Abstract
Abstract A device for side-lighting a subject placed in front of a background as well as for lighting the background itself, for example when taking pictures of the subject by photography, cinematography or the like, consists of a series of reflecting panels attached to a solid or hollowed-out common central background wall or attached to each other around a free surface corresponding to the rear end-wall of the assembly. These reflecting panels are disposed in raised and inclined positions with respect to the background plane of the assembly in orientations such that said panels are capable of reflecting the light emitted by a front light source towards the subject to be photographed as well as towards the rear end-wall of the assembly, the assembly being of generally concave shape.
