Sometimes technique is as interesting as the photo. This was shot with a Canon 5D Mark III and a 14mm f/2.8 Canon lens. The extreme width of the lens is deceptive — I’m only about four feet from the man. I’m also shooting blind with the camera held sideways at my waist. Between that and the camera’s quiet shutter, I went unnoticed; however, considering the fascination of mobile email, it’s possible I might have gone unnoticed with a tripod and lighting assistant.
