This event is triggered when the hardware shutter button is pressed and held for approximately 800 milliseconds.

To account for the Windows Phone execution model, add the event handler for this event in the OnNavigatedTo(NavigationEventArgs) method. To help release memory related to the camera, remove the event handler for this event in the OnNavigatingFrom(NavigatingCancelEventArgs).

This event can also be used for capturing video. When capturing video, the CaptureSource..::.Start method must be called prior to the hardware shutter button press. If the capture source has not started, this event will not fire.
