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. 101).
