Histogram
The histogram is a graph that allows you to check the brightness of
an image. You can also display the histogram in the , ,
and modes to check the brightness while shooting. 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. 41).
