1 janv. 1839 - Daguerreotype

Description:

Introduced in 1839 in France by Louis J. M. Daguerre, the first photographic print process was the daguerreotype. It was made on a silver-coated copper plate which was, for all practical purposes, a mirror. The sensitizing agent was iodine, the developing agent was mercury. Once exposed in a camera and developed, the plate became a photograph on a mirror. Daguerreotypes were rarely used after 1860.
