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.
