TECHNICAL INFORMATION
A MEDIUM SPEED BLACK AND WHITE CAMERA FILM
KENTMERE PAN 100 is a medium speed black and white camera film which is suitable for a variety of
indoor and outdoor photography applications, where good lighting exists.
It has the capability to generate high quality images with fine grain and good sharpness and is a good choice
of film if enlargement prints are desired.
KENTMERE PAN 100 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). KENTMERE PAN 100 35mm film is supplied in DX
coded cassettes, suitable for all 35mm cameras.
EXPOSURE RATING
KENTMERE PAN 100 has a speed rating of ISO 100/21º to daylight. The ISO speed rating was measured
using ILFORD ID-11 developer at 20ºC/68ºF with intermittent agitation in a spiral tank.
FILTER FACTORS
KENTMERE PAN 100 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,
KENTMERE PAN 100, 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
1.26
Ta = Adjusted Time
Tm = Metered Time
