Adjusting White Balance
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. The following illustration depicts
the relationship between the red blue settings to white balance.
