The film was shot by uniformly and deliberately underexposing the film stock. In the processing, the super-16mm black-and-white negative was "pushed" (a process which compensates for lack of proper exposure), thus heightening the grain. In addition to this, the blacks, whites and grays in the image appear precisely and properly distinguished from each other. This accounts for the unique visual quality and peculiar texture of the film. The contrast was also especially boosted for the film's rural exteriors, which were shot in West Grove, Pennsylvania, about three hours from the city of Philadelphia, where the majority of the film was shot. Some of the "home movie sequences" shot especially for the film were "pulled," which compensates for overexposure, to give it an opposing quality to the rest of the film, which is all "pushed" material.
