What is the effect of Relative Size in depth perception?

The concept of Relative Size in depth perception is grounded in how we perceive the size of objects in relation to one another and their distance from us. When we observe objects, those that are farther away will appear smaller than those that are closer, even if they are actually of the same size. This principle allows us to gauge the depth and distance of objects within our visual field, enabling us to discern spatial relationships.

For instance, when viewing a scene with several trees, the trees that are nearer will appear larger compared to those in the background, which we perceive as smaller due to their distance. This visual cue is critical to understanding the three-dimensional layout of our environment, making Relative Size a key factor that aids in depth perception. Thus, the statement that objects appear smaller as they are farther away accurately encapsulates the essence of how Relative Size influences what we see.
