Using the preset white balance settings
The camera provides two preset white balance settings,
for instant shooting with approximately the correct
adjustment.
There are also particular shooting conditions under
which the preset values may give better results than the
human eye adjustment.
1 Set the WHITE BAL switch to PRESET.
2 Set the FILTER control.
The white balance is automatically adjusted for
3200 K when the FILTER control is in position 1
or 2, and for 5600 K in position 3 or 4.
Hints on white balance adjustment
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
lights 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.

Using the ATW (Auto Tracing White
balance) function
The ATW function continuously adjusts the white
balance automatically to adapt to changes in lighting
conditions.
Depending on the shooting conditions, automatic
adjustment may not necessarily give optimum results.
For the best possible results, use the WHITE 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, turing the indicator off.

Correct adjustment of the black balance is important
for optimum operation of a video camera. It is
necessary when using the camera for the first time or
after a significant period out of use, and also when
there has been a sudden change in temperature.
The adjustment value is saved in memory, and
readjustment is not normally necessary after powering
the camera off or simply when lighting conditions
change.
