January 31, 2008 History of Photography -1852: Fredrick Scott Archer invented the wet plate colloidal process. Revolutionary because they were made on glass -paper was made (Albumen paper) out of egg whites. It made the absorption process significantly faster (could absorb emulsion faster). -1854: wet plate process adapted to make an ambrotype. Ambrotype: underexposed so it had no blacks, bleached to make highlights light and the shadows disappeared. Then place against a black enamel piece of metal to make it look like a daguerreotype (cheaper). -Tin Type: popular form of direct positive because cheap and easy to make (during civil war). -David Octavius Hill: Scottish artist, commissioned to paint the faces of all of the clergy who separated from the English church, but there were 400 of them so instead he took a picture of them as a group and then painted from that picture for 23 years after. -Used calleotype (English process) because deugerrotype’s were not suitable for him.
