When we interpret these shapes, we assume that the illuminant is elevated. This assumption about the position of the illuminant guides our inference about the shape of objects in the image. The distinction between mound and crater in these images is mediated mainly by the shading differences. Hence, rotating the images changes the shading relationship and we reinterpret the shape. Ramachandran (1988; see also Knill and Kersten, 1991) has demonstrated this phenomenon in a number of different ways. He argues further that the brain simplifies the interpretation of images by assuming the illumination consists of a single light source.<\/p><\/blockquote>\n<p>I found another demonstration of the principle <a title=\"Mighty Optical Illusions: 'Moon Boot Switcheroo Illusion'\" href=\"http:\/\/www.moillusions.com\/2009\/10\/moon-boot-switcheroo-illusion.html\" target=\"_blank\">here<\/a>, using the famous photograph of Buzz Aldrin&#8217;s footprint on the surface of the moon.
