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
