Subtractive Charcoal Drawing is a method of drawing usually completed with charcoal. A layer of charcoal was evenly spread and rubbed by the students hands on a sheet of paper. Using an eraser as the drawing tool, the drawing appears by slowly removing the charcoal with a kneaded eraser. The students started by erasing away the brightest values of the objects and gradually decreased the pressure of the eraser to create the middle values or added more charcoal to create the dark values of the drawing.
