Monocular Cues
You can gauge the distance and depth in this photo with at least four types of monocular cues: (1) People that are farther away look smaller (relative size). (2) The two sides of the street start out parallel but converge as distance increases (linear perspective). (3) The trees in the front block those that are behind (interposition). (4) Textures are more apparent for closer objects (texture gradient).
