Camera notes: These were taken at the show in Leesburg, Virginia. I'm pleased with how they came out. My only complaint is that I didn't bring a sturdier tripod. The best ones came out using my wide angle Sigma zoom lens in manual mode with f/8, ISO 100, 4 second aperture, focused manually to infinity. I experimented going as low as 2 seconds on f/8, and as far as 6 second aperture on f/16, thereby putting less or more fireworks into the frame.
