Arial fireworks displays make great photos, and
they're relatively easy to do with either a film camera or a digital
Here's what you have to do:
Use a tripod. Absolutely essential, you can't hold
your camera steady for the long exposures (1 second to 30 seconds) that
give the best results of arial bursts
Choose the right spot. You want a clear view of the
sky, without any lights in the foreground (the long exposure you will make
allows foreground lights to burn in pretty heavily)
Set your camera manually. You'll be using long
exposures to capture 1 or several bursts.
Use a self-timer or cable release so you don't shake
Manually focus or set the camera to infinity (the
"landscape" mode on many digital models)
Turn off the automatic flash.
