Summer balloon glow in Forest Park of St Louis (site of 1904 World's Fair). I have two shots--one in which the balloons overlap with one another while glowing simultaneously, and this one where I wanted the underside of a balloon but wanted the other balloons in the shot too. It was difficult to balance the image compositionally while keeping the balloons from interfering with one another, and waiting for the split second that the burners went off together. Some pilots were on cue, others not so much.

lens: Tokina 11-18 mm, 11 mm, f/2.8, 1/500 s, ISO 800
