The reason that snappy cameras tend to produce photos that look like cardboard cutouts is that the flash is so close to the lens that shadows all move away from the center of the shot. This is also the main reason for red-eye in photos. The flash is seen reflected in the eye.
The idea behind a flash bracket like the FL-BK is that by moving the flash away from the lens the light will look more natural more professional results can be seen instantly. You can see this on any news channel, every paparazzi will be using one.
In order to take advantage of this you will need a camera with an external flash. Typically an SLR with a hotshoe mounted flashgun.
The FL-BK features fittings for both the hotshoe of the flash and the camera body itself. Both are sturdy and once tightened will allow you to confidently hold it all in one hand. With the added advantage of looking like a pap and being able to get into various events and parties. Really, try it. Mount your camera and flash on one of these and just walk right in saying 'I'm a photographer'. You'll be surprised.
On the downside, the FL-BK does not incorporate a hotshoe extension cord meaning that unless you use a wireless flash system such as Nikons i-TTL you will need to mount a separate cable between the flash and the base, and then to the camera. Its not a big deal but worth considering. Is it worth it to move your flash so little?
For me, its a handy thing to have in the camera bag and know it's there if i need to carry a flash around on a cord but have a hand free, but i use it less and less. Opting for handheld flash placement for ease of use and versatility. That said. If you want one, i cannot recommend this one enough.
I picked mine up for £15 and it does its job, its weighted very nicely and the grip is easy and comfortable to hold. Finished in piano black it looks cool too and goes with my camera nicely. The screw mount for holding the camera can be moved along a slit in the base to fit different widths and preferences and the soft base holds the camera firmly and without damage.
If you see one of these cheap i'd pick one up, especially if your new using external flashes.
