Abstract

A light source triggering device for use with a light source (3) to illuminate a scene being recorded by a moving picture camera (1). The light source triggering device comprises means to cause the light source (3) to emit at least one flash of light substantially in synchronisation with exposures of the moving picture camera (1) and to cause the light source to emit at least one additional flash of light between each pair of exposures of the moving picture camera (1).
