Someone asked me just yesterday, after having read some entries here, whether I always started off with a black background. I answered him short of a full explanation (it was late) by saying, "No". Of the last four Redwood paintings, three did, and one started with white. In this entry and the next few, I'm going to show three examples where I didn't start with black and explain why. The first of these examples is that fourth Redwood.
In this case I began with white latex acrylic and defined the tree trunks in black acrylic. It was easier in this way because of the geometry of the tree trunks perspective.
