Adjustments and Settings for Recording : Adjusting the White balance and Black Balance
Adjustments and Settings for Recording
To record high-quality video with the unit, the black and white balances must be adjusted according to conditions.
For higher quality, it is recommended that the adjustments should be made in this order AWB (white balance adjustment) >
ABB (black balance adjustment) > AWB (white balance adjustment).
Whenever light conditions change, the white balance must
be re-adjusted.
To adjust the white balance, follow the steps below.
1 Set the switches as illustrated below.
2 Adjust the CC/ND FILTER control according to
the light conditions.
> For examples of CC/ND FILTER adjustments, see
[Shooting and Recording/Playback Functions
Section] (page 21).
3 Place a white pattern at a point where the light
conditions match those for the light source of
the subject.
z Then zoom-in on the white pattern so that white color
appears in the screen. A white object (cloth or wall)
may be used instead of a white pattern.
