Oil on Canvas Work : 24" x 30"Frame 3.25" wide. The transitional period of dusk, dawn, before and after a storm, and even those grayed out days in winter when the sun’s light is most effusive, these are the qualities of light that I am most interested in. My goal is to have the painting emanate light, rather than just be a surface that records the reflection of light. This is why the shadow areas are important, for it is form that this emanation precedes. The light areas are focal points of this effort, but the power comes from the shadows.
