Limited run. Once they're gone, they're gone!


These plates are coated with experimental Orthochromatic emulsion. High contrast when developed in normal developers. For lower contrast, use low contrast developer.


This particular emulsion has a base fog of 0.4, and a Dmax of 3.5. It should make a great negative for albumen prints and other POP processes!


Meter at ASA 25 as a starting point for moderate contrast scenes. High contrast scenes can probably be shot at 32 or even 50 but you'll have to experiment. Lots of room to explore the potential of this emulsion!


Actual plate dimensions:


9x12: 88 x 119

9x12 plates are cut to fit antique metal holders available on the second-hand market.


Gelatin dry plate photography dates from the 1870s when silver halide photographic emulsion was hand-poured onto glass plates and allowed to dry prior to use as a negative. The development of dry plate negatives made photography more convenient than the wet plate process of the Civil War era, which required the negative to be exposed and developed onsite. With dry plate photography, the need for a portable darkroom was eliminated, making photography more accessible and allowing more people to become amateur photographers. When Kodak started producing “modern” film by coating flexible celluloid in the late 1800s, the use of glass as a substrate was rendered obsolete. Dry plate photography faded out of common use by the late 1920s.
