CHONGQING (CQNEWS) -- Mozi made the first successful experiment of pinhole imaging over 2,000 years ago, but he couldn’t thought that pinhole imaging is used in photography technology called pinhole photography. As a famous pinhole photographer, Shi Guorui started his pinhole photography in 1996, and has completed the huge works like Jinshanling Great Wall and Mount Qomolangma. Chaotianmen, the landmark of Chongqing, is his next target. He is planning to use pinhole photography to make more people know Chongqing.

When it comes to pinhole photography, many people may not know it well. In fact, the principle of pinhole photography is the same as pinhole imaging in physics. Put a board with a small hole between a photographic paper and an object, then an inverted image will be formed on the photographic paper. Remove the board forth and back, and the size of the image on the photographic paper will change accordingly. This also is the principle that light travels in straight lines. Shi Guorui started his pinhole photography in 1996 and has become a famous pinhole photographer.

In 2002, Shi Guorui utilized a beacon tower of the Great Wall as a camera obscura to photograph the Great Wall, which is his first outdoor large work by pinhole photography.
