Histogram Function
The histogram is a graph that allows you to check the brightness
of the image. The greater the bias toward the left in the graph, the
darker the image. The greater the bias toward the right, the
brighter the image.
If the image is too dark, adjust the exposure compensation to a
positive value. Similarly, adjust the exposure compensation to a
negative value if the image is too bright
(p. 52) .
