Sculptural lighting

EN: Sculptural lighting

Fotografie

Modeling with lights to emphasize planes and Texture. Consider using the term to describe a subject/background relationship in which the bright edge of the subject (key side) stands out against a dark part of the background, and the shadow side of the subject separates from a light area of the background. The result is about as close as 2D can get to looking like 3D.
