Largest Camera Obscura ever

The worlds largest pinhole camera, or camera obscura, was contructed with a abandoned F-18 hanger. Artists used 1.5 MILES of black gorrilla tape and 40 gallons of black spray paint to make tha hanger light-tight. the goal was to make a black and white picture of the Marine Corps air station with the San Juaquin hills in the background.  A huge piece of muslin cloth was made light sensitive by coating it with 80 litres of gelatin silver hilade. The resulting finished print was nearly 108 ft (33 m) wide and 85 ft  high and was exhibited for the first time at the Art Center College of Design in Pasadena, California, on September 6, 2007. Quite a bit bigger than mine.
