The architects of the Parthenon adjusted the plans so that the major lines of any significant building are rarely straight. The most obvious adjustment is to the profile of columns, which narrow from base to top. However, the narrowing is not regular, but gently curved so that each columns appears to have a slight swelling, called entasis below the middle. But this entasis is never so pronounced as to make the swelling wider than the base; it is controlled by a slight reduction in the rate of decrease of diameter.

Optical illusions are everywhere, and in this digital era, we see skilled photographers using amazing cameras techniques and equipment to shoot photos that are modifying the scales of two objects, making one smaller than the other; to create an amazing whole picture.
However, do you know what this camera technique is called and what is its origin? Find out more below.
The technique of forcing people to perceive objects in a different manner than is possible in reality is actually an art form known as 'forced perspective'. The technique of forced perspective has been around for quite a while and has been used throughout history by various artists to make their work come to life and become truly unique.
The trick behind this art form is to scale objects to different sizes so that a sense of depth can be created and perceived within the paintings.
Forced perspective plays with the visual perception of humans and creates an optical illusion that is life-like, making it seem like reality.
Types of Forced Perspective
Employing forced perspective, an artist can make objects seem larger, smaller, nearer, or farther than they truly are, creating an illusion within a picture. For instance, two people of equal height may be depicted at varying depths in the canvas; making one seem taller and closer than the other.
Additionally, the use of forced perspective can also merge two objects with each other within a picture or bend the laws of gravity to show people walking on the surface of water or sitting on air.
Although forced perspective does not create the illusion of three-dimensional objects, it is still a highly used art form that has been able to trick people into believing impossible occurrences and pictures.
However, art is not the only way to display the technique of forced perspective. Filmmaking, photography, architecture, and art, all have an equal share in the development of this technique.
Forced Perspective in History
Forced perspective is a form that was commonly used by the Greeks in architecture. Simply by creating their columns to be narrower at the top rather than at the bottom, allowed them to provide the illusion of a higher and vast space to their structures. This technique is also used in theatres today to depict a larger space in the interior.
As mentioned previously, in spite of the wide use of forced perspective in art forms over time, today, the technique is being used in photography and films to create optical illusions that are unbelievable.
Some of the most common forced perspectives of today’s time include:
Forced perspective as an art is clearly seen in historically famous paintings, where it creates believable illusions. This technique, though modified continues in today’s world, fooling people into believing in the impossible.
