This camera for the daguerreotype process was introduced by Peter Wilhelm Friedrich Voigtlander (1812-1878) in 1841. The focusing screen placed at the widest part of the chamber, and there was a magnifying glass on the shorter of the two cones facilitate focusing. Once the picture was clear, the photographer had to go to the dark room and change the focusing screen by a plate daguerreotype.
official replica Voigtländer 1978 its first metal camera to make daguerreotypes , which were manufactured only 600 units between . 1840 and 1841. While the original camera only have three complete copies worldwide, official replicas are also highly valued and scarce < / font>
mark German Voigtländer is precisely the oldest in the photographic industry . He started his career in Vienna in 1756 dedicated to mechanical precision products and optical instruments. It is thus not surprising that when embarked in the field of photography do it as a technological leader and protagonist of important technical advances
In fact, the piece in question is first camera using a photographic lens precision and high speed for the time (down about twenty times the time needed to make a portrait, from 30 minutes to just 2 or 3 minutes per picture) This was. possible. thanks to lenses Jozef Maximilián Petzval , a mathematician and university professor collaboration between Petzval and Peter Voigtländer (grandson of the founder) revolutionized the world of photography with advances such as their use lenses. the contribution of Petzval was so valuable that since 1929 the medal is awarded with his name in gratitude. to the contributions made in the field of scientific photography
Despiece camera Voigtländer Daguerreotype
The camera is fully metallic, is conically shaped and uses a lens with a focal length of 150mm, which are up to 16 times greater as used so far . resulting images are of circular shape , as you can be seen below:
It is noteworthy that, just one after months of famous session 10 August 1839 in which Francois Arago announced the photographic process invented by Daguerre, one German familar firm as Voigtländer got revolutionize the fledgling industry .
