illusion of depth

The illusion of depth refers to visual tricks that make a flat image appear three-dimensional, giving the sense of distance and space. Our brain interprets clues like shading, perspective, size differences, and how objects overlap to perceive depth. Artists and photographers often use these cues intentionally to create realistic images. This process allows us to see a two-dimensional picture as having depth and dimension, even though the image itself is flat. The illusion works because our visual system is wired to interpret certain patterns as indicating spatial relationships, enriching our perception of reality.
