01 Which option shows contrast created by the direction of light?
Answer and explanation
Correct answer: C. A face lit from one side with deep shadow on the other
Explanation: The governing concept is light-and-dark contrast produced by directional illumination. When light strikes a face from one side, that side becomes brighter while the opposite side receives less light and forms a deep shadow. The difference in value models the direction of the light source and gives the face depth, so option C is correct. Equal lighting, no shadows, or equal values would reduce rather than create this contrast.
