Histogram Function
The histogram is a graph that allows you to judge 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 dght, the
brighter the image.
If the image is too dark, adjust the exposure compensation to a
positve value. Simtady, adjust the exposure compensalon to a
negative value if the image is too bright (p. 44).
