Getting ready for Plein Air Sunday
I did this quick demo in preparation for out next Sunday painting session. We talked about the principles of atmospheric perspective. The first rule is that contrast in value diminishes as things recede in the distance. So here I just painted three palm trees that are lighter as they go back against the white background. Just the change in value makes it seem like the tree on the right is in back of the other two.
Another technique with trees is to pay attention to the negative space and a good technique is to paint the positive space like I did above, then come in and paint the trees again by looking at the negative space. This breaks up the tendency to do cartoon or repetitive trees from your head rather than from observation. SOmetimes you have to go back and forth from positive to negative to ge a tree that captures the actual gesture of what you are looking at.
