Atmospheric perspective
noun phrase · colour / depth perception
The three effects
Distance changes three things about a depicted object: hue shifts cooler (toward blue), chroma reduces (toward neutral grey), value contrast compresses (darks lighten, lights darken). A correctly painted landscape shows the highest chroma and the strongest value contrast in the foreground, with both progressively reduced toward the background.
Historical description
Leonardo da Vinci described atmospheric perspective in his notebooks (MS A and BN 2038) in the late fifteenth century. The seventeenth-century Dutch landscape painters — Ruisdael, Cuyp, van Goyen — made it the workhorse depth cue for any landscape with more than a few hundred metres of recession. The physical mechanism (Rayleigh scattering) was characterised in the nineteenth century but matches what painters had observed empirically for four hundred years.
Common misuse
Beginners often paint distant mountains in foreground saturation, losing the depth reading. Correct atmospheric perspective requires reducing chroma by 50 percent or more for elements at the horizon line.
