The introduction of optical illusion photography is as follows:

Illusion photography is a type of conceptual photography that emerged at the end of the 20th century. A category in which artists usually create based on the principles of Gestalt and illusion psychology. In photography, we create the scene we want to shoot by arranging the situation, and shoot from a special viewpoint to question reality and explore the possibility of visual language.

The introduction to photography is as follows:

Photography (English: photography) refers to the process of recording images using certain specialized equipment. Generally, we use mechanical cameras or digital cameras for still picture photography, and still photography is also called photography.

The camera (camera player) can take dynamic photography, such as TV and movies. At present, some digital cameras and digital video cameras have the functions of both static photography and dynamic photography.

In photography, a camera or camera obscura is usually used as the photographic equipment, and optical film or digital memory card is used as the recording medium. But there are exceptions. For example, Man Ray's rayographs used shadows to create images on photographic paper without the need for a camera.

In the era of postmodern simulacra vision, the proliferation of digital and the fast food of visual culture have caused some artists to reconsider the nature of photography and vision. Illusion photography strives to get rid of the shortness, convenience, and turmoil that postmodern life brings to people. The works often use the components of dual vision to allow people to return to their hearts and their true selves again. It takes a lot of work and time for optical illusion artists to take a photo, sometimes as long as ten years apart.

Most photography uses a series of lenses to refract and focus light onto film or CCD optical sensing media. The film itself is also a storage medium, storing signals through chemical changes. The CCD converts light into electronic signals and stores them in a digital memory card.

The stored signals can be restored to optical information through certain methods and then viewed with photos or monitors. In addition to lenses composed of lenses, a few lenses are composed of reflectors or reflectors combined with lenses.
