ABSTRACT:
A photographic light comprises a main reflector with a light aperture, which is closed by a diffuser, and light sources, arranged in the photographic light casing and emitting luminous rays that reach the diffuser. A portion of the diffuser is exposed to the luminous rays of at least one second light source which reach the diffuser in addition to the luminous rays of at least one first light source. The additional second light source creates an area of increased light concentration at the diffuser. During the photographic step the photographic light is arranged such that the mat gloss objects to be photographed are positioned in the area of the increased light concentration, thereby generating strong reflections at the mat gloss surfaces, which are easily discernable from the surrounding areas.
