FILM Ferrania Orto in HC-110

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).

HC-110

Fine grain, high acutance, full film speed, normal contrast. Full-scale with good shadow detail.

FILM Ferrania Orto

Orthochromatic version of the P30 cine-derived emulsion (2023), with high silver content and strong contrast; development close to P30.

Notes on this pairing

• Kodak dilution G. Ferrania gives 30 to 45 min; lower figure used. 5 min pre-wet, agitate the first minute, then stand. For normal to low-contrast scenes. User-feedback guide. Ferrania publishes these as times collected from user feedback, not its own tests.
