Histogram Function
The histogram is a graph that allows you to check the brightness of
an 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. 135).
