Skull and partial skeleton of a small bird placed directly onto wet silver and collodion emulsion in the wet plate collodion process. The wet plate collodion process dates from 1851 credited to Frederick Scott Archer. It requires the photographic base, commonly glass or tin, to be coated, sensitized, exposed and developed before the wet emulsion begins to dry, usually within a span of about 10-15 minutes. By the nature of this hand created process each plate is unique and cannot be exactly duplicated.
