ISO 400/27Âş SHARP, FINE GRAIN, BLACK AND WHITE PROFESSIONAL FILM
EXCELLENT PRINT QUALITY AND C41 PROCESSING CONVENIENCE
XP2 SUPER is a sharp, fast, fine grain black and white film. It can be used for any photographic subject, but
ensures excellent results when there is a wide subject brightness range.
XP2 SUPER is easy to expose, has and extremely wide exposure latitude and gives exceptionally sharp, crisp
prints. The excellent highlight and shadows of XP2 SUPER give enhanced negative contrast for optimum black
and white print quality.
XP2 SUPER is easy to process. It is a black and white film which is processed in C41 type processing
chemicals alongside colour negative films.
XP2 SUPER is very easy to print. Negatives are printed on black and white paper in the same way as
conventional black and white negatives.
WHY XP2 SUPER IS DIFFERENT
XP2 SUPER is a chromogenic film. This means that the dyes which make up the image are formed during
development rather than being present in the film or added later.
The extremely wide exposure latitude of XP2 SUPER is the result of the unique relationship between exposure
and grain in chromogenic films.
The best balance of sharpness and grain is obtained when XP2 SUPER is exposed at EI 400/27.
However, down-rated or overexposed XP2 SUPER negatives have finer grain, the opposite of that
expected and obtained with conventional films. Up-rated or underexposed XP2 SUPER negatives have
only a slight loss in quality. Furthermore, standard C41 processing is recommended for the whole of the
exposure range.
XP2 SUPER 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). XP2 SUPER 35mm film is supplied in DX coded cassettes,
suitable for all 35mm cameras.
XP2 SUPER 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
XP2 SUPER film has a speed rating of ISO 400/27° (400ASA, 27DIN, EI 400/27) to daylight. The ISO speed
rating was measured using standard C41 processing. Although rated at ISO 400/27°, XP2 SUPER can be
exposed over the range EI 50/18–800/30. When higher speed is needed, XP2 SUPER can be rated at up to EI
800/30. For finer grain, when speed is less important, rate the film at EI 200/24, although for finest grain it
can be rated as low as EI 50/18 if required.
The practical implications of this wide exposure range are very important. XP2 SUPER can be exposed at a
setting to suit the job. The benefit of variable speed also provides security against inadvertent over- or
underexposure.
It should be noted that the exposure index (EI) recommended for XP2 SUPER is based on a practical
evaluation of film speed and is not based on foot speed, as is the ISO standard.

FILTER FACTORS
XP2 SUPER film may be used with all types of filters (e.g. 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, XP2
SUPER, 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 metered time is known.
The graph is based on the formulae Ta = Tm 1.31
Ta = Adjusted Time
Tm = Metered Time

CHARACTERISTIC CURVE

curve is representative of 35mm film and roll film
PROCESSING
XP2 SUPER film is processed in the standard C41 colour negative film process. XP2 SUPER film can be
processed alongside all makes of colour negative film. For selecting which negatives to enlarge on black and
white paper, the processing lab can supply proof prints on colour paper.
Safelight recommendations
Handle XP2 SUPER film in total darkness.
C41 type processing
XP2 SUPER film is fully compatible with C41 type processing chemicals, both replenished (e.g. in dip and dunk
or roller transport processors) and unreplenished (e.g. in spiral tanks or with Jobo one-shot rotary processing).
The film can be put through standard C41 lines with no adjustment to processing speed, temperature or
replenishment rates – see “Replenishment rates”.
A benefit of using a professional C41 type processing service for XP2 SUPER film is that the high level of
quality control needed with the professional C41 process should always ensure well processed negatives.
XP2 SUPER film will not affect the quality of the colour material processed or the equilibrium of the processing
chemicals. Any proportion of XP2 SUPER film to colour negative film can be used in a C41 processing line,
while retaining a stable system. Reusable C41 type chemicals, which have been used to process XP2 SUPER
film, can be used to process colour negative film, with no loss of quality in subsequent films.
Replenishment rates
Set replenishment rates for XP2 SUPER film as if it is an ISO 200/24° colour negative film, regardless of how
it was exposed.
Push processing
Push processing is not recommended as, unlike conventional ISO 400/27° films, no practical increase in
film speed is achieved when XP2 SUPER film is push processed. But XP2 SUPER film can be exposed at EI
800/30 and given standard processing.
Conventional processing
We do not recommend conventional black and white processing for use with XP2 SUPER film since
advantages such as grain free images and scanning with ICE will be lost. However, users have
reported that a good quality image may be obtained using conventional black and white chemistry.
Drying
To avoid drying marks, use a clean squeegee or chamois cloth to wipe XP2 SUPER film before hanging it to dry.
Dry XP2 SUPER at 30–40°C/86-104°F in a drying cabinet or at room temperature in a clean dust-free area.
