The art of optical illusion, also well-known as OP art, is a mathematical genre which produces optical illusions. This art uses the repetition of form and color to create moving patterns that result to illusions. It also distorts the human sense of depth, leading to background confusion in the foreground, as well as other disconcerting effects.
How does Op Art Illusion work?
A human mind looks for patterns in everything he sees. For example, if we see a car full of design triangles, we will always try to count the number of triangles in the vehicle. That is because, from the beginning, our mind is trained in such a way that it works to match the patterns. A human spirit cannot resist the temptation to unite shapes and angles. It is on which feeds an optical illusion, the so-called conscious human mind.
The brain is always trying to find some continuity or connection in what the eyes see. An optical illusion works to show some connectivity at the surface. These illusions benefit from the fact that human beings have performed illusions and perceptions. As soon as our minds see something familiar, they return to the past and associate this familiarity with a particular form or design.
Therefore, visual perception, which is the basis of many discoveries and inventions. Different receptors in the eyes sometimes form different minor images, and when all these different incoherent images come together in mind to create a coherent vision, a false or duplicate image is formed. There are three types of color interaction used when creating an Op art:
Simultaneous Contrast: Happens when one color area is surrounded by another color to make a difference in brightness. However, when one area of color is more intense and brighter than the other, the contrast will go out of balance and will seem to go in one direction.
Successive Contrast: Occurs when a color is straightaway followed by an extra color, rapidly changing the viewer’s focus from one color area to another.
Reverse Contrast: Occurs when the brightness of the white or darkness of the black appears to extend to neighboring regions, making the colors to diffuse together.
Necessary Steps in Making Op Art
The art of optical illusion requires scientific ingenuity, technical skills and meticulous planning. Because he manipulates the rules of perception, a spectator trying to decipher such a painting can observe movements, hidden images, three-dimensional shapes and other simulations. All elements used to produce an illusory coin, lines, shapes and colors, must be carefully selected so that their combination achieves the desired maximum effect. There are two necessary steps in Making Op Art.
The first, and perhaps the most commonly accepted, a method is to use lines and patterns, often in black and white, that produce illusory images.
The second is with color, using the same pattern elements, but this produces additional effects in the viewer’s eye and produces a different dimension.
Optical illusions use the forces of the human brain to nullify their forces. This illusion is a by-product of faulty judgment/perception coupled with anticipatory vision. Sometimes the human mind erroneously calculates an incorrect distance from the object, and this forms a false image in the brain.
