Foma Bohemia Fomapan 100 Classic in Fomadon LQN

EI is the speed the film was rated at when shooting. Evidence says where each time comes from: the manufacturer’s own data, a named test, a compilation or several agreeing reports (community consensus), or one person’s report. Times marked “not yet verified” come from secondary sources and haven’t been checked against a manufacturer datasheet. Where sources give different times, every one is listed and marked “sources differ”.

Calculated from the 20°C (68°F) time using Ilford’s temperature compensation factors, not taken from a datasheet. Most B&W developers behave well between 18–24°C (64–75°F).

Foma Bohemia Fomapan 100 Classic

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.
