Here are some sample shots from London of the new PowerSnoot™. The PowerSnoot is not only a high-power intensity booster, for shooting telephoto images with on-camera flash (like wildlife or sports) but taken off the camera it gives really cool, dramatic lighting. It is totally the complete opposite of the Lightsphere®, which spreads light everywhere.
For these images, I used a Canon 5D with a 135mm f2.0 lens, and a STE-2 transmitter simply firing into a 430EX flash.
