Learning this “trick of the artist” involves imaging: as you are drawing, you will occasionally squint your eyes to see if you can yet “see” the form you intend. And when you “see” it—that is, when the clues are sufficient to trigger the envisioned image—stop! So many times in workshops, watching a student draw lights and shadows, I find myself urgently saying, “Stop! It’s there. You’ve got it!”
