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