## Application Structure

Most of the QML code supports the user interface for this application with the camera types being mostly found in declarative-camera.qml and CaptureControls.qml.

CaptureControls, which is implemented in CaptureControls.qml, generates a column on the right hand side of the screen which includes control buttons for focus (not initially visible), capture, flash modes, white balance, exposure compensation, and if a preview is available, a preview button. The last button exits from the application.
