Drawing DRAWING BY ERASING
Drawing by Erasing Drawing by erasing involves 'drawing' the lightest areas of a pictures with an eraser (working in the reverse). You would begin by darkening your paper by adding layers of charcoal. Instead of using a pencil to build up layers of shading, use a kneaded eraser to gradually take away the highlights.
Drawing by Erasing The key is to take a little bit of charcoal away at a time. You would not just draw with your eraser. The goal is to work back and forth with your eraser and your charcoal to create the perfect values.
