Before Using Your Camera
1
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
tells 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.

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