OTHER RECORDING FUNCTIONS
Exposure Compensation (EV Shift)
Exposure compensation lets you change the exposure
setting (EV value) manually to adjust for the lighting of your
subject. This feature helps to achieve better results when
recording a backlit subject, a strongly lit subject indoors, or
a subject that is against a dark background.
EV Shift Range: –2.0EV to +2.0EV
Steps: 1/3EV
1.
In the REC mode, press [MENU].
2.
Select the “REC”tab,
select “EV Shift”, and
then press [왘].

3.
Use [왖] and [왔] to
change the exposure
compensation value,
and then press [SET].
•Pressing [SET] registers
the displayed value.
Up : Increases the EV value. A higher EV value is best
used for light-colored subjects and backlight
subjects.
Down : Decreases the EV value. A lower EV value is best
for dark-color subjects and for shooting outdoors
on a clear day.

OTHER RECORDING FUNCTIONS
•To cancel EV Shift, adjust the value until it becomes
0.0.
4.
Record the image.
IMPORTANT!
•When shooting under very dark or very bright
conditions, you may not be able to obtain satisfactory
results even after performing exposure
compensation.
NOTES
•Performing an EV shift operation causes the
metering mode to switch automatically to center
weighted metering. Returning the EV shift value to
0.0 causes the metering mode to change back to
multi-pattern metering.
•You can use key customization (page 85) to
configure the camera to perform exposure
compensation whenever you press [왗] or [왘] while in
the REC mode.
Adjusting White Balance
The wavelengths of the light produced by various light
sources (sunlight, light bulb, etc.) can affect the color of a
subject when it is recorded. White balance lets you make
adjustments to compensate for different lighting types, so
the colors of an image appear more natural.
1.
In the REC mode, press [MENU].
2.
Select the “REC”tab,
select “White
Balance”, and then
press [왘].
67
OTHER RECORDING FUNCTIONS
3.
Use [왖] and [왔] to select the setting you
want, and then press [SET].
NOTES
•Selecting “Manual”changes white balance to the
settings achieved the last time a manual white
balance operation was performed.
•You can use the key customization feature (page 85)
to configure the camera so the white balance setting
changes whenever you press [왗] or [왘] while in the
REC mode.
When shooting under these conditions:
Normal conditions
Outdoor daylight
Shade
Incandescent light bulb
(reddish tinge)
Fluorescent light (greenish tinge)
Difficult lighting that requires manual
control (See “Adjusting White Balance
Manually”.)
Select this setting:
Auto
Manual
Adjusting White Balance Manually
Under some light sources, automatic white balance under
the “Auto”setting can take a long time to complete. Also,
the auto white balance range (color temperature range) is
limited. Manual white balance helps to ensure that colors
are recorded correctly for a particular light source.
Note that you must perform manual white balance under
the same conditions you will be shooting under. You must
also have a white piece of paper or other similar object on
hand in order to perform manual white balance.
1.
In the REC mode, press [MENU].
2.
Select the “REC”tab, select “White Balance”,
and then press [왘].
3.
Use [왖] and [왔] to
select “Manual”.
•This causes the object
you last used to adjust
manual white balance to
appear on the monitor
screen.

Point the camera at a white piece of paper or
similar object under the lighting conditions
for which you want to set the white balance,

•This starts the white balance adjustment procedure.
The message “Complete”appears on the monitor
screen after white balance adjustment is complete.
•Dim lighting or pointing the camera at a dark colored
object while performing manual white balance
adjustment can cause the procedure to take a long
time to complete.
5.
Press [SET].
•This registers the white balance settings and returns
to the REC mode.
