Bill Wadman is an American portrait photographer based in Brooklyn who is known for his photos capturing movement through long exposures of dancers in motion. The document describes one of Wadman's photos showing 9 dancers in varying positions from a 20 second exposure. It also discusses how the author emulated Wadman's style in their own photo by using a slow shutter speed and post-processing in Photoshop to darken the background and enhance the movement blurs and varying contrast levels created by the red clothing.
