01 What is the benefit of directing shading strokes according to the object’s form?
Answer and explanation
Correct answer: C. The object’s volume becomes clearer
Explanation: The governing concept is form-following mark-making. When strokes curve or travel in the same direction as the object’s surface, they describe its contour and help the viewer understand turning planes. This makes the object’s three-dimensional volume clearer, so option C is correct. Such strokes do not change paper size or pencil hardness, and they do not remove the shadow; instead, they help organise it convincingly.
