Abstract
A light shading device for a camera in which a soft and elastic light shading curtain has a base part which is fixed on a flat support surface, in the region of the shutter running path. The free end of the shading curtain is brought into elastic contact with the shutter curtain by way of a step provided on the support, the step serving to incline the free end of the light shading curtain with respect to the support surface.
