Students in the T/TH class began portrait studies. As an introduction to the "proportions of the head", students made planar analysis drawings. A "planar" drawing flattens all curves into angles. Addressing the planes raises awareness of the subtle shifts of volume creating a stronger sense of structure. In addition, planes are important because they establish the placement for values. In Phoebe's drawing notice the angle of the hatching is directed by the planes, arcing downward across the cheeks and upward over the nose and forehead.
