White Balance Adjustment; Saving An Appropriate White Balance Value In Memory - Sony DXC-D30WSP Service Manual

White Balance Adjustment

Adjusting the white balance ensures that as lighting
conditions change white objects remain white in the
image and tones remain natural.
The color of light emitted varies from one light source
to another, and as the lighting changes the apparent
color of an illuminated subject changes. It is therefore
necessary to adjust the white balance each time the
principal lighting source changes.
Saving an Appropriate White
Balance Value in Memory
You can save two white balance values in separate
memories, A and B. Unless changed, the saved values
are retained for approximately ten years, even when
the camera is powered off.
Once a value is saved, you can automatically restore
the adjustment by moving the W. BAL switch to the A
or B position. This makes shooting under alternating
lighting conditions easy.
Separate white balance values for each
FILTER control setting
In the default case, as described above, the same two A
and B white balance values apply to all settings of the
FILTER control. It is possible, however, to change the
AWB MEM menu setting (see page 58) so that there
are eight possibly different values for each of the A
and B positions and for the four FILTER control
settings.
