How can background tone affect the lit edge of an object?

Answer and explanation

Correct answer: A dark background can make a light edge clearer

The governing concept is value contrast. An object’s edge is judged in relation to the tone immediately around it, not in isolation. If a light edge is placed against a darker background, the difference in value increases and the edge becomes easier to see. Therefore option A is correct. The background does affect edge perception; it does not automatically blacken every edge or influence only the cast shadow.
