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 let you decide if you need to adjust the
exposure and take a picture again.

Understanding Brightness
When the brightness is correct and there are no overexposed or
underexposed areas, the graph peaks in the middle. If the image is
underexposed, the peak is on the left side, and if it is overexposed, the
peak is on the right side.
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.
