This is one of many photos from Monday evening, July 4th holiday in the United States.   What worked for me is pretty normal stuff for fireworks shots.

• Tripod
• Low ISO (I used 100)
• Aperture of f/8 to f/16.  I used f/8 most of the time.
• Bulb exposure started when you want and released when you want.

A remote shutter release is nice, setting the camera for the zone of display and sitting back and pushing the shutter release when the shell starts up and holding for the burst.  This is to be played with. Timing here gave a palm tree effect.

In the photo shown, shutter was  held from just after the initial shot and ended directly after the burst.  There is a second one in there just ready to burst into sparkles.
