Front·lit subjects against dark background
If a brightly lit subject is positioned against a dark background,
and is not in the center, centerweighted metering places too
much emphasis on the dark center of the picture. The result is
a correctly exposed background, but an overexposed main
subject. However, with automatic mUlti-pattern metering, the
camera automatically integrates both the dark background and
bright subject to ensure the best overall exposure.
Scenes with high reflectivity
If a scene contains spectral highlights, such as the sun itself or
bright reflections from water or metallic objects, the main sub-
ject will come out as a silhouette with regular centerweighted
metering. However, with automatic mUlti-pattern metering , the
light value of the darker parts is also measured , resulting in a
well-balanced exposure. In addition , overall bright scenes, such
as snow scenes, come out correctly exposed with automatic
multi-pattern metering . What happens is that extreme bright-
ness is uniformly reduced to EV 16-1/3, automatically making
the right amount of , exposure compensation for correct
exposure.
