Rockland Ag-Plus Photographic Emulsion is a premium gelatin-silver emulsion, with higher sensitivity, a convenience if the emulsion is used in a camera instead of film, as is the case with tintypes, ambrotypes and some other alternative processes.
It is also a help when oversize prints are made at a considerable distance from the enlarger. Like Liquid Light, Ag-Plus photographic emulsion is completely free of phenol fumes and safe for use in darkrooms.
