This was tricky. I had the camera in shutter speed priority until the fireworks started and then switched to manual mode to get a reasonable exposure. This is 1071 frames shot 6 second apart for 107 minutes or 1 hour and 47 minutes. It is played back at 15 fps so it isn't all flashes and the boats don't look crazy fast. I wanted to take more photos after so you could see the rush of boats come back but a little girl needed to go pee.
