An object to be photographed is illuminated with substantially omni-directional, glare-free lighting. The object is placed within an ovoidal shell, inward from an access opening at one end, and supported on a platform formed by a flattened bottom surface of the shell. The entire inner surface of the shell is a light-diffusing surface and is illuminated by a light source which is shielded from direct illumination of the object. The ovoidal diffusing surface reflects light back and forth from and onto itself to produce substantially uniform omni-directional illumination within the shell. The object is supported far enough inward from the access opening of the shell to receive such omni-directional illumination so that it is well lighted for photographing and, in the absence of direct-lighting illumination, appears substantially glare-free. Any highlights desired for photographic purposes are produced by direct lighting from a suitable source, as by controlled direct lighting from the main light source or from a supplemental lamp.
