CHALLENGING SHOOTING CONDITIONS
EXTRA BRIGHT OR DARK OBJECTS
Exposure meters are calibrated for a medium gray scale value (18%
reflection), which corresponds to a regular, i.e. average image sub-
ject.
Should the object reflect more light, e.g. a snowscape, on the beach,
in front of brightly colored buildings or from a white wedding dress, a
setting in accordance with the shutter speed and aperture suggested
by the light balance would result in underexposure.
Conversely, objects with predominantly dark details (a black locomo-
tive, a captain’s dark blue uniform) would result in overexposure.
There are two basic solutions for this problem:
– Where possible, carry out exposure metering in another image
section, where the object displays average reflection.
– The values delivered by the exposure meter are corrected manually
from experience.
