Photojournalists often will move kinetically through a scene. Like a postmodern dancer interpreting society’s hunger for visual stimuli, they’ll get close to their subjects, then quickly move far away, take a vertical for the magazine cover, then back to horizontals, leap down to get a low shot, climb to a high shot, a detail, a portrait, a left-facing action shot, then right. To make a picture essay have rhythm and flow, it needs variety.
