The Harbor Digital Design Ultimate Light Box Flash Diffuser Kit for the Nikon SB-900, SB-910 Flashes is a flash diffuser system for handle or shoe mount flash units. Designed as a modular system with the features of a larger studio soft box, it allows for multiple layers of diffusion to control the softness of the light.
The Light Box can be used with the small Half Dome diffuser inside, and/or with the supplied Lee Diffusion Filter installed in the front lens. These can be used to produce soft, studio quality light from your flash. It also comes supplied with an internal reflector, which can be used to direct more light forward when using the Light Box as a large bounce-type diffuser.
