When shooting fireworks, a good mantra to follow is: slow and steady. Try to capture the event with a very slow shutter speed. In this series of photographs, my shutter speed varied from 1/5 second to 1 second. “Steady” can be achieved in several ways. If you have a tripod, use it. If not, try to find a tree, fence or something very solid. Brace your camera, lower your shutter speed and experiment. Wait for the firework burst of light and depress your shutter speed. Good luck!
