Today our model was unable to come to drawing class, so our instructor sat for us. Bob gave us some handouts on the planes of the face and talked about the structure and how the light affects the planes. Then we spent a few hours drawing. In the final 30 minutes Bob demonstrated how he would approach the drawing, using one of our fellow students as model, by first shading in the planes of the face. Then with just a few magic strokes of his kneaded eraser, he suggested the features. It was like magic to watch him coax the face out of the paper. Something to work at next time.
