The first thing is you have to prepare your equipment and your camera. Get a good quality tripod with a rotating head that can move quickly and smoothly enough. This is so the camera will not shake the captured image when moving from object to object quickly.
Turn off all of your “auto" settings on your camera because these will just go haywire once the mock bombs begin flying into the sky. Something like auto focus would not know which one to focus on and almost all images would end up at least partially out of focus.
You may also want to use a wide angle lens so you can get in the most light as possible.
