CAMERA TRUCK
2009-04-13Camera truck is the worlds largest travelling camera, it takes pictures about 3000 times larger than 35mm negative. The camera truck works in exactly the same way as a pinhole camera. Light enters a sealed chamber through a tiny opening, and falls onto the opposite wall inside. Here it produces an inverted image of the world outside.
The first pinhole photograph was taken by Scottish scientist Sir David Brewster but the pinhole effect was observed by the Chinese philospher Mo Ti in 5 BC and also Aristotle in 4 BC. The cameratruck uses this same principle only amplified thousands of times and with a lens added for sharper detail in the final shots. The cargo box of the truck becomes a sealed chamber, and the aperture is a small hole in one side. As light enters the truck, it falls onto giant sheets of photographic paper pinned to the opposite wall. This is how Camera truck creates giant negatives, almost three metres wide.
