How many of you Photobloggers know what a daguerrotype is? Apparently, it's having a birthday. While the process involved a several second exposure and use of nasty chemicals like mercury, it was the first practical photography. How far we have come.
On the occasion of the 170th anniversary of photography, a daguerrotype showing a family taken in 1842 by Hungarian photographer Jakab Marastoni is displayed in the Hungarian National Museum in Budapest, Hungary. French inventor Louis Daguerre introduced his invention to the French Academy on January 7, 1839.
