Understanding Brightness
If the image is normal in brightness with no extremely bright or dark
portions, 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.
Dark image
When the image is underexposed, the part to the left is cut off (dark
portions) and when the image is overexposed, the part to the right is cut
off (bright portions).
This camera can warn for bright portions by red flashing in shooting and
in playback.

Understanding Color Balance
Distribution of color intensity is displayed for each color in RGB
histogram display.
If a color is partially cut off on one side, it indicates that the color is under-
or overexposed, that the light is very weak or strong in that color, or that
the white balance is incorrect.
