Maybe stretching the theme a little, but this was taken hand-held very much "on the fly". The organizers started the display without much notice so I didn't have time to set up a tripod. The bursts were going off right over our heads, so I just kept panning with the fireworks as they were leaving the ground (like a trap shooter), and firing an instant before I thought the burst was about to happen. I did get a few keepers (though a little shaky).
