The Gary Fong LSU-CLOUD Lightsphere Universal Inverted Dome Cloud Flash Diffusion System is a large, round, soft and flexible diffuser that slips over the front of any standard shoe mount flash unit. The inside of the Lightsphere is completely textured to make the light dispersion even more "soft" than it would be otherwise. And because of this design, it is possible to make the material more translucent, keeping the unit from losing a lot of light while actually increasing the diffusion and softness of light.
