painting people

It is very difficult to paint people all evening after working with them all day. Somehow friends think because I look at people all day that painting human models will be easy. I wonder where they get that idea. Yes I took multiple anatomy and human physiology classes to earn a Master Degree in Science, however, painting people is quite a unique challenge. Once in the room and set up, I watch others set up, and wait for the model to arrive. As we chat about our weeks the fatique of the day lifts with the anticipation of the evenings session. Soon the creative energy in the room becomes contagious, and I can focus in on the model. Forgetting about the stress of the day, I try to interpret what I see while applying past lessons. How does that go again? Paint what you see, not what you know? Or was it vice versa? Proper perspective dictates that I firmly place the person on the chair, and the chair on the floor to keep her from falling over.........It may be more fun if she does.
