Our little town's annual festival ends with fireworks. Last year we had grandstand seats from our own balcony. This year the fireworks were moved to a new site and when the display began I had to move too! I briskly carried my tripod-mounted camera up the hill about a quarter-mile until I spied a parking area with a clear view of the air bursts. I greeted the people standing there, plunked down my tripod, and started shooting with the EOS 50D. I got many pleasing shots of the aerial display but this — oooh! ahhh! — is among my favorites. Looks a bit like subatomic particle collisions. Nice end to my weekend even if I didn't go to the festival and get cotton candy as I'd hoped. For those who may be wondering: 200mm lens, ISO 100, 3 sec., f/11.
