Distant Light

Distant light refers to illumination originating from sources that are so far away that their rays appear nearly parallel when they reach us. Examples include sunlight and distant stars. Because these sources are extremely far, the light they emit covers a broad area with minimal divergence, making the direction of the light consistent over large distances. In optics and photography, understanding distant light helps in controlling illumination and shadow effects, ensuring accurate lighting conditions. Essentially, distant light behaves as if it comes from infinitely far away, allowing us to model and work with it in various scientific and technical applications.
