Field Camera Lens
notes: label: Description
content: The wet collodion process produced glass negatives that were used to print positive images on albumen paper (coated with a light-sensitive mixture including egg whites) or were placed against a dark background to produce ambrotypes, which appeared positive. Collodion could also be poured onto iron plates, used to produce tintypes-- positive images that required no printing. Itinerant photographers who turned out quick, inexpensive portraits for soldiers and civilians favored tintypes. Other photographers who visited camps and battlefields produced glass negatives, which they sent to studios for printing.
