Atmospheric perspective is a technique used in art and photography to create the illusion of depth and distance. It relies on the way the atmosphere affects the appearance of objects as they recede into the background. Distant objects often appear lighter, less detailed, and more bluish in color due to the scattering of light by air particles. This method is commonly seen in landscape paintings, where artists like Leonardo da Vinci and Claude Monet employed it to enhance realism. By manipulating color and clarity, they effectively guided the viewer's eye through the composition, making foreground elements appear closer and background elements more distant.
