Fait partie de Historical Photographic Processes Collection
Series contains wet plate collodion negatives, a process usually credited to William Scott Archer , in wide use between 1851 and 1885. The process uses light-sensitive silver halides in collodion on a glass base and the negatives needed to be exposed while still wet. Positive prints of wet plate negatives were usually made using the albumen silver process. The process was superseded by the more convenient dry plate process.
