What is possibly the world’s largest photograph was created on Wednesday at the former El Toro US Marine Base in California. The non-profit Legacy Project used a hangar at the base to create the world’s largest camera obscura by opening a tiny hole in the hangar wall and letting in a beam of light to enter and fall on a huge sheet of light-sensitive fabric more than 30 yards wide and 3 stories tall. It took 35 minutes of exposure and 60 volunteers to develop the photo by moving the fabric through a 1-foot deep tray of developing solution.
So, why is this relevant to geography, you ask? Because the photo documented the landscape of the base before it is redeveloped for other uses, so it is also the world’s largest landscape photo.
