At a high pace slides, each consisting nothing more then a small dot, are shown. By pace and the intensity of the light, the after-image is mixed with those of the next slides. An afterimage or ghost image or image burn-in is an optical illusion that refers to an image continuing to appear in one’s vision after the exposure to the original image has ceased.
