Thanks for the clarification. Light needs shadows to be light. However, I think 'eyes are attracted by contrast' makes more sense than my initial statement. Photographers would be well advised to communicate with other graphical artists more than they do. The studies of Alfred Yarbus from 1967 show that the viewer's screening of portraits is different from looking at other pictures. In portraits, eyes and noses are specially selected. Regards Ralph W.
