American photographer Gregory Crewdson can take months, years, to find the moment he's looking for. "The pictures are about creating a world," says Crewdson in the acclaimed documentary Gregory Crewdson: Brief Encounters. "I've always had images inside my head that I feel like I want to get out in the world." Crewdson starts his projects by location scouting, driving the streets of small-town Massachusetts, often visiting the same spots again and again. At this stage he doesn’t take a camera. Instead, he wants to get a real sense of the place – uninhibited by the lens. Once a location is set, he takes photos on his phone and works with his team to write a ‘description’ for each scene. From here on he operates like a film director. Lights, actors, wardrobe, art direction, props, cars. Crewdson takes all of his pictures at twilight, when the artificial lights of suburbia and fading light of the day work together in harmony. Eventually, the moment comes. For a split second, everything is calm, still and perfect.
