By Craig Nelson. A reference photo of a dancer allows Craig Nelson to emphasize gesture in a charcoal drawing and capture an exciting pose not possible with a live model. Craig eases into the drawing by translating lines from his photo to his paper. He concentrates on angles and uses an imaginary grid and plumb lines to render a ghost drawing of his subject. You’ll have continual access to Craig's reference photo as he works, allowing you to follow his interpretation of gesture. Craig adds facial features and shadows early in the process but plans for later changes.
