ISO 400/27º, FINE GRAIN, BLACK AND WHITE PROFESSIONAL FILM

FOR SUPERB PRINT QUALITY

SPECTRAL SENSITIVITY

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

FILTER FACTORS

DELTA 400 Professional film can be used with all

types of filters (eg colour, polarising and neutral

density filters) in the usual way. Follow the

instructions given by the filter manufacturer.

DELTA 400 Professional 35mm film is coated on

125mm/5-mil acetate base and is available in

24 or 36 exposure cassettes, or in bulk lengths of

5 metres (100ft). DELTA 400 Professional

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

DELTA 400 PROFESSIONAL CHOOSING THE BEST ILFORD DEVELOPER FOR THE JOB DELTA 400 Professional will give good results in a wide range of developers when exposed at meter settings up to EI 3200/36. After choosing your developer, refer to the development times table to check the meter setting needed with that developer. MAKING LONG EXPOSURES For exposures between 1/2 and 1/10 000 second, no adjustments are needed for reciprocity law failure.

DELTA 400 PROFESSIONAL DEVELOPMENT TIMES The table gives development times for processing DELTA 400 Professional film. The times in bold will produce negatives of normal contrast ( 0.62). The development times are intended as a guide and may be altered if a different result is needed. intermittent agitation. Where continuous agitation is used for manual processing (as in a dish/tray or with some types of developing tank), reduce these times by up to 15%.
PAGE 4
DELTA 400 PROFESSIONAL Note Development times may need adjusting to suit individual processing systems and working practices. If an established system is producing good results, adjust the recommended development times until the desired contrast level is obtained. Note Development times in other manufacturers’ developers are included for your convenience, and are only a general guide.

DELTA 400 PROFESSIONAL PROCESSING AT DIFFERENT TEMPERATURES DELTA 400 Professional film can be processed over a range of temperatures. Development at 20ºC/68ºF or 24ºC/75ºF is recommended and the times are given in the development times table. If development is not possible at 20ºC/68ºF or 24ºC/75ºF, the following chart can be used. The chart is based at 20ºC/68ºF for a general developer, and can be used to give an estimate of development times at temperatures around 20ºC/68ºF.

DELTA 400 PROFESSIONAL Agitation Intermittent agitation is recommended for use in spiral tanks and deep tanks. With spiral tanks, invert the tank four times during the first 10 seconds, then invert the tank four times again during the first 10 seconds of each further minute. Otherwise, follow the recommendations given by the processing equipment manufacturer.

DELTA 400 PROFESSIONAL WASH When a non-hardening fixer has been used wash the films in running water for 5–10 minutes at a temperature within 5ºC (9ºF) of the process temperature. For spiral tank use, when a non-hardening fixer has been used, the following method of washing is recommended. This method of washing is faster, uses less water yet still gives negatives suitable for long term storage.
