An apparatus such as a head-mounted display (HMD) may have a camera for capturing a visual scene for presentation via the HMD. A user of the apparatus may be operating a second, physical camera for capturing video or still images within the visual scene. The HMD may generate an augmented reality (AR) experience by presenting an AR view frustum representative of the actual view frustum of the physical camera. The field of view of the user viewing the captured visual scene via the AR experience is generally larger that the AR view frustum, allowing the user to avoid unnatural tracking movements and/or hunting for subjects.
