Six Photographers from the Legacy Project have developed the ‘world’s largest photo’ with the help of a photography technique called Camera obscura. The photographers used the world’s largest camera to take this 28 x 108 feet b&w photo in a converted airplane hangar. The cloth was exposed for 35 minutes. The photographers and 60 volunteers developed the image by moving the fabric into an enormous, 1-foot-deep tray. The unique project has been qualified for the two categories in the Guinness Book of World Records, the world’s largest photograph and the world’s largest camera.
