‘Modelling sculptures with light and shadow’

Defining shapes with shadows

Directed light, produced by spotlights, creates hard-edged shadows for distinctive modelling of three-dimensional objects.

The position of the light source is crucial for the shadow image. A steep angle of incidence over a short distance produces long and large shadows.

Generally, an angle of incidence of 30° has proven optimal for the modelling of sculptures. Exhibition lighting based solely on directed light further enables sharp contrasts of light and dark. The localised beams of the Accent light evoke a magical atmosphere in which individual aspects can mysteriously stand out against the dark.

Luminaire arrangement for large objects

Large exhibits require multiple luminaires, each with narrow beams of light, to prevent glare for the observer.

Diffuse and directed light

Diffuse light comes from flat light sources such as luminous ceilings. Similar to an overcast sky, light is emitted uniformly from various directions producing virtually no shadows and leaving a flat impression of the sculpture.

Directed light, such as natural sunlight or accentuating spotlights, delivers the alternative of high-contrast shadows that give a dramatic effect, even to subtle contours.

Producing brilliance

Brilliance is useful in drawing attention to specific parts of an exhibition, as the highlights produced on the surfaces appear to wander when changing position in the room.

The arrangement of these highlights also sheds light on the shape of edges and forms of the exhibits. Objects are enhanced by emphasising their shape and texture through brilliance effects.
