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.
