The Conference National Board (NBE) – Restorative Art Section Practice Test

Direct lighting is illumination that shines straight onto the object, creating more defined highlights and shadows because the light travels directly from the source to the surface without much diffusion. This sharp illumination makes contours and texture easier to see, which is important when evaluating form in restorative art.

The other terms don’t describe how light interacts with a surface: fiberglass is a material, a flat finish is a type of surface coating, and a double seal is a sealing process.
