Six photographer artists, Jerry Burchfield, Mark Chamberlain, Jacques Garnier, Rob Johnson, Douglas McCulloh, and Clayton Spada plus approximately 400 assistants built the world's largest pinhole camera in building #115 at El Toro using 24,000 square feet (2,200 m2) six mil black visqueen, 1,300 US gallons (4,900 l) of foam gap filler, 1.5 miles (2.4 km) of 2-inch (5.1 cm) wide black Gorilla Tape and 40 US gallons (150 l) of black spray paint to make the hangar light-tight. The camera measured 160 ft (48.76 m) wide x 45 ft (13.71 m) high x 80 ft (24.38 m) deep.[1]

A seamless piece of muslin cloth was made light sensitive by coating it with 21 US gallons (80 l) of gelatin silver halide emulsion and then hung from the ceiling at a distance of about 80 feet (24 m) from a pinhole, just under 6 millimetres (0.24 in) in diameter and situated 15 feet (4.6 m) above ground level on the hangar's metal door. The distance between the pinhole and the cloth was determined to be 55 feet (17 m) for best coverage, and the exposure time was calculated at 35 minutes.
