Adjusting the Black Balance and the White Balance
55
Chapter 3 Adjustments and Settings for Shooting
The switch returns to the center position, and
the adjustment is executed.
During adjustment, the message “WHITE :
OP” is displayed on the viewfinder screen (in
display mode 2 or 3).
The white balance adjustment ends in about
one second with the message shown in the
following figure, and the adjustment setting
is automatically stored in the memory (A or
B) that was selected in step 1.
Note
If the camera has a zoom lens with an automatic iris,
the iris may hunt
1)
during the adjustment. To
prevent this, adjust the iris gain knob (indicated as
IG, IS, or S) on the lens.
For details, refer to the lens operation manual.
1) Hunting: Repeated brightening and darkening of
the image, resulting from repeated response to
automatic iris control.
If the automatic white balance adjustment
cannot be made
If the white balance adjustment cannot be
completed normally, an error message will appear
for about 3 seconds on the viewfinder screen.
Possible messages are listed below.
If any of the above error messages is displayed,
retry the white balance adjustment. If the error
message occurs again, an internal check is
necessary.
For information about this internal check, refer to
the Maintenance Manual.
If you have no time to adjust the white
balance
Set the WHITE BAL switch to PRST.
This makes it possible to automatically set the
white balance to 5600K (factory default value) by
pressing the COLOR TEMP. button.
The color temperature to which the white balance
is set when the COLOR TEMP. button is pressed
can be selected from among 3200K, 4300K,
5600K, and 6300K on the ASSIGNABLE SW
page of the OPERATION menu. You can also
assign color temperatures to the ASSIGN 1/3/4
switches and the RET button on the lens.
For details of automatic white balance adjustment,
see page 54.
