Maximize Emotional Impact : UPPER Face "Hot Spots"
 | Brains are efficient – they pay particular attention to the parts of our environment that will give us the most information for the least work. When it comes to assessing the degree of illumination on a surface divided into shadow and light, for example, we focus on the boundary where there is the most rapid change from one to the other. Tonal changes that occur elsewhere on the surface don’t register nearly as strongly, allowing artists to use the shadow edge to either intensify, or diminish, the amount of perceived contrast and brightness. |
