234 Photo Information
D Histograms
Histograms show tone distribution. Pixel brightness (tone) is plotted on the
horizontal axis and the number of pixels on the vertical axis.
• If the picture contains objects
with a wide range of
brightnesses, the distribution of
tones will be relatively even.
• If the picture is dark, the
distribution will be shifted to the
left.
• If the picture is bright, the
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 pictures in the monitor.
D The Histogram Display
• RGB histograms show tone distribution.
• Camera histograms may differ from those displayed in imaging
applications. Use them as a guide to actual tone distribution.
