4 Some sample histograms are shown below:
• Ifthe image contains objects
with
a
wide range
of
brightnesses, the
distribution
of
tones will be
relatively even.
• Ifthe image
is
dark, tone
distribution will be shifted
to
the
left.
•
If
the image
is
bright, tone
distribution will be shifted
to
the
right.

Increasing exposure compensation shifts the distribution
of
tones
to
the
right, while decreasing exposure compensation shifts the distribution
to
the left. Histograms
can
provide a rough idea
of
overall exposure when
bright
ambient lighting makes
it
difficult
to
see
photographs in the
monitor.

from
those
displayed in

applications.
