Yesterday I set up an old milk can on the floor in the middle of my drawing classroom at Sacramento City College and had my students spend several hours rendering the can in fabulous vine charcoal. I did this demo to give them the idea that charcoal is both an additive and SUBTRACTIVE medium. After drawing the contours of the milk can very lightly in charcoal, I then proceeded to cover the entire contour drawing in mid range grey charcoal. I then PULLED OFF charcoal with a kneaded eraser and pencil eraser (for small highlight areas) to render the lighter areas on the can (both reflective light and local lighter values of the can). Charcoal was then ADDED to render the darker areas of the can (shadow and local values). ADD + SUBTRACT+ ADD. Whenever you succeed in rendering a successful charcoal drawing, celebrate with a nice cold glass of milk! Milk can help keep your muscles and bones healthy and therefore aid in your drawing ability. Cheers!
