Which lighting displays a silhouette between the light source and the building?

• A. Backlighting
• B. Flood lighting
• C. Spotlighting
• D. Surface lighting

Answer: (D)

Silhouettes appear when a bright, directional light shines on a surface and objects between the light and that surface block part of the beam, creating a dark outline. With surface lighting, the fixture sits on or just in front of a surface and illuminates toward the building. Any object that lies between that light and the building will cast a shadow onto the building, producing a clear silhouette of that object against the lit facade. This setup emphasizes the shape of the intervening form, which is exactly what the question describes.

Backlighting would place the light behind the subject relative to the viewer, giving a silhouette against a bright background rather than on the building surface. Flood lighting is broad and uniform, which reduces distinct silhouettes. Spotlighting sends a focused beam to a specific spot rather than creating a silhouette on a building surface. Surface lighting specifically aligns with creating silhouettes on the building by objects intercepting light from a surface, so it’s the best fit.
