Now that is big

This is the largest photograph ever produced in one sheet. The Legacy Project turned an aircraft carrier in to a camera obscura and hand applied the emulsion to a custom made canvas to create it. The specs on what it took to make this image are mind boggling.

The Legacy Project to Exhibit the World’s Largest Photograph -Photo Reporter

The world’s largest photograph, the Great Picture, which is 3,375 square feet, premiers at Pasadena’s Art Center College of Design at the South Campus Wind Tunnel Gallery in a showing that will be held September 6–29, 2007.

Only a handful of museums are large enough to display the photograph, which is a history-making gelatin silver image 3 stories high by 11 stories wide. The photograph was created over nine months in 2006 by six well-known photographic artists collectively known as The Legacy Project and 400 volunteers, artists and experts. The $65,000 photograph was made using a shuttered Southern California F-18 jet aircraft hangar transformed into a gigantic camera obscura. The largest camera ever made, it measures 44' 2" high by 79' 6" deep by 161' 6" wide. To darken the hanger, 24,000 square feet of 6 mil black viscuine, 1,300 gallons of foam gap filler, 1.52 miles of black gorilla tape and 40 cans of black spray paint were needed. The aperture was a one-quarter inch (6mm) pinhole 15 feet above ground level, with no lens or other optics used.

Working in their jet hangar/camera, the group hand-applied 80 liters of gelatin silver halide emulsion to a seamless 107' 5" by 31' 5" canvas substrate custom made in Germany. Development was done in an Olympic-pool-size developing tray using 10 submersible pumps and 1,800 gallons of black-and-white chemistry.

The Guinness Book of Records preapproved and is now evaluating applications in two categories: world’s largest photograph and camera.
