of photography. The book provides a detailed methodology for preparing the plates, emphasizing the use of various metals and chemical substances to create a more effective photosensitive layer. Daguerre discusses the importance of manipulating these materials to achieve better tonal reproduction and overall image quality. He outlines a two-part preparation process involving careful cooling and heating of materials, ensuring consistency in the results that can be achieved. Through meticulous experimentation, Daguerre aims to elevate the art of capturing images, demonstrating a deeper understanding of the chemical processes involved in photography during this pioneering era.
