Here he describes the techniques he uses, such as shaping the pencil end to make the right mark, building up a pattern of lights and darks, sketching in pencil or ballpoint pen, measuring angles and proportions, impressing grooves and lifting out tone with a putty eraser. Four demonstrations show how to use these techniques to create tree drawings, from a detailed study of oak leaves to a huge sequoia."@en . . "Trees in art." . . "Trees in art" . . . "træer" . .
