It should be noted that the exposure index (EI)

range recommended for PAN F Plus is based on a

practical evaluation of film speed and is not based

on foot speed, as is the ISO standard.

BLACK AND WHITE PROFESSIONAL FILM

FOR HIGH PRINT QUALITY AND FLEXIBILITY IN USE

ILFORD PAN F Plus is an extremely fine grain black

and white film. It has outstanding resolution,

sharpness and edge contrast. These characteristics

make it the natural choice where fine detail and

lack of grain are more important than film speed.

Mural size enlargements from PAN F Plus

negatives show an outstanding range of tone and

detail when the film is carefully exposed and

processed.

SPECTRAL SENSITIVITY

Wedge spectrogram to tungsten light

(2850K)

PAN F Plus is compatible with all major processing

systems, including those which give the standard

short fixing and washing times.

PAN F Plus 35mm film is coated on 0

125mm/5-mil

acetate base and is available in 36 exposure

cassettes, or in bulk lengths of 17 and 30

5 metres

(55 and 100ft). PAN F Plus 35mm film is supplied

in DX coded cassettes, suitable for all 35mm

cameras.

PAN F 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 lengths and is edge numbered 1 to 19.

EXPOSURE RATING

PAN F Plus has a speed rating of ISO 50/18

(50ASA, 18DIN, EI 50/18) to daylight. The ISO

speed rating was measured using ILFORD ID-11

developer at 20

C/68

F with intermittent agitation

in a spiral tank.

Best results are obtained at EI 50/18, but good

image quality will also be obtained when PAN F

Plus is exposed at EI 25/15.

FILTER FACTORS

PAN F 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 1

stops.

TECHNICAL INFORMATION ISO 50/18 BLACK AND WHITE PROFESSIONAL FILM FOR HIGH PRINT QUALITY AND FLEXIBILITY IN USE o PAN F Plus is compatible with all major processing systems, including those which give the standard short fixing and washing times. PAN F Plus 35mm film is coated on 0.125mm/5-mil acetate base and is available in 36 exposure cassettes, or in bulk lengths of 17 and 30.5 metres (55 and 100ft).

PAN F 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, PAN F 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.
PAGE 3
PAN F Plus DEVELOPMENT TIMES The table gives development times for both manual and machine processing PAN F 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.
PAGE 4
PAN F Plus DEVELOPMENT TIMES If PAN F Plus has been inadvertently exposed at settings below EI 25/15 or above EI 64/19, 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.
PAGE 5
PAN F Plus PROCESSING PAN F 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. PAN F 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 PAN F Plus film in total darkness.

PAN F Plus FIX HARDENER ILFORD RAPID FIXER and ILFORD ILFOFIX II must not be used with fix hardeners as they are not compatible with them. If a fix hardener is required then only ILFORD HYPAM fixer can be used. Add ILFORD HYPAM HARDENER to turn HYPAM into a hardening fixer. Generally for most applications modern camera films are sufficiently hardened at manufacture.
