Shadowed regions

Shadowed regions are areas where direct light from a source is blocked by an object, creating a darker zone behind it. These zones lack illumination because the object prevents light from reaching them directly. Shadows help us perceive the shape and position of objects more clearly. Their size and shape depend on the light source's position, the object’s shape, and the distance between them. Understanding shadows is essential in fields like art, photography, and science, as they provide visual cues about depth, spatial relationships, and the environment’s lighting conditions.
