Remarks

The WhiteBalanceControl gives apps additional control over the white balance settings on a device. You can use one of the ColorTemperaturePreset values by calling SetPresetAsync. Or call SetValueAsync to set a specific Value between the Min and Max.

You can find out if a device supports this control by checking WhiteBalanceControl.Supported.

If the device does not support the WhiteBalanceControl, you can still use the WhiteBalance on the VideoCaptureDevice to set the value for the white balance color temperature.

You can access the WhiteBalanceControl for the capture device through MediaCapture.VideoDeviceController.

White balance is specified as a color temperature in degrees Kelvin.

For how-to guidance for using the FocusControl, see Manual camera controls for photo and video capture.
