UK-based photographer Edward Horsford specializes in high speed photography and one day decided to work with water balloons. His motivation? He is interested in “capturing a moment rarely seen and almost never captured.” He admits that “[his] camera is really the least important part of the shots.” So he uses a custom, Arduino-based flash trigger to produce specific lighting arrangements required to capture the water balloon at the precise point of explosion. The timing of the flash is key; the aforementioned trigger picks up the sound of the balloon popping and flashes at what it thinks to be the most opportune moment. Horsford must be a patient man. And what might be considered the most impressive feat here? He manages to do it all without any assistance; from setting up the trigger, to holding and popping the balloon, to taking the picture. Impressive stuff, huh? Look in the gallery below to find a few more of these high speed water balloon shots, and head over to Horsford’s Flickr page to view the entire collection.
