Traditional cubic-grain emulsion with high resolving power and a wide range of halftones (Foma datasheet: RMS 13.5, 110 lines/mm). Rated ISO 100/21 but the maker says it gives good results one stop over (EI 50) or two stops under (EI 400) with no change in development.
Also sold as: Lomography Earl Grey 100, Arista EDU Ultra 100, Kosmo Foto Mono 100, Flic Film UltraPan 100
Lomography Potsdam Kino 100 is often said to be Fomapan 100, but other sources point to ORWO Wolfen UN 54. The base stock is disputed, so it is not listed as a rebrand here.
