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.

How they work together

ID-11: Fine grain, moderate acutance, full film speed, normal contrast. Excellent balance of fine grain, sharpness, and tonal rendition.
Ilford Delta 3200: Ultra-high speed film. Popcorn grain structure but captures images in almost darkness. Low native contrast allows for heavy pushing.
Notes on this pairing: EI 3200 (Meter setting 3200).
