3 Some sample histograms are shown below:
• If the image contains objects with a wide
range of brightnesses, the distribution of
tones will be relatively even.
• If the 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.
A Playback Zoom
To zoom in on the photograph when the
histogram is displayed, press
X. Use the X and
W buttons to zoom in and out and scroll the
image with the multi selector. The histogram will
be updated to show only the data for the portion
of the image visible in the monitor.

Camera histograms are intended as a guide only and may differ from
those displayed in imaging applications.
