PANF PLUS

- Technical Information


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

½

stops.


MAKING LONG EXPOSURES

For exposures between ½ and 1/10 000 second,

no

adjustments are needed for reciprocity law failure.

When exposures longer than ½ 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.

The graph is based on the formula Ta = Tm

1.33

Ta = Adjusted Time
Tm = Measured Time
