Roger Fenton's photographic processes
Fenton printed from glass plate negatives
The wet collodion process
The wet collodion process used a prepared piece of glass which, in the darkroom, would be coated with collodion and then made light-sensitive with further chemicals. Before the plate could dry, it would be placed in the camera and exposed. Then the plate would be returned to the darkroom and developed, rinsed, fixed, washed, dried and varnished. It was then ready for printing.
