Nolan built only one set for the film, an "under-the-stage section that houses the machinery that makes the larger illusions work," preferring to simply dress various Los Angeles locations and sound stages to stand in for Colorado and Victorian England. In contrast to most period pieces, Nolan kept up the quick pace of production by shooting with handheld cameras, and refrained from using artificial lighting in some scenes, relying instead on natural light on location. Costume designer Joan Bergin chose attractive, modern Victorian fashions for Scarlett Johansson; cinematographer Wally Pfister captured the mood with soft earth tones as white and black colors provided background contrasts, bringing actors' faces to the foreground.
