Rick Graves can stop time. OK, not really, but he can freeze 43 NASCAR racers clocking almost 200 mph. How? The pro shooter modified his Hasselblad into what he calls a DistaCam — adding a high-velocity motor, locking the shutter open, and inserting a metal plate with a laser-cut slit. Whenever Graves triggers the motor, film zips past the slit at up to 1,400 rpm, capturing stills of the speeding cars. "Failure is a necessity," he says, "and a lot of times, success is luck."
