01 What is the most direct change in value contrast when the light source is changed?
Answer and explanation
Correct answer: B. The position and intensity of light and shadow will change
Explanation: The governing concept is value contrast, the difference between lighter and darker areas. Changing the light source changes the direction from which illumination arrives, so highlights and cast or form shadows shift position and may become stronger or weaker. Hence B is correct. The colour wheel, physical size, and existence of surface texture do not automatically change merely because the lighting direction changes.
