TECHNICAL INFORMATION
A HIGH SPEED BLACK AND WHITE CAMERA FILM
KENTMERE PAN 400 is a high speed black and white camera film which is suitable for all aspects of
general purpose photography and is capable of generating sharp, fine grain, high quality images. It is
particularly suitable for working with action shoots and available light situations.
KENTMERE PAN 400 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 400 35mm film is supplied in DX
coded cassettes, suitable for all 35mm cameras.
EXPOSURE RATING
KENTMERE PAN 400 has a speed rating of ISO 400/27º 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 400 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 400, 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
1.30
Ta = Adjusted Time
Tm = Metered Time
