With great contrasts between light and dark sec-
tions, the exposure range of film is no longer suf-
ficient to register all the subject’s differences in
brightness in both the "light” and the "shadows”.
The decision is left to the photographer as to
which sections he wants to emphasise. For
example, a person can then appear as a dark
silhouette (underexposed) in front of a correctly
exposed landscape or correctly exposed in front
of a "bleached” background (overexposed). Taking a measurement for "light” and "shadows”
and using a compromise exposure calculated
from the two normally leads to unsatisfactory
results, because some differences are lost in
both the light and the dark sections.
Deliberately low or deliberately generous expo-
sures often increase the character of a picture
and can therefore be effectively used as a com-
position tool.
