Exposure techniques for shooting fireworks
by Frederic Hore

The Montreal region is graced with many fireworks festivals and shows throughout the year, form the International Fireworks competition at La Ronde, to municipal displays celebrating assorted holidays. Then there are the famous New Year’s Eve Fireworks in Sydney Australia, and the Eiffel Tower in Paris, the Carnival Pyro-tecnics over the Baie des Anges during the Nice Carnival (France) and of course the Independence Day celebrations on the 4th of July in most of the major cities in the United Sates.

Fireworks are bright, almost as bright as a noon-time sun, so shoot as if you were shooting during the day. The exception will be what you do with your shutter speed. Here are some basic settings:

Auto focus – OFF!  Focus your lens at infinity and leave it there... its one less variable to think about! Besides, firework displays are usually (I hope!) more than 100 feet away from you, so even with a telephoto lens, focus is not an issue.

ISO 100/200 – Depending upon your camera model, set it to the lowest ISO setting. This is the optimum setting for most digital sensors for best quality. This will also lessen the chance of overexposure. Increasing the ISO will raise the sensitivity of the sensor thereby hitting it with more light, and progressively, will introduce more image noise too.

Aperture - On average start with f/11. If the light looks weak and faint, OPEN the aperture to f/8. If it's bright and lots of fireworks are exploding, close down to f/16 or f/22.

Shutter speed – set your camera to MANUAL MODE, then set your shutter speed to BULB for manual shutter control; then plug in a manual remote control. When the fireworks start, trip the shutter and count out loud - "one thousand and one, one thousand and two, one thousnade and three"  and so on... s-l-o-w-l-y, so that you achieve 2 seconds exposures for a full burst, or from 4 to 6 seconds if you are shooting with a wide angle lens and wish to fill the frame, or to capture more background details.

Watch the show and practice this technique so you get the rhythm right. Avoid using your camera’s fixed shutter speeds. If you do, you will be trying to manually change your shutter speed on the fly... in the dark... with all the explosions going off! You will find this method to be very time consuming... and frustrating!

White Balance –  set to Daylight/Sunny mode or 5400 degrees Kelvin (the Sun icon on your LCD display). If you want a sky that is more blue (to correct for light pollution), with city lights a more realistic colour, select the “Incandescent” mode. I have found, however, that the sunny setting is the best for rich and consistent colours. If you use Auto White, the colour rendiiton may change from shot to shot, without any consistency. Sunny is the way to go. Did I say SUNNY enough times?

Turn on the HIGHLIGHTS setting in your camera. In Nikon cameras, this is achieved by going to the Playback menu (arrow at top), then selecting "Display mode." Click on "highlight," then go to the top to “done” with the cursor, and press “enter” or OK. Other cameras may have a similar setting. Check you manual or camera menu for more details.

Next, upon reviewing your images, you want to scroll through the data screens on the your monitor until a little symbol flashes indicating it will show bright spots as flashing light. This will tell you if you have overexposed an image. On some Nikon cameras, this is indicated by a small flashing indicator marked “RGB.”

OK, now all you need to do is zoom in and compose your image. Of course during a 30 minute show, you will see small bursts and big ones, so your composition may need to be adjusted from shot to shot. From where you are positioned, when the show starts, set your zoom at one setting, take a few shots, then review your images quickly.

1. First check - are there any highlights flashing?

NO... then your shot is OK. Expect some flashing at the nucleus or center of the burst - this is normal as it’s the brightest point in an explosion.

YES - you are overexposing and will have to close your aperture (to f/11, f/16, f/22 or points in between). You may also have to shorten your shutter speed too. It is a combination of both. The aperture controls the amount of light, the shutter – the duration of the exposure.

2. If you photographed a burst and it was mainly red, or blue or green etc - are you seeing this correctly on the replay of your cams’s LCD monitor?

If YES - your exposure is correct!

If NO - and you are seeing mostly white, the colours are overlapping, though you may not have blown out the highlights. You will have to close down the aperture again to f/11, f/16 etc, or reduce your shutter speed.

3. The explosions are happening fast and furious, and all you are seeing are images that are  white! white! white!

Question : What colour do you get when you combine red, blue and green? You get - white!

The only way to capture these colours, especially as the climax or finale of the show reaches a crescendo, is to set your aperture at f/22 and shoot for 1 second or LESS. The fireworks at this point are overlapping and your very sensitive sensor, is recording this by combining all the colours to give you... white.

Finally, achieving good photos takes practice and patience. Don't go to a show with the intent of taking 200 photos, because you will end up with probably one lucky shot, and 199 poor or average shots.  Less is more!

Watch the show, and pay attention to how bright the light is. This is crucial!  If the explosions are bright, close down... if weak... open up. One hand on the camera controlling your aperture, the other hand on your remote control, opening and closing your shutter.

From experience, most of my successful images were taken between f/11 and f/22 for an average of 1 to 4 seconds each. During the show’s climax when perhaps hundreds of rockets are filling the sky, much shorter exposure times will be required, as short as a
1/4 second!

Don't forget to periodically review your images with the histogram to see how you’re doing.

If your camera has an RGB setting, display all three color channels to make sure you are not clipping and of the channels, especially the RED channel which usually clips first (by climbing “the wall” on the right side of the display).

Perhaps you will end up photographing only 60 or 70 images (an average of 2 or 3 per minute in a 30 minute show), however your chances of achieving say 10 or more really good images, or “keepers”... will be much better than if you had shot "hundreds."

Happy shooting!
