Lighting illuminates, sure. But that’s not all. It can suggest shape and dimension, draw attention to specific subject details or qualities, freeze action, or separate your subject from the background. In this amazing image by Scott Markewitz, it does all of these things. Markewitz, based in Salt Lake City, UT, and Provence, France, is a ski, action, and adventure specialist. He was hired by helmet maker Giro to photograph professional mountain biker Paul Basagoitia doing a “Superman Seat Grab,” as the trick is called.
