A technique that uses realistic imagery to create an optical illusion that objects exist in three dimensions. Widely used in wall murals and art to create the illusion of depth and realism.

The phenomenon where the retina retains an image for a fraction of a second after the object is no longer present. This principle is used in filmmaking to create the illusion of continuous motion.

A point in perspective drawing where parallel lines appear to converge, giving the illusion of depth and distance. Used to create a three-dimensional effect on a two-dimensional plane.

The tendency of observers not to notice large changes in a visual scene when the change is accompanied by a visual disruption, such as a brief interruption. Useful for creating transitions in illusions without being detected.

The fact that two adjacent colors affect each other, with the perceived color of one shifting towards the complementary color of the other. Useful in illusions to enhance or change color perception.

Visual designs that exploit flaws in human perception to create images that deceive the brain. Often used in ambiguous or impossible objects to challenge the viewer's reality.

A distorted room that, when viewed through a peephole, appears normal but makes objects seem oddly sized due to the viewer's incorrect depth cues. Used in films and attractions to create size illusions.

A perceptual tendency to perceive objects as remaining the same size despite changes in their distance from the observer. This can be exploited in illusions to create confusion over an object's true size.

A perceptual phenomenon demonstrating an interaction between hearing and vision in speech perception, where a visual stimulus can change what the viewer hears. Applied in creating auditory illusions in conjunction with visual cues.

By manipulating visual cues, objects can appear larger, smaller, farther, or closer than they really are. Used to create seemingly impossible scenarios or to alter perceived distance and size.

The act of conveying a message below the threshold of conscious perception. Used in various media to influence viewers without their explicit awareness.

A technique where background images move by the camera slower than foreground images, creating an illusion of depth. Used in virtual reality and video games to enhance immersion.

An illusion technique that uses glass, special lighting, and reflection to make objects appear, disappear, or morph. Often used in haunted house attractions and magic tricks.

A psychological technique that leads the audience's attention away from a secret action. Utilized to covertly manipulate props or execute a sleight of hand.
