Datasheet

DELTA 400 Professional film can be processed in
all types of processing equipment including spiral
tanks, rotary processors, dishes/trays, deep tanks
and automatic processors. Standard capacity
figures and replenishment rates can be
maintained. When fixing DELTA 400 Professional
film, however, slightly longer times than used with
conventional film are recommended for best
results.

CHARACTERISTIC CURVE
Relative log exposure
DELTA 400 Professional 35mm film developed in
ILFORD ID-11 stock for 8 minutes at 24°C/75ºF
with intermittent agitation.
PROCESSING
Safelight recommendations
Handle DELTA 400 Professional film in total
darkness. For very brief inspections during
processing, use the ILFORD 908 (very dark green)
safelight filter, with a 15W bulb, fitted in a
darkroom lamp (such as the ILFORD DL10 or
DL20). Do not allow direct lighting from the
safelight to fall on the film.
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.
Stop, fix, wash and rinse
For best results it is recommended that all process
solutions are kept at the same temperature or at
least within 5ºC (9ºF) of the developer
temperature.
Stop Bath
After development the film can be rinsed in water
but we recommend that an acid stop bath is used
such as ILFORD ILFOSTOP (with indicator dye) or
ILFOSTOP PRO (without indicator dye). ILFOSTOP
PRO is recommended for all machine processing
applications. When tanks or dishes (trays) of
process solutions are in use a stop bath
immediately stops development and reduces carry
over of excess developer into the fixer bath. This
helps to maintain the activity and prolong the life
of the fixer solution.

The process time given is the minimum required, if
necessary a longer time may be used and should
not cause any process problems provided it is not
excessive.
Fix
The recommended fixers are ILFORD RAPID FIXER
and ILFORD HYPAM liquid fixers and ILFORD
ILFOFIX II powder fixer,all are non-hardening
fixers.
