"Gary Fong WhaleTail flash diffuser is a good device. It gives you more control over the light than many other translucent flash diffuser on the market today... Although the design of the WhaleTail is good it does have some drawbacks: not being able to fold flat, heavy weight, plastic flaps mount... "

I'm a user of the Gary Fong Whale Tail Reporter, and while it seems a bit hard to manage at first, having taken a few test shots with it, I'll tell you this: It works as advertised and I keep it on one of my flash heads pretty much all of the time. You will have to make exposure compensations before hand, but that's just a matter of fact. Definitely the way to go if you want the nice even lighting of a lightsphere I/II AND a strong connection between the diffuser and the flash. Bought one and have not been dissapointed with the results.
