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

D-76
Fine grain, moderate acutance, full film speed, normal contrast. Long density scale with excellent shadow detail.

Medium-speed, very fine-grain classic Kodak panchromatic film (1954-2011); discontinuation announced 2010 with final stock in 2011.
Notes on this pairing
  • Small tank, agitation every 30 s. J-78 row is for PLUS-X Pan / PLUS-X Pan Professional (the pre-2007 emulsions).
  • Small tank, agitation every 30 s. J-78 row is for PLUS-X Pan / PLUS-X Pan Professional (the pre-2007 emulsions). Kodak warns tank times under 5 min may give uneven development.
