How Do You See It?

“When we “see” things, we see by means of light. Select any object such as a book cover, table top, or a flat sheet of pink paper. Look at any single point or uniform area of the object. Now let your eye wander across the whole object. Notice how the aspects of lights you see vary over the surface from one place to another. Note also how your brain interprets that variation. Through such evaluations of patterns of light distribution made over and over again during the course of each day we make most of our judgments concerning things we see. Patterns of light entering the eye are the stimuli on which appearance judgments are based.”

-Richard S Hunter and Richard W. Harold, The Measurement of Appearance
