World's Largest Photograph

The image, which was developed July 8, 2006, will have its premier exhibition September 6 through 29, 2007 at the Art Center College of Design in Pasadena, California.

Imagine a photograph so big, its creators have trouble thinking of places large enough to display it. Imagine three stories high by eleven stories wide. Imagine a 1200 pound picture.
A group of six photographers known as "The Legacy Project," along with 400+ volunteers, artists and experts, have created the world's largest photograph, titled The Great Picture. The image, which was developed July 8, 2006, will have its premier exhibition September 6 through 29, 2007 at the Art Center College of Design in Pasadena, California.
Photographers Jerry Burchfield, Mark Chamberlain, Jacques Garnier, Rob Johnson, Douglas McCulloh, and Clayton Spada turned an F-18 jet aircraft hanger into a huge camera obscura, using 24,000 square feet of black plastic, 1300 gallons of foam gap filler, 1.52 miles of black tape and 40 cans of black spray paint to light proof the hangar.
To process the seamless muslin, special ordered from Germany, that they hand treated with 80 liters of gelatin silver halide emulsion, they constructed a gigantic tray made of the type of plastic used to line swimming pools. Developing took 5 hours to coordinate and 1800 gallons of black and white chemistry. "It was something like a cross between Ansel Adams' darkroom and Dante's Inferno," said Burchfield.
