In History Of Photography Daguerreotypes In 1839 the Academy of Science in Paris, France made an announcement that would change our view on the world and ourselves forever. An artist named Louis Jacques Mand Daguerre and a amateur french scientist had developed a process by which a permanent image could be printed on a silver plated sheet of copper and the process could be duplicated and used commercially. France decided to give this gift to the world and thus the first Daguerreotype was born. Although daguerreotypes in truth were not the first photo ever taken but because of his development of the commercial process Mr. Daguerre is usually credited with developing the worlds first photographs. A fellow countryman named Joseph Niepce made the first actual image of a view from a window in 1826 but Mr.
Niepce died in 1833 before his project could be fully completed. Unlike Niepce's process which used pewter and resin, Daguerre's process used silver plated copper sheets with iodine to make them light sensitive and by exposing them in a camera using warm mercury vapors and setting the image with distilled water created wonderful life like images he called daguerreotypes, (named after the creator). Daguerreotypes where developed in natural light in artist studios. The subject had to hold perfectly still for up to 45 minutes. Children where restrained with harnesses and metal neck braces which can t have been the most comfortable thing for the children to put up with.

To fix the image, the plate was immersed in a solution of sodium thinsulate or salt and then toned with gold chloride.
Hallmark Stamped marks on the daguerreotype plate that identify the plate manufacturer or photographic supply house. Hallmarks usually consist of symbols, initials, and / or numbers.
