Shadows and modelling: revealing shape
Shadows are not always a fault. They can reveal form or conceal important detail.
Directional light produces stronger shadows and reveals surface texture. Light arriving from many directions softens shadows but can make three-dimensional forms less distinct. The useful balance depends on whether people are talking, assembling components or inspecting surfaces.
Workplace design needs to consider hands, tools and the worker’s own body. A bright calculated work plane offers little benefit if the task is shaded during use. Movable workstations and changing working positions therefore deserve particular attention.
Test sample lighting with the real task and representative materials. Balanced general illumination combined with carefully positioned task lighting can be useful. Additional luminaires should not introduce confusing multiple shadows or shine directly into the field of view. The objective is a clearly visible task, not a shadow-free photograph of an empty room.
What to clarify for your project
- Consider shadows from bodies and tools.
- Test material samples during the actual task.
- Avoid added glare and confusing multiple shadows.
Remember: Shape shadows deliberately and assess them during real work.
