What is areal perspective?

Areal perspective is often referred to as a, 'bird's eye view', usually perceived when looking at a landscape or even cityscape if viewed from say, a plane, or a high building.

On a sunny day, the scene viewed will be sharper and the eye can see even further.

On a cloudy or overcast day the view will be less sharp, often obscured by atmospheric

clouds, mist or fog.

Basic one and two point perspective usually does not apply here as the horizon line

has virtually disappeared because of the viewer is positioned at an extreme height.
