EI is the speed the film was rated at when shooting. Times marked “not yet verified” come from secondary sources and haven’t been checked against a manufacturer datasheet.
Other temperatures
| 18°C | 19°C | 20°C | 21°C | 22°C | 23°C | 24°C |
|---|---|---|---|---|---|---|
| 8:45 | 7:50 | 7:00 | 6:18 | 5:36 | 5:02 | 4:33 |
Calculated from the 20°C time using Ilford’s temperature compensation factors, not taken from a datasheet. Most B&W developers behave well between 18°C and 24°C.
Mixing
| Dilution | 300 ml (one 35mm roll) | 500 ml (one 120 roll) |
