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.

1 Make the following settings on the camera.
•POWER switch: ON SAVE
•OUTPUT/DL/DCC+ switch: one of the CAM positions
•Lens iris selector: A (automatic)
•ATW button: off
2 Set the FILTER control according to the lighting conditions. (See page 39.)
3 Set the W. BAL switch to A or B.
4 Arrange a white subject (paper, cloth, etc.) under the same lighting conditions as for shooting, and zoom in on it so that as far as possible the whole screen is white.
The minimum white area requirements for the adjustment are shown in the following figure.
Area of white within this rectangle should be
Center of the screen equivalent to at least 10% of the image area.
