When you open your eyes in bright daylight, you become visually aware of the scene in front of you. That is to say, generically, for you might be blind, hallucinate, and so forth. To many people visual awareness appears three-fold extended in space, and evolving over time. One makes out objects and processes in intricate interrelations. Here we are mainly interested in immediate visual awareness of the type that happens when you look at a painting. We assume you close one eye and hold your position with respect to the canvas. This restriction cuts down on the complexity, for instance, it plays down the importance of visuomotor factors, binocular multiperspective, and scene changes.
