HP5
o
ISO 400/27 BLACK AND WHITE PROFESSIONAL FILM
FOR HIGH PRINT QUALITY AND FLEXIBILITY IN USE
ILFORD HP5 Plus is a fast black and white film. It
is ideal for action, available light and general
purpose photography. HP5 Plus is compatible with
all major processing systems, including those
which give the standard short fixing and washing
times.
EXPOSURE RATING
o
HP5 Plus has a speed rating of ISO 400/27
(400ASA, 27DIN, EI 400/27) to daylight. The
ISO speed rating was measured using ILFORD
o
o
ID-11 developer at 20 C/68 F with intermittent
agitation in a spiral tank.
Although rated at ISO 400/27o, HP5 Plus 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.
Best results are obtained at EI 400/27, but good
image quality will also be obtained at meter
settings from EI 400/27 to EI 3200/36.
HP5 Plus 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 17 and
30.5 metres (55 and 100ft). HP5 Plus 35mm film
is supplied in DX coded cassettes, suitable for all
35mm cameras.
It should be noted that the exposure index (EI)
range recommended for HP5 Plus is based on a
practical evaluation of film speed and is not based
on foot speed, as is the ISO standard.
SPECTRAL SENSITIVITY
Wedge spectrogram to tungsten light
(2850K)
HP5 Plus 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.
Sensitivity
HP5 Plus 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 and 220 lengths and is edge numbered 1 to
19 (120) and 1 to 40 (220).
Wavelength nm
FILTER FACTORS
HP5 Plus 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 11/2 stops.

HP5 Plus
MAKING LONG EXPOSURES
For exposures between 1/2 and 1/10 000 second, no
adjustments are needed for reciprocity law failure.
When exposures longer than 1/2 second are given,
HP5 Plus, 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.

DEVELOPMENT TIMES
The table gives development times for both manual
and machine processing HP5 Plus. 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 to 15%. A pre-rinse is
not recommended as it can lead to uneven
processing.

DEVELOPMENT TIMES
If HP5 Plus has been inadvertently exposed at
settings below EI 400/27, the following guide will
ensure usable negatives are obtained. Obviously,
the quality of negatives processed in this way will
not be so high as conventionally processed ones.
PROCESSING AT DIFFERENT
TEMPERATURES
HP5 Plus film can be processed over a range of
temperatures. Development times at temperatures
o
other than 20°C/68 F may be calculated from the
chart below.
Manual processing (min/20°C/68oF) –
accidental exposure only
For example, if 4 minutes at 20°C/68 F is
o
recommended, the time at 23°C/73 F will be 3
o
minutes and the time at 16°C/61 F will be 6
minutes.

Note Development times may need adjusting to

practices. If an established system is producing
good results, adjust the recommended
development times until the desired contrast level is
obtained. Development times in other
manufacturers’ developers are included for your
convenience, and are only a general guide. Other
manufacturers can and do change their product
specifications from time to time, and the
development times may change as a result.

PROCESSING
HP5 Plus 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. HP5
Plus is very robust in processing and will tolerate
less than ideal processing conditions. Also, it will
not contaminate the processing chemicals.
Safelight recommendations
Handle HP5 Plus 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. Continuous agitation
is recommended in dishes/trays (by rocking the
dish or by interleaving the sheets). As a general
rule, follow the recommendations given by the
processing equipment manufacturer.
A final rinse in water to which a few drops of
ILFORD ILFOTOL wetting agent have been added
will aid rapid and uniform drying.
Drying
To avoid drying marks, use a clean squeegee or
chamois cloth to wipe HP5 Plus film before
hanging it to dry. Dry HP5 Plus at 30–40°C/86o
104 F in a drying cabinet or at room temperature
in a clean dust-free area.
STORAGE
o
Store HP5 Plus in a cool (10–20°C/50-68 F), dry
place in its original packaging.
Exposed film
Once exposed, process HP5 Plus as soon as
practical. Images on exposed but unprocessed film
will not degrade for up to several months when
stored as recommended.
Negatives
Store processed negatives in a cool (10–20°C/50o
68 F), dry place, in the dark. Suitable storage
sleeves include those made of cellulose triacetate,
Mylar or paper (pH6.5–7.5) or inert polyester.
Fixation
After development, rinse the film in water or an
acid stop bath (ILFORD ILFOSTOP or ILFOSTOP
PRO) and fix in ILFORD HYPAM or ILFORD
UNIVERSAL RAPID fixer (1+4) for 2–4 minutes at
o
20°C/68 F. A hardener is recommended only
when processing at high temperatures (above
o
30°C/86 F) or in a roller transport processor.
Washing
Where a non-hardening fixer, such as HYPAM or
UNIVERSAL RAPID fixer, has been used, wash the
film in running water for 5–10 minutes at a
o
temperature within 5°C/9 F of the processing
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.
1 Process the film in a spiral tank.
2 Fix it using HYPAM or UNIVERSAL RAPID fixer.
3 After fixation, fill the tank with water at the same
temperature as the processing solutions, and invert
it five times.
4 Drain the water away and refill. Invert the tank
ten times.
5 Drain and refill it for the third time and invert the
tank twenty times. Drain the water away.
