Specification :
The Gary Fong WhaleTail Reporter Flash Diffuser is a multi-purpose, all-in-one flash diffuser that fits virtually any shoe- or handle-mount flash. Its innovative mounting design provides a secure and adjustable grip to any flash head, from a Nikon SB-600 to a Metz 45 handle mount. This means there's only one model you need to buy, ever.
The WhaleTail is a multi-purpose diffuser. It is the first diffuser ever to offer rear-wall bouncing. For ultimate softness, the rear panel flips up to provide an open back, which allows the light to bounce off a rear wall. Or, for standard bouncing, the top flap lifts up to allow for ceiling bouncing. Or keep both flaps closed, and use the forward curved design for more power.
The WhaleTail also features a slot at its base for optional colored filters. This allows for warming, cooling, or special effect experimentation of the light output of the flash.
