The first thing MacPherson wants you to do is to determine the lightest light. In my composition it is going to be a setting sun. I am careful not to use pure white..I'll use lemon yellow in white.
Then he says find the darkest dark. My painting/design is going to use a lot of dark..but the darkest dark is going to be in the building.
I am using the BIG brushes..like Kitty insists I do.
