A former aircraft hanger in California has been turned into a giant pinhole camera in a bid to create the world?s largest photograph on a single sensitised surface.

Once used by the US Marine Corps to house fighter jets, the hanger ? now claimed to be the world?s largest camera – is a camera obscura that uses a hole in one side to project a massive panoramic image on a sheet of light-sensitive fabric.

The fabric is said to measure 31x111ft and is covered in 20 gallons of light-sensitive emulsion.

The exposure process is expected to take up to ten days and be completed by 8 July, according to the six photographers behind the scheme, which is called The Legacy Project.

They will use 200 gallons of b&w developer and 600 gallons of fixer in a giant tub to produce the image, dubbed The Great Picture.

Guinness World Records is reported to have created two new categories for the project ? world?s largest camera and world?s largest photograph.

Afterwards the decommissioned airbase – which is located in Irvine, California – will be turned into a park, sports complex and residential area.

A limited-edition print ? a composite image showing a negative and positive version of the photograph ? will be on sale. However, there will only be 20 of the 30inx50in prints made available and their price will shoot up from $1,600 to $2,600 for orders placed after 4 July.
