Arrange a white subject (paper, cloth, etc.) under
the same lighting conditions as for shooting, and

The adjustment value is automatically saved in
memory A or B as selected above.
To save the white balance adjustment for different
lighting conditions, repeat steps 2 to 4 above. You can
save two different values for the white balance, in
memories A and B.
Note
When using a camera control unit or remote control
unit, if the W/B BALANCE switch of the control unit
is set to PRESET or MANUAL, it is not possible to
carry out white balance adjustment on the camera.
To recall a white balance value from memory
Before beginning shooting, set the W. BAL switch to
the A or B position. This automatically sets the
camera to the white balance adjustment saved in the
corresponding memory.
If white balance adjustment cannot be
completed automatically
The warning message “AUTO WHITE -NG-” appears
in the viewfinder.
Make the necessary corrections, then carry out the
process again.

Using the Preset White Balance
Settings
The camera provides two preset white balance settings,
for instant shooting with approximately the correct
adjustment. The preset white balance can be selected
between 2200 K and 4300 K when the FILTER control
is set to 1 and between 4600 K and 12000 K when the
FILTER control is set to 2, 3 or 4 (see page 59).
There are also particular shooting conditions under
which the preset values may give better results than the
human eye adjustment.
1
Set the W. BAL switch to PRESET.
2
Set the FILTER control.
The white balance is automatically adjusted for the
preset white balance selected in basic menu page 2
(see page 59).
Light Sources and Color
Temperature
Adjustment of the white balance to match the light
source is essential to ensure correct color rendering.
The color of a light source is indicated as a color
temperature in kelvins (K). It is higher for bluish light,
and lower for reddish light. When the camera is
shipped it is adjusted for use with video lights (halogen
lamps with a color temperature of 3200 K). For use
with other light sources, therefore, adjustment is
required.
First use the FILTER control to set the approximate
color temperature, then carry out white balance
adjustment.
The following table shows typical color temperature
values for different light sources.
WHITE:PRESET
The W. BAL switch is in the PRESET
position.
Move the W. BAL switch to the A or B
position.
The camera is outputting a color bar
signal.
Move the OUTPUT/DL/DCC+ switch to
one of the CAM positions.

Using the ATW (Auto Tracing
White Balance) Function
The ATW function continuously adjusts the white
balance automatically to adapt to changes in lighting
conditions.
Note
Depending on the shooting conditions, automatic
adjustment may not necessarily give optimum results.
For the best possible results, use the W. BAL switch.
To use the ATW function
Press the ATW button turning the indicator on.
This activates the ATW function, and the ATW
indication appears in the viewfinder.
To disable the ATW function, press the ATW button
again, turning the indicator off.
