Roger Fenton's photographic processes
Fenton printed from glass plate negatives
Salted paper print
The salted paper print used paper which had been prepared by coating it in a salted solution. After drying, it would be made light-sensitive in the darkroom and then placed in a frame in contact with the glass negative to be exposed to sunlight. Once the image had appeared satisfactorily on the paper, the print would be processed, washed, fixed and toned.
