Louis Daguerre discovers use of silver iodide in photography
Pioneer of photography, Louis Daguerre (1787 1851) developed the process of the daguerreotype. One of the most significant problems which occurred during the invention of photography was getting the image to remain, to resolve this issue Daguerre concentrated on the properties of silver salts. He discovered a photographic process which involved exposing a thin silver-plated copper sheet to the vapour from iodine crystals which produced a coating of silver iodide on the surface. This plate could then be exposed with the camera to create a photograph. The engraving presents an image of Daguerre experimenting within his workshop with the silver iodide which became a crucial step in the photographic process. Date: 1830s

EDITORS COMMENTS
In this evocative image from the 1830s, we find the pioneering figure of Louis Daguerre (1787-1851) deeply engrossed in his experimental work within the confines of his workshop. Known as the father of photography, Daguerre is celebrated for his groundbreaking invention of the daguerreotype process. During the inception of photography, one of the most formidable challenges was maintaining the longevity of the captured image. To address this issue, Daguerre focused his attention on the chemical properties of silver salts. The enlightening scene portrays Daguerre in the act of investigating the use of silver iodide, a crucial component in the photographic process. By exposing a thin silver-plated copper sheet to the vapors of iodine crystals, he was able to produce a layer of silver iodide on the surface. This treated plate was then susceptible to exposure with a camera, resulting in the creation of a photograph. The captivating image encapsulates the spirit of scientific discovery and innovation that characterized the 19th century. Daguerre's relentless pursuit of knowledge and his unwavering commitment to overcoming the obstacles in the development of photography led to the creation of an enduring art form. The engraving stands as a testament to the transformative power of human curiosity and the indelible impact of scientific discoveries on the world.
