Air perspective in photography

One of the methods of expressing spatial depth in photography. When light passes through the atmosphere, because of the diffusion of light by air medium, scenes with different spatial distances are different in contrast between light and shade, outline clarity, color saturation and so on. This phenomenon forms a tone perspective effect in the photo, thus showing the spatial depth and the spatial position of the object. Backlight, side backlight, smoke and special filters are often used in photography to enhance the perspective effect of tone modulation.

This kind of air perspective effect usually appears in the morning and evening when the humidity is high, and the time is short, so most photographers must know the general situation of the shooting place and take the form of crouching to shoot. However, if we can skillfully use the light, such as looking for shelter in front of the light, it is easy to get a picture effect similar to air perspective. Using light to create an air perspective-like effect to form an air perspective-like picture is mainly done by backlight and side backlight. In addition, by controlling the light, the scene is nearly dark and far bright, which can also form an effect similar to aerial perspective.
