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).

How they work together

T-Max Developer
High acutance, full film speed, normal contrast. Enhanced shadow detail in normally processed and push-processed film.
Foma Bohemia Fomapan 200 Creative
Modern cubic-and-T-crystal emulsion with high resolving power (Foma datasheet: RMS 14.0, close to Fomapan 100). Rated ISO 200/24; the maker says it gives good results from EI 100 (one stop over) to EI 800 (two stops under) with no change in development.
Notes on this pairing
  • Kodak T-Max Developer 1+4. Guide gives 5 to 6 min; lower figure used (lower value gives lower contrast). Spiral tank: continuous for the first 30 s, then 10 s each minute.
