When was the daguerreotype developed?
Daguerreotype
Invented by Louis-Jacques-Mandé Daguerre and introduced worldwide in 1839,[4][5][6] daguerreotype was almost completely superseded by 1860 with new, less expensive processes yielding more readily viewable images. In the late 20th century, there was a revival of daguerreotypy by a small number of photographers interested in making artistic use of early photographic processes.
Daguerreotype
The daguerreotypes of the 1852 Omaha Indian (Native American) delegation in the Smithsonian include a daguerrotype copied in the camera, recognizable by the contrast being high and a black line down the side of the plate.[116]
