Using exposure compensation
In difficult lighting conditions, you can use Exposure
Compensation to override the automatic exposure setting that
the camera makes. Exposure Compensation settings range
from -3.0 EV (Exposure Value) to reduce the exposure of the
image (darkening it), to +3.0 EV to increase the exposure of
the image (brightening it).
By default,
Exposure Compensation
is set to 0 (zero) and no indication is
given on the active display. When
Live View is turned on and you press
the buttons on the Controller ,
a meter appears in the middle of the
active display, and the Exposure
Compensation value is shown on the
bottom of the display.
When you have not changed
Exposure Compensation for
2 seconds, the meter disappears,
but the value remains at the bottom
of the screen flanked by arrows
(unless it has been set to 0).
