Perspective; All you need to know about.

Perspective is a method for reproducing realistic pictures. It is a mathematical system that indicates how a real-world scene would project to a vantage (vanishing) point. Perspective pictures look realistic because they recreate the pattern of light of the real-world scene.

An observer looking at the painting “The School of Athens” by Raphael (bellow, an example of 1 point perspective) gets an impression similar to that from observing a real scene in Athens. In other words, the painting looks realistic. This realism is provided by perspective. It is an approximate representation, on a flat surface (such as paper), of an image as it is perceived by the eye. The most common characteristic featured in perspective is that objects are drawn smaller as the distance from the observer increases.

Of the many types of perspective drawings, the most common categorizations of artificial perspective are one-, two- and three-point. The names of these categories refer to the number of vanishing points in the perspective drawing.

One-point perspective Examples:

Two-point perspective

Three-point perspective
