Development time
| Dilution | EI | Time | Temp | Agitation | Timer |
|---|---|---|---|---|---|
| 1+49 | 200−⅔ stop | 10:30 | 20°C / 68°F | Standard | Start timer |
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 |

| 13:08 | 11:46 | 10:30 | 9:27 | 8:24 | 7:34 | 6:50 |
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) |
|---|---|---|
| 1+49 | 6 ml developer + 294 ml water | 10 ml developer + 490 ml water |
How they work together
- HC-110
- Fine grain, high acutance, full film speed, normal contrast. Full-scale with good shadow detail.
- 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.
- Notes on this pairing
- High acutance, low contrast.
