This one was tricky. I had to do a rear sync to capture the fire trail and freeze the motion, however with the Canon 5DMK2 and Pocket Wizards you cannot use the rear curtain. So my workaround is to use the Canon 580 speed light on the camera at a very low power and point it at my Alien Bee (the 580 can do rear curtain). The 580 flash fires the Alien Bee.
My assistant ran around with a sparkler and this was the outcome!
