Fireworks Fiasco

Ski Side Fireworks 7D

Well, almost, anyway.  I wanted to photograph the neighborhood fireworks display and play with a handful of cameras in the process.  Here’s what I did:

G3 using the built-in intervalometer at 1 shot per minute for 100 shots.  ISO 50, 2 second exposure, f4, manual focus at infinity.

G6 set up the same as the G3 but pointed in a different direction.

The G9 doesn’t have an intervalometer and no external connections to use one so the G9 was set in its “HD” movie mode (1024x768 at 15 fps).

G12 connected to a cheap no-name external intervalometer (worked fine).  ISO 80, 2 second exposure, f4, 1 shot every 4 seconds, manual focus at infinity.

7D triggered manually using wired remote, ISO 400, 2 seconds at f8. 

I knew I was trusting to luck on the G3 and G6 but it never occurred to me that my luck would be so bad.  Nothing.

The G9 movies were pretty bad and had lots of noise. 

Of the 298 G12 shots, a handful were OK.  That is, when the intervalometer got lucky, the photo was OK. 

I got by far the most keepers by triggering the 7D myself.  I used the old tried and true method of watching for a rocket launch and pressing the remote button – or just taking a random guess that it was about time for another launch.

The picture above is a composite of five shots that were combined in Photoshop.  Not bad but not what I hoped for.

Rockets' Red Glare


As we celebrate the "rockets' red glare, the bombs bursting in air", the flash from fully automatic cameras in the crowd can rival the glow of the fireworks. This is the time to turn off the flash and put the camera in some sort of manual mode -- preferably full manual mode: shutter speed, aperture and focus. This particular shot was taken at 1.3 seconds exposure, f5.6 and infinity focus. The camera was on a tripod.

The general idea is that the streaks of light from the fireworks are so quick and so bright that proper exposure is essentially set by only the ISO sensitivity and the aperture. The long exposure (usually about 1/2 to 2 seconds) is necessary to catch the streak of the rocket as well as the burst.

I've put a few more fireworks photos on my website at http://hornerbuck.com/GBfireworks.aspx
