"Edges" (excerpt)
Edges are an aesthetic problem artists encounter on the journey called “learning to paint”. With the corollary, “focus”, edges are part of a most intriguing study that can add seemingly magical qualities to a painting. Form, value control, and composition are three essential areas that come under the discipline of edges. The use of edges and focus convey the illusion of form. They are also necessary to express the tactile qualities of the subject matter, and in composition, flow and structure are limned by the use of open and closed edges. The abstract of the composition can be defined as a sequence of open and closed edges. Lastly, and perhaps one of the subtlest usages of edges, is that of being able to change the “look” of a value without actually changing the value.
