We went to First Night in Boston again this year and watched the 7pm family fireworks. I had one roll of CineStill 800Tungsten film in my camera (Leica M3 with 50mm Summicron lens). This is Kodak movie film with the black "rem-jet" layer removed, so it can be developed using the C-41 process like any other color negative film. But as a side effect, this film has no anti-halation layer. That can create a bright red halo when there is a point light source in the picture. When photographing the fireworks, I got plenty of that. It did create some rather surreal photos...
