My son wanted a cool shot of him playing soccer, so we came up with this during an improvised 5 minute shoot.
This is shot with my 5D2 and the 17-40 (17mm, ISO100, f/4, 1/4000). The secret to a shot like this is a trampoline and the magic of High Speed Sync. I used a Pocketwizard TT1 with AC3 on the camera to trigger two bare 580EXII's with Pocketwizard TT5's. Both flashes are to camera right just outside the frame and at full power.
Because we had rather limited time, we opted for shooting the ball and my son separately and composite them together in Photoshop.
