Shooting Technique – Flash + Fireworks

Article by Neil van Niekerk

Photographing people with fireworks in the background, is just an application of the technique known as dragging the shutter.

I had the couple in an area where there wasn’t much ambient light, so that I could light them mostly with flash. The strobe was a Quantum T2 with an umbrella.

My flash exposure was determined in that I wanted the couple correctly exposed .. but my actual settings were dictated by my choices made in how I wanted the fireworks to register.

For my fireworks exposure, I had to juggle the three controls again :
shutter speed / aperture / iso.

That particular photograph was 1 sec @ f6.7 @ 400 iso

You don’t necessarily want a high iso .. because you want your shutter speed to be slow. Slow enough to record the fireworks as streaks of light. There is a lot of leeway here .. and chimping will tell you whether you need to adjust your settings. Therefore your is range should be 100 to 400 iso. Then your shutter speed should be 1 second or slower. In other words, you need a tripod.

Recording multiple bursts of fireworks by blanking out the frame with a black card is a great idea. This photograph was a single exposure though.

By chimping other firework bursts, I found that f6.7 @ 400 iso @ 1 sec gave me enough firework trails and the fireworks itself weren’t over-exposed in the shot.

So using f6.7 @ 400 iso, I set my Quantum T2 to an appropriate power level, to give me that exposure. (Manual flash in this instance, since my subject was in a specific position in relation to my strobe.)

f4.5 @ 200 iso @ 2 seconds .. would’ve given me exactly the same exposure, but the firework trails would’ve been longer. There is a lot of leeway here, and you shouldn’t be bound by specific settings. But my suggestion would be to start at 1 second (or slower) and 400 or 20O iso … and chimp to taste. Rear-curtain sync would not have had any effect here, since the couple was static in the frame.

    Thank you for the article. I am also a photographer. Yet I can say that much depends on the same fireworks. I was on one’s birthday, it is even asked where he got such beautiful fireworks..
