York Dispatch - Ex-Marine base sets stage for world's largest photographSay "CHEESE-FACTORY" ...... :)
From the Article:
"The photographers are using a nearly 33-by-111 foot piece of white fabric covered in 20 gallons of light-sensitive emulsion as the photographic "negative."
After exposing the fabric for up to 10 days, they will develop it in a huge tub made of pool siding, using 200 gallons of black-and-white developer solution and 600 gallons of fixer."
