MAKING LONG EXPOSURES

For exposures between

2 and

10 000 second, no

adjustments are needed for reciprocity law failure.

When exposures longer than

2 second are given,

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.
