ABSTRACT:
A photographic lighting apparatus has a light gun with a handle and nose in which a light source is mounted, and a light guide projecting from the nose for directing a narrow beam of light from the source. The light guide has a coupling mechanism such as screw threads on its free end, and a hollow hood member is securable to the light guide via corresponding internal screw threads at one end. The hood member is of larger dimensions at its opposite end to spread the light beam, and is arranged for selectively mounting any one of a number of light controlling plates in the light beam intermediate its ends. Other hood members of different shapes and dimensions may be provided.
