History of Photography
Back to the history of photography main page.
A daguerreotype is an early type of photograph, developed by Jacques Daguerre and Joseph Nicéphore Niépce, in the 1830s. In daguerreotype photography the image is exposed directly onto a mirror-polished surface of silver bearing a coating of silver halide particles deposited by iodine, bromine and chlorine vapours. The daguerreotype is a negative image, but the mirrored surface of the metal plate reflects the image and makes it appear positive when the silvered surface has a dark ground reflected into it. Thus, daguerreotype is a direct photographic process without the capacity for duplication.
The daguerreotype was the first publicly announced photographic process and while there were competing processes at the time, the accepted scientific etiquette of the time was that discovery was attributed to first published.
