Here's a pre-4th of July sample of fireworks photos. The city of Littleton (South of Denver) had a town 'Block Party' with the old downtown Main street closed off, earlier this month. Several bands playing, street buskers, food vendors and lots of attractions for grown-ups and kids.
And TWO firework displays, 8:45 and 9:45 pm.
I went early and found out the display would be launched from the West end of Main street, which meant I'd be shooting over and around the trees that line the street. Next year I'll try to find a more open view, but I did manage to get part of the street activity (blurred by the slow shutter speed) in the wider shots.
Because of the tight viewing angle, a short zoom seemed like a good choice, although I normally use primes when I can.
Here's a few samples, all taken with the DA 16-45mm. This lens worked out perfectly, the wide end for the street view and 40-45mm was just long enough for the firework display. All shot with a K-7, aperture priority with -7/10 compensation, all f/8.0, shutter speeds about 4-5 seconds at ISO 200, 1.5 to 2.5 seconds at ISO 400. Tripod, cable release. I pre-focused the lens to infinity, then switched the setting to manual focus, so no 'hunting'.
