Which finish is characterized by a dull, non-gloss surface?

• A. Direct Lighting
• B. Dome
• C. Flat Finish
• D. Fiberglass

Answer: (C)

Light behavior on surfaces is the key here. A dull, non-gloss surface reflects very little light and has no shiny highlight, which is the hallmark of a flat finish. In restorative art, a flat (matte) finish gives a natural, non-reflective appearance and helps prevent glare in photography or display. The other terms relate to lighting or materials rather than the surface texture: direct lighting and dome describe how light is positioned or diffused, not the finish itself; fiberglass is a material, not a surface finish. So the dull, non-gloss look correctly corresponds to a flat finish.
