Which depth cue provides information about the distance based on distance perception from light changes?

The depth cue that provides information about distance through changes in light is relative brightness. This cue relies on the perception that objects farther away from a light source appear dimmer than those closer to it. The brain interprets this variation in brightness, allowing us to make judgments about the spatial arrangement of objects in our surroundings.

Relative brightness helps us assess depth by taking into account factors such as light intensity and surface orientation. For instance, an object illuminated directly will be seen as brighter than the same object in shadow, leading to the conclusion that the illuminated one is in the foreground while the shadowed one may be farther away.

Other options like interposition and texture gradient also provide depth cues but do so through different sensory information. Interposition relates to how one object obscures another, indicating proximity, while texture gradient involves the perception of detail in surfaces as they recede into the distance. However, neither of these specifically focuses on how changes in light intensity affect depth perception the way relative brightness does. Thus, relative brightness is the most appropriate choice for this question.
