For start I picked "Simple Value Plans" lesson, because I read a lot about how critical it is for a successful painting.
I watched the DVD and questions started popping up. Peggy decides to do a four value plan in her fist demo, but does not say why. Inside the disk "jacket" you can see examples of her value plans and notice that some are painted in just 3 values, while others are in 4. I wish Peggy explored this theme in the lession.
When I was doing the assignment, I noticed that sometimes you want to change the values of the background to improve design or get an effect you are after.
