PROFESSIONAL FILM FOR SUPERB PRINT QUALITY
ILFORD DELTA 400 Professional is a fast, fine grain, black and white professional film. It is ideal for action
and available light photography and also gives fine grain results for pictorial and fine art photography. DELTA
400 Professional film gives excellent performance in seasoned developers.
Although rated at ISO 400/27º, DELTA 400 Professional film can produce high quality prints when exposed at
meter settings up to EI 3200/36 and given extended development in ILFORD ILFOTEC DD-X, ILFOTEC HC,
MICROPHEN or ILFOTEC RT RAPID developers.
DELTA 400 Professional 35mm film is coated on 0.125mm/5-mil acetate base and is available in 24 or 36
exposure cassettes, or in bulk lengths of 30.5 metres (100ft). DELTA 400 Professional 35mm film is supplied in
DX coded cassettes, suitable for all 35mm cameras.
DELTA 400 Professional roll film is coated on 0.110mm/4-mil clear acetate base with an anti-halation backing
which clears during development. It is available in 120 lengths and is edge numbered 1 to 19.
EXPOSURE RATING
DELTA 400 Professional has a speed rating of ISO 400/27° to daylight. The ISO speed rating was measured
using ILFORD ID-11 developer at 20°C/68°F with intermittent agitation in a spiral tank.
Best results will be obtained at normal contrast, but good image quality will also be obtained at meter settings
from EI 200/24 to EI 3200/36. It should be noted that the exposure index (EI) range recommended for DELTA
400 Professional is based on a practical evaluation of film speed and is not based on foot speed, as is the ISO
standard.
