A spherical enclosure for a camera, has in some examples, an optically transmitting wall, a highly-reflective external surface, a coated internal surface, a collapsible internal lining, and a support tube. The wall may have a region of varying wall thickness providing a lens. The collapsible internal liner is made of a material that obscures the camera's silhouette, and is inserted through an opening in the wall while folded, and then expands into position. The inner surface of the enclosure may be coated with a material that reduces internal reflections. The camera, when mounted in the enclosure has the optical center of the camera coincident with the geometric center of the spherical enclosure, so that distortion of the camera image is minimized.
