How did Renaissance artists master optical perspective?

Perspective is a graphical projection technique that represents three-dimensional scenes on a flat surface by making objects appear smaller with distance. During the Italian Renaissance, artists and architects studied these optical principles and wrote treatises on them. Devices like the camera obscura also helped creators achieve accurate graphical perspective in their work.

What we know

• Perspective is an approximate representation of a three-dimensional scene on a two-dimensional medium based on how objects appear to the eye. [2]
• Linear perspective features objects appearing smaller as their distance from the observer increases, alongside foreshortening effects. [2]
• Italian Renaissance figures such as Filippo Brunelleschi, Leon Battista Alberti, and Leonardo da Vinci studied linear perspective and incorporated it into their art. [2]
• Camera obscuras were used as drawing aids to trace projected images and achieve proper graphical perspective. [5]
