Light plays a decisive role in human life. Our brain sees the world around thanks to the light reflected from various objects. And the artist must understand the laws of falling and scattering of light on the surfaces.
Observing objects from different distances, we see that the perception of these objects is changing. As objects move away from us, they appear less clear and crisp, and their color seems different than at the close range.
Linear perspective is a science that teaches us to depict objects of the visible world on the plane in accordance with the seeming changes in their size, shape, and clarity, due to the degree of remoteness from the observation point.
