Subtractive drawing is a technique in which the drawing surface is covered with graphite or charcoal marks and then erased to make the image.[1] This technique is often used to add texture, establish tonal shapes, or create the appearance of reflected light in a drawing.[2][3] Artists commonly use a kneaded or putty eraser for this type of drawing, due to its ability to absorb pigment and be manipulated into custom shapes, including fine tips.[1][2][4] Charcoal figure drawing commonly uses a combination of subtractive and additive drawing techniques.[3]
