Anamorphosis is a distorted projection or perspective requiring the viewer to occupy a specific vantage point, use special devices or both to view a recognizable image. Some of the media it is used in are painting, photography, sculpture and installation, toys, and film special effects. The word "anamorphosis" is derived from the Greek prefix ana‑, meaning " back " or "again", and the word morphe, meaning " shape " or " form ". An optical anamorphism is the visualization of a mathematical operation called an affine transformation. The process of extremeanamorphosis has been used by artists to disguise caricatures, erotic and scatological scenes, and other furtive images from a casual viewer, while revealing an undistorted image to the knowledgeable spectator.
Types of projection
There are two main types of anamorphosis: perspective (oblique) and mirror (catoptric). More-complex anamorphoses can be devised using distorted lenses, mirrors, or other optical transformations.
Examples of perspectival anamorphosis date to the early Renaissance (fifteenth century). The first examples were largely related to religious themes.With mirror anamorphosis, a conical or cylindrical mirror is placed on the drawing or painting to transform a flat distorted image into an apparently undistorted picture. The deformed image is created by using the laws of the angles of the incidence of reflection.
