4 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.
