More often than not, we find that the pictures of fireworks are grainy, blurred, or over/under exposed. In order to avoid such disappointments, you need to get the equipment and technique right.
Securing the camera to a tripod eliminates any movement made by the camera and ensures that the movement of the fireworks is the only movement captured by the camera. Using a tripod will ensure that the images are crisp and clear rather than shaky or blurred.
While shooting fireworks, the camera shutter has to stay open for a longer time to increase the light exposure, hence, use a cable release that helps the cameraman trigger the shutter without wavering or shaking the camera.
Before you begin shooting, hunt for the best possible location wherein your view won't be obstructed by spectators or other obstacles.
Look through the viewfinder during the initial few bursts to know the exact location of the action and set the camera pointing in that direction. Framing will also help you anticipate the right time for the shooting the fireworks.
Though zoomed-in shots offer a wide palette of color and are quite effective, preferably, shoot at wider focal lengths than tighter shots. Set the focal length to infinity, except when you want a close-up shot. Remember to include buildings/people in the background.
If this feature is not available in your camera, you would have to manually adjust the settings. ISO 100 should serve the purpose for good clarity and finer grain snapshots.
You can use the bulb mode to shoot fireworks as it allows to hold down the shutter till the fireworks have finished exploding. Experiment with a range of shutter speeds to get varied results. You can even experiment with multiple burst shots using a black hat or card sheet in between the bursts.
Some of the biggest 4th of July pyrotechnic celebrations across the US offer great opportunities for firework photography.
