Waiting on the fireworks, and I’m sure I looked like a total nerd dragging my family along on to a golf course hill behind our house with my tripod. Don’t care. Totally worth it! Longer exposures must make for bluer skies. It definitely makes a shot with more fireworks in one frame!I’m guessing the color of the firework has an effect on sky color, as well. Maybe?I never get tired of this!!!
