Dano, the guys are right, it's pretty tough getting pictures of the light show. I've had my best luck setting my camera on the "sport" mode. The one that will take pictures, one after the other, as long as you hold the button down. In doing this the guessing game gets a bit easier. Try to anticipate and hit the button. Or, once a flash goes off, hit the button and hope another comes along pretty quick. the one draw back is that it drains your memory pretty fast. But, you can delete the blank pictures just about as fast as you get them.
