Thursday, July 27 through Sunday, July 30, a party of night photography enthusiasts from around the country explored Fort East Martello in Key West and Fort Jefferson at Dry Tortugas National Park via a “Dry Tortugas by Boat and Night Photography” workshop presented by Key West Art & Historical Society in partnership with Dry Tortugas National Park and led by visiting “National Parks at Night” expert photographers and educators Gabriel Biderman and Tim Cooper. Under a waxing crescent moon and a brilliant Milky Way, the photographers experimented with long exposures lasting from a few minutes to multiple hours; image stacking – which entails taking multiple shots of the same exact scene over a period of time, which are then stacked and merged in post-production to create a single image showing the passage of time; and light painting, an effect achieved by moving a hand-held light source to selectively illuminate parts of a scene during a long exposure.
