The Lightsphere mounts to the flash with the head straight up. Light is diffused over a large area. As can be seen, the light on the model now becomes almost flat. Much of the direction of the light is lost due to the design of the Lightsphere. However, lighting on the face is very "gentle" and the intensity and definition of the shadow is greatly reduced. This photo illustrates a disadvantage of the Lightsphere. It does reduce output of the flash. This photo is darker than the others, even with the brightness increased slightly in Photoshop. About 1 stop larger on the aperture and / or about a 1EV increase in flash power takes care of the problem. In theory, a TTL flash should take care of the light loss automatically, but I never found that to be the case. I would always add 1EV to my Canon 580EX flash when using the Lightsphere, and exposures were always more accurate.
