Aerial perspective
THE OPTICAL EFFECT ON THE VISIBILITY OF OBJECTS SEEN THROUGH AIR WITH DISTANCE
Atmospheric perspective; Aerial Perspective
Aerial perspective, or atmospheric perspective, refers to the effect the atmosphere has on the appearance of an object as viewed from a distance. As the distance between an object and a viewer increases, the contrast between the object and its background decreases, and the contrast of any markings or details within the object also decreases.
