An optical diffusion unit includes a diffusing member 1 that can obscure the flash lamp B to scatter light passing through it, a supporting member 2 with light shielding means such that stray light exiting the diffuser may not then directly enter any optical sensors C on a camera A, and attachment means for attaching the unit to the flash lamp window B of a compact stills camera A. The diffusing member 1 may be moved away from the flash lamp window B whilst remaining attached to the camera A. The diffusing member 1 may have properties for reducing the amount of high frequency blue light passing through it. The unit is intended for use on domestic compact stills cameras with built in flash lamps. It results in the reduction of overexposure and shadow contrast when taking photographs on compact stills cameras with the flash turned on. |
