A histogram shows the brightness
distribution of an image.
The horizontal axis represents
brightness (dark at the left and bright
at the right) and the vertical axis
represents the number of pixels.
The shape and the distribution of the
histogram before and after shooting
tell you whether the exposure level
and contrast are correct or not, and lets you decide if you need to adjust
the exposure and take a picture again.

When the image is underexposed, the part to the left is cut off
(underexposed portions with no detail) and when the image is
overexposed, the part to the right is cut off (overexposed portions with no
detail).
This camera can be set so that it displays the Bright/Dark Area warning
during Capture or Playback mode.

Distribution of color intensity is displayed for each color in the RGB histogram.
The right side of the graphs look similar for images that have the white
balance adjusted well. If only one color is lopsided to the left, that color is too
intense.
