27 EXPOSURE IN MULTIPLE EXPOSURES
27 Exposure in Multiple Exposures
Generally, the first exposure of a series should be of a relatively dark subject so
that the image in the next exposure will show up clearly. For best results, it is
advisable to decrease the exposure for each shot. Depending on the situation, there
are several ways to do this. One way is to change the ISO setting to a higher value
as described earlier. In this method, you must first decide how many exposures you
want to make on the same frame. If a double exposure, make lSoth exposures at
twice the normal ISO rating; if a triple exposure, make all three exposures at three
times the normal ISO rating, and so forth.
Another way to correct exposure is to use the exposure compensation dial. This
method is the same as that of changing the ISO. That is, for a double exposure, set
the dial to ”1/2” for both exposures; for a triple exposure, at the setting between
”1/2” and ”1/4”, and so on. Both methods described above are merely guideiines,
and your technique will b ene fit greatly from practice.
