Daguerreotype

What is a Daguerreotype?
Daguerreotype was the first published photographic process, was invented by Louis J. M. Daguerre in France in 1839. It soon became the most popular medium in the mid 19th century, producing a unique and permanent direct positive image on a copper plate, without the use of a negative. The plate was exposed in the camera for as long as 20 minutes in daylight, which required the sitter to remain very still for long periods of time. The silver surfaces had a mirror-like shine and, being fragile, were often placed into a special viewing case.  Sizes vary but are measured from double whole plate (8 x 13 inches) to sixteenth plate (1 5/8 to 2 1/8 inches) with the sixth plate the most common (2 x 3 inches).
