Since the marvelous Cezanne and Van Gogh, perspective has become a much more fluid concept than it once was. Now sometimes playing by the perspective rules is important; sometimes not so much.
It's more than okay when Cezanne's apples seem to spill right out of his painting because his table looks tilted. And Van Gogh's bedroom wouldn't appear nearly as inviting if its perspective was not skewed as though asking us to come in and take a nap.
Dufy playfully ignored most of the guidelines. The contemporary Dan McCaw tinkers so subtly in the interest of design that his rule bending can almost go unnoticed.
In Sidewalk Artist, I toyed with perspective, too. I wanted the viewer to see her chalk drawing because everyone in the painting is oblivious to both it and its artist.
