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.
