3. Taking photographs with exposure compensation
When the correct exposure cannot be obtained for the primary subject
due to extreme differences in brightness between the subject and back-
ground, or when deliberate over or under-exposure is required, exposure
can be compensated using the three methods described below.
<1. Setting exposure compensation manually (with Av, Tv, P)>
Turn the F dial to set the amount of exposure compensation.
Compensation may be set in 1/3 EU steps within a range of +3EV~-3EV.
Exposure mode
Aperture priority auto (Av)
Shutter priority auto (Tv)
Program auto (P)
Example : Setting a compensation
value of -2/3EV.

" " The exposure compensation may be set to remain until cleared (page 88).
" " Press the "LIGHT" button while turning the F dial to prevent exposure compensation
being changed accidentally (page 88).
" " Exposure compensation is changed in half-steps (page 87).

The set compensation appears in the
display panel, and the compensation
and the "+/-" mark are displayed in the
exposure meter in the viewfinder.
• Always return the exposure compensation
value to "0" when photography is complete.
The exposure compensation remains until
the main switch is turned OFF.
• Be careful to ensure that the compensation
value is not changed accidentally.
• See page 56 for details of the exposure
compensation display in the manual expo-
sure mode.
Example
When the subject is lit from behind
Compensate within the range of "+1/3
EV or +1/2 EV to +3 EV".
In the average metering mode, when
the percentage of the picture occupied
by a bright background is large (for
example people with a light, a bright sky
or the sea behind them, people in front
of a window, etc.), the people tend to be
(+ compensation)
under-exposed and appear as dark sil-
houettes. In such cases, compensate
the exposure within the range of +1/3
EV or +1/2 EV to +3 EV to increase the
exposure on the main subject.
(no compensation)
When the background is dark
Compensate within the range of "-1/3
EV or -1/2 EV to -3 EV".
When the percentage of the picture
occupied by a dark background is large
(people standing in spotlights, etc.), if
the photograph is taken in the average
metering mode the people tend to be
over-exposed. In such cases, compen-
sate the exposure within the range of -
(- compensation)
1/3 EV or -1/2 EV to -3 EV to reduce the
exposure.
