Adjusting White Balance Settings

White balance is normally compensated for by the automatic white balance gain control. In some lighting conditions, you may need to manually adjust the red and blue settings for optimal viewing.

When Automatic White Balance is enabled, the red and blue setting values are based on feedback from the camera. When Automatic White Balance is disabled, the camera uses the red and blue setting values to control the white balance. When Automatic White Balance is first switched from On to Off, the red and blue values displayed are based on the current feedback from the camera. The red and blue values range from 0 to 511. Changes occur in increments of 5.

The following chart illustrates the red and blue settings relationship to white balance.
