TECHNICAL INFORMATION
DELTA 100
PROFESSIONAL
ISO 100/21º, FINE GRAIN, BLACK AND WHITE
PROFESSIONAL FILM FOR SUPERB PRINT QUALITY
ILFORD Delta 100 Professional is a medium speed, fine grain, black and white film, ideal for pictorial and
fine art photography.
Delta 100 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 100 Professional 35mm film is supplied in
DX coded cassettes, suitable for all 35mm cameras.
Delta 100 Professional rollfilm 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.
Delta 100 Professional sheet film is coated on 0.180mm/7-mil polyester base
with an anti-halation backing which clears during development. It is available in
a wide range of standard sizes. The emulsion faces the user when sheet film is
held in the position shown opposite.
EXPOSURE RATING
Delta 100 Professional has a speed rating of ISO 100/21º to daylight. Best results are obtained at EI 100/21,
but good image quality will also be obtained at meter settings from EI 50/18 to EI 200/24.
It should be noted that the exposure index (EI) rang ofessional is based on a e recommended for Delta 100 Pr
practical evaluation of film speed and is not based on foot speed, as is the ISO standard.

FILTER FACTORS
Delta 100 Professional film may 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.
The exposure increase in daylight may vary with the angle of the sun and the time of day. In the late afternoon
or the winter months, when daylight contains more red light, green and blue filters may need slightly more
exposure than usual.
Cameras with through-the-lens metering will usually adjust the exposure automatically when using filters. With
some automatic exposure cameras, the correction given for deep red and orange filters can produce negatives
under exposed by as much as 1½ stops.
MAKING LONG EXPOSURES
For exposures between 1 and 1/10 000 second, no
adjustments are needed for reciprocity law failure.
When exposures longer than 1 second are given, Delta 100
Professional, along with other films, needs to be given more
exposure than indicated by a meter. Use the graph to
calculate the increased exposure time which should be given
once the measured time is known.
The graph is based on the formulae Ta = Tm 1.26
Ta = Adjusted Time
Tm = Measured Time

DEVELOPMENT TIMES
The table below gives development times for both manual and machine processing Delta 100 Professional. These
times will produce negatives of average contrast suitable for printing in all enlargers The development times are
intended as a guide and may be altered if a different result is needed.
For manual processing in spiral tanks and deep tanks, the development times are based on 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%. For use in rotary processors without a pre-rinse, reduce the spiral tank development
times by up to15%. A pre-rinse is not recommended as it can lead to uneven processing.
