There is not much needed for taking the pictures. Just this:
- Camera that has manual settings
- Tripod
If your camera supports it, you can also include:
- A remote shutter release
A remote shutter release for digital is like the cable release. Any inexpensive "off brand" is usually fine. Practice using it first before going out on the 4th.
Using a tripod is key, because you're going to be taking exposures that are 2 - 4 seconds long and the camera must remain completely still while the shot is taken.
You'll need to be able to manually set the exposure (shutter speed), Aperture (the f-stop), and ISO.
Depending on your camera and how close you are to the fireworks, you will need to adjust the f-stop to fine tune the pictures.
Longer exposures will capture multiple fireworks bursts. 2 to 4 second exposures work great.
ISO is the 'film' speed that the camera is using. In digital cameras the electronic pickup can capture images at various speeds.
You'll want to use a low ISO value, around 80 - 200. Although most cameras can shoot at higher ISO's such as 1000, the images will have more 'noise' and look 'grainy'.
The photos in this project were taken using an ISO of 125.
Pick a low ISO and stick with that. If you find that the photo is underexposed, adjust the aperture.
The larger the f-stop number, the smaller the iris is open.
What aperture to use depends on your camera, and how close you are to the fireworks.
You will most likely need to adjust this setting. Take some shots at around f-8 and if they look to be underexposed use a lower value. Overexposed then use a higher value.
The photo here was at f-11 and is under-exposed.
I found that f-5 worked for me.
A 2 - 4 second exposure will get good shot.
I used an exposure of 4 seconds for the pictures in this project.
The main thing to keep in mind is when you press the shutter release, the camera has to stay completely still. If you bump it during the exposure, it will blur things.
If you are using a film camera, a cable release or bulb that attaches to the shutter release can be used. It will allow you to press the button without shaking the camera, and you can hold it for any desired length of time.
If you want multiple fireworks in one shot, usually the other lit parts of the frame are badly overexposed, especially if you use longer exposures than just a couple of seconds... Just cover the lens with something like black foam rubber but just make sure that it covers enough beyond the lens. And be careful not to touch and shake the camera while doing that. Then simply take it away snappy when you see more fireworks shooting up.
And you can use the cameras self timer... (to prevent bumping the camera when pushing the shutter release).
One method used is when you hear the "thump" of the firework being launched you hit the trigger, and release when the firework has burned out. The only problem with the "thump" method, is if you are a good distance from where the fireworks are being set off you will end up missing the tracer trail of the fireworks as they climb into the sky. Sound travels at about 1000 ft/sec, and light travels at about 190,000 MILES/sec. However, it will catch it before the fireworks go off.
