The principle of anamorphic lens for photography

Transfiguration lens is a type of lens that changes the shape of an image through special design, mainly used in movies and photography to create unique visual effects. Its principle is mainly based on optical design and geometric transformation, including the following aspects:
Optical design: Deformable lenses typically contain multiple optical elements, such as cylindrical mirrors and prisms, which compress or stretch the image through non axis rotational symmetry design. This design allows the lens to change the shape of the image during shooting, resulting in a unique visual effect.
Geometric transformation: Deformable lenses change the shape of an image through geometric transformations. This transformation can be achieved through optical elements such as cylindrical mirrors and prisms. A cylindrical mirror can compress or stretch an image vertically or horizontally, while a prism can further adjust the shape of the image.
Historical background: The history of anamorphic lenses can be traced back to the late 19th century, with the earliest patent being registered in 1898. Although it was not widely used in the early days due to technological limitations, in the 1950s, with the development of the film industry, anamorphic lenses gradually became an important visual innovation tool.
Application scenarios: Transfiguration lenses have a wide range of applications in movies and photography. They are commonly used to create a wide field of view, unique visual effects, and immersive viewing experience. By compressing images, deformable lenses can display more surrounding environments and enhance the depth and width of the scene.
Modern applications: Transfiguration lenses are still widely used in modern photography and film production. They are not only used for artistic creation, but also for scientific research and education to showcase complex geometric structures and spatial relationships.
