About the Histogram
The histogram is a graph that allows you to
judge the brightness of the shot image.
The greater the bias toward the left in the
graph, the darker the image. The greater
the bias toward to 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. 76).
