ABSTRACT
This chapter discusses some physical aspects of light and perceptual findings. It analyzes that the way people understand mirror images is relevant and probably relates to choices artists make when creating compositions. The chapter considers possible roles for mirror neuron networks when viewers interpret pictures. The word "reflection" can mean bounces back like an image in a mirror. Mirrors have surfaces that reflect objects and people located opposite them accurately such as glass mirrors, water, and shiny metal. Light that people can see is a small portion of the electromagnetic energy that is present in our world; this energy is the result of electrons moving around in atoms in space. In brightness contrast, human visual system takes account of the luminance of surrounding areas in an image when perceiving the light intensities of a target. The more general knowledge people have about where shadows should be, the better one's can correct for differences in absolute light intensity in the picture.
