Getting more than a few people (especially after the reception) to be still long enough for a long-exposure sparkler shot is not an easy task. We had a decent system to get everyone on the same page, get their sparklers lit, and their photographs taken without a hitch! Oh, and there was a bat, yes BAT sitting in the wall behind me and my tripod as I took this shot...no big deal, but the little bugger was distracting!
