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”.
Other temperatures
Colour developers run at 38°C (100°F) with a tight tolerance of around ±0.3°C, so there’s no reliable temperature chart. If you can’t hold the temperature, follow your kit’s instructions for its lower-temperature times.
