I quote from "Pictorial Landscape Photography" (The Photo Pictorialists of Buffalo, 1921)
"Our own preference is for Orthonon plates [...]. There are now several other brands of the same type of plate -- orthochromatic and double coated, the emulsion being very considerably faster on the surface than in the lower layer."
I know Forte made a double-coated film (think ASA 100) claiming the same characteristics (a slow and fast coating), but alas, Forte is dead, and I don't have much left.
Are there any other sheet films made out there that are 'double-coated' in this manner?
