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 |

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) |

How they work together
- ID-11
- Fine grain, moderate acutance, full film speed, normal contrast. Excellent balance of fine grain, sharpness, and tonal rendition.
- CatLABS CatLABS X Film 320 (120/Sheet)
- Different emulsion from the 35mm version (which is Kodak Double-X). Origin unclear - likely aerographic stock with finer grain.
