William Richards used atmospheric perspective in this painting to create a illusion of space in his piece. The mountains in the back are less defined and lighter than the mountains which are closer up. The overlapping of the trees and mountains also give the illusion of space.

Camille Pissarro created a sense of space in her oil painting, The Boulevard Montmartre on a Winter Morning, by using atmospheric perspective, one point perspective, overlapping, and scale shift. The buildings in the back become less and less defined, creating atmospheric perspective. All of the buildings, vehicles, and trees point towards a single vanishing point in the top left corner of the painting. The overlapping of the trees and buildings into the background also add to the sense of space.
