The ExposureControl gives apps additional control over the exposure settings on a device.

To set an exposure value, call SetValueAsync. To turn auto exposure on, call SetAutoAsync.

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

If the device does not support the ExposureControl, you can still use the Exposure property on the VideoCaptureDevice to set the exposure value.

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

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