With 2 painting session per day, the student's paintings improved. By Friday, they were really beginning to understand atmospheric perspective, and they were starting to "pitch" and simplify by "massing" their big value shapes.
One of the rainy days, we painted under the shelter of a big gazebo, and on the other days, we painted at various locations around Cambridge and Jeffersonville. With a small class, Jack and I got to paint, too. We went around and helped each student individually, but we also had students follow us around to observe the other crits. Watching us re-mass, explaining, as well as showing, "why" and "how" certain colors work to bring a sense of atmosphere and depth to a painting, really acelerated learning.
