Anamorphic Illusions



Julian Beever creates anamorphic illusions, his canvas is the street pavement. He paints everyday objects as if they had been discarded right there on the street. These street paintings when viewed from the intended angle take on a 3D appearance, but when viewed from any other position betray their true and flat form. Not everyone appreciates pavement art. On occasions, a painting has to be abandoned after a complaint from a member of the public, perhaps after a full day's work. The Real Thing

The science behind the illusion is explained in a paper entitled "Lightness Perception and Lightness Illusion" written by Edward H. Adelson of the Department of Brain and Cognitive Sciences at the Massachusetts Institute of Technology. Illusion
"Every light is a shade, compared to the higher lights, till you come to the sun; and every shade is a light, compared to the deeper shades, till you come to the night." John Ruskin, 1879.
