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,
FP4 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.
