Abstract: A device for influencing light for illuminating a set for filming, photography, theater and/or stage includes a frame and a first carrier layer mounted on the frame. The first carrier layer is essentially transparent to the light used for illuminating the set. At least on selected areas of the first carrier layer, a layer of a material which is impermeable and/or partially permeable to the light used for illuminating the set is arranged.

Abstract: A portable light reflector or diffusor includes a reflection or diffusion cloth attached to a foldable framework composed of longitudinal struts and a transverse strut which is stiff with respect to compression and connects the two longitudinal struts, wherein the transverse strut has ends bent in the direction towards the plane defined by the longitudinal struts and the reflection or diffusion cloth attached to the longitudinal struts, wherein the angle between the bent ends and the intermediate piece between the ends is greater than 90°. A belt extends parallel to the transverse strut in such a way that the longitudinal struts are pressed apart for tensioning the reflection or diffusion cloth.
