Head lighting reference: one head under eight lights
These eight frames keep everything still except the light. The head is the hard-plane study head, turned 45 degrees to its left, so its ear faces you and the face turns toward the right of the page. The light circles the head at one height, 35 degrees up. Watch where the shadow edge lands on each plane: the brow, the cheekbone, the side of the nose and the corner of the jaw.
Eight light directions








Using the frames
Squint at a frame until the details disappear and only two or three values remain. Copy those shapes first, as flat areas, before you add any half tones. The frames with the light behind the head are the hardest to draw, because the form is described almost entirely by the shadow side.
The same head appears without lighting changes, at every angle of the turn, in the head rotation reference, and the construction is drawn step by step in how to draw the head at any angle, step by step.
Keep drawing
The full set is in head lighting reference, volume 1: four heads under ten light directions at sixteen turns, with sheets, turning loops and light sweep loops.
