1851 Frederick Scott Archer introduces the "Collodion" process. Collodion, is a thick and syrupy liquid, that is made by dissolving nitrated cotton in a mixture of alcohol and ether.This wet plate method proved to be a faster process, reducing exposure times to two or three seconds, but it required a considerable amount of equipment on location. The next year, Archer introduces Ambrotypes based on collodion. Ambrotypes produced high quality and much cheaper image than the Daguerreotypes but the process was very different.
