Dome lighting is an illumination device that illuminates objects with indirect light from various directions. Unlike ring lighting, which can cause irregularities, reflections, and halation on uneven objects such as convex and concave surfaces, dome lighting can provide soft indirect light.
– It can emphasize points you want to detect while maintaining uniformity on the surface.
– It also helps in reducing halation effects by averaging the brightness of the surface rather than eliminating halation itself.
