From PetaPixel.com: "Dancers are often photographed with off-camera flashes and powder in order to capture their movement. Photographer Ben Franke recently completed a project titled Parkour Motion in which he used the same concept, except for parkour practitioners (called “traceurs”) rather than dancers. Here’s what Franke tells us about the project: I have been shooting the parkour scene in New York for the past few years. It’s a challenge for any photographer to convey authentic movement in a photograph — as it’s a 2D medium — but my series “Parkour Motion” attempts to translate motion by displaying the energy and power of these athletes. The photos were shot over two days in Manhattan with a Canon 5D Mark II and a 24-70mm lens. They were lit using a 580EX flash with an umbrella and a reflector for a bit of fill. The trails were created using flour."
