This setting allows you to adjust the brightness of the Image
Display. You can use this setting to increase the brightness
for harsh lighting environments, or reduce the brightness to
extend battery life.
The default Display Brightness setting is Medium.
1. In the Setup Menu (see page 113), select Display
Brightness.
2. Use the buttons to highlight
a setting. The new setting is
applied to the Live View screen
behind the menu so you can see
the effect the setting will have.
3. Press to save the setting and
return to the Setup Menu.
The new setting remains in effect until it is changed again,
even when you turn the camera off.
