Reverse Perspective
Reverse perspective, also called inverse perspective,. inverted perspective, divergent perspective, or Byzantine perspective, is a form of perspective (graphical), perspective drawing where the objects depicted in a scene are placed between the projective point and the viewing plane. Objects further away from the viewing plane are drawn as larger, and closer objects are drawn as smaller, in contrast to the more conventional linear perspective where closer objects appear larger.. Lines that are parallel in three-dimensional space are drawn as diverging against the horizon, rather than converging as they do in linear perspective. Technically, the vanishing points are placed outside the painting with the illusion that they are "in front of" the painting. The name Byzantine perspective comes from the use of this perspective in Byzantine art, Byzantine and Russian Orthodox Church, Russian Orthodox icons; it is also found in the art of many pre-Renaissance cultures, and was sometimes ...

Hypercentric Lens
A hypercentric or pericentric lens is a lens system where the entrance pupil is located in front of the lens, in the space where an object could be located. In a certain region, objects that are further away from the lens produce larger images than objects that are closer to the lens. This is in stark contrast to the behavior of the human eye or any ordinary camera (both entocentric lenses), where further-away objects always appear smaller. The geometry of a hypercentric lens can be visualized by imagining a point source of light at the center of the entrance pupil sending rays in all directions. Any point on the object will be imaged to the point on the image plane found by continuing the ray that passes through it, so the shape of the image will be the same as the shadow cast by the object from the imaginary point of light. The closer an object gets to that point (the center of the entrance pupil), the larger its image will be. This inversion of normal perspectivity can be us ...

Perspective (graphical)
Linear or point-projection perspective () is one of two types of graphical projection perspective in the graphic arts; the other is parallel projection. Linear perspective is an approximate representation, generally on a flat surface, of an image as it is seen by the eye. Perspective drawing is useful for representing a three-dimensional scene in a two-dimensional medium, like paper. It is based on the optical fact that for a person an object looks N times (linearly) smaller if it has been moved N times further from the eye than the original distance was. The most characteristic features of linear perspective are that objects appear smaller as their distance from the observer increases, and that they are subject to , meaning that an object's dimensions parallel to the line of sight appear shorter than its dimensions perpendicular to the line of sight. All objects will recede to points in the distance, usually along the horizon line, but also above and below the horiz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Byzantine Art
Byzantine art comprises the body of artistic products of the Eastern Roman Empire, as well as the nations and states that inherited culturally from the empire. Though the empire itself emerged from the decline of Rome, decline of western Rome and lasted until the Fall of Constantinople in 1453, the start date of the Byzantine period is rather clearer in art history than in political history, if still imprecise. Many Eastern Orthodox states in Eastern Europe, as well as to some degree the Islamic states of the eastern Mediterranean, preserved many aspects of the empire's culture and art for centuries afterward. A number of contemporary states with the Eastern Roman (Byzantine) Empire were culturally influenced by it without actually being part of it (the "Byzantine commonwealth"). These included Kievan Rus', as well as some non-Orthodox states like the Republic of Venice, which separated from the Byzantine Empire in the 10th century, and the Norman-Arab-Byzantine culture, Kingdom o ...

Russian Orthodox Church
The Russian Orthodox Church (ROC; ;), also officially known as the Moscow Patriarchate (), is an autocephaly, autocephalous Eastern Orthodox Church, Eastern Orthodox Christian church. It has 194 dioceses inside Russia. The Primate (bishop), primate of the ROC is the patriarch of Moscow and all Rus'. The History of the Russian Orthodox Church, history of the ROC begins with the Christianization of Kievan Rus', which commenced in 988 with the baptism of Vladimir the Great and his subjects by the clergy of the Ecumenical Patriarch of Constantinople, ecumenical patriarch of Constantinople. Starting in the 14th century, Moscow served as the primary residence of the Russian List of metropolitans and patriarchs of Moscow, metropolitan. The ROC declared autocephaly in 1448 when it elected its own metropolitan. In 1589, the metropolitan was elevated to the position of patriarch with the consent of Constantinople. In the mid-17th century, a series of reforms led to Schism of the Russian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Icon
An icon () is a religious work of art, most commonly a painting, in the cultures of the Eastern Orthodox, Oriental Orthodox, Catholic Church, Catholic, and Lutheranism, Lutheran churches. The most common subjects include Jesus, Mary, mother of Jesus, Mary, saints, and angels. Although especially associated with portrait-style images concentrating on one or two main figures, the term also covers most of the religious images in a variety of artistic media produced by Eastern Christianity, including narrative scenes, usually from the Bible or the lives of saints. Icons are most commonly painted on wood panels with egg tempera, but they may also be cast in metal or carved in stone or embroidered on cloth or done in mosaic or fresco work or printed on paper or metal, etc. Comparable images from Western Christianity may be classified as "icons", although "iconic" may also be used to describe the static style of a devotional image. In the Greek language, the term for icon painting uses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cubism
Cubism is an early-20th-century avant-garde art movement which began in Paris. It revolutionized painting and the visual arts, and sparked artistic innovations in music, ballet, literature, and architecture. Cubist subjects are analyzed, broken up, and reassembled in an abstract form. Instead of depicting objects from a single perspective, the artist depicts the subject from multiple perspectives to represent the subject in a greater context. Cubism has been considered the most influential art movement of the 20th century. The term ''cubism'' is broadly associated with a variety of artworks produced in Paris (Montmartre and Montparnasse) or near Paris (Puteaux) during the 1910s and throughout the 1920s. The movement was pioneered in partnership by Pablo Picasso and Georges Braque, and joined by Jean Metzinger, Albert Gleizes, Robert Delaunay, Henri Le Fauconnier, Juan Gris, and Fernand Léger. One primary influence that led to Cubism was the representation of three-dimensional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modern Art
Modern art includes artistic work produced during the period extending roughly from the 1860s to the 1970s, and denotes the styles and philosophies of the art produced during that era. The term is usually associated with art in which the traditions of the past have been thrown aside in a spirit of experimentation. Modern artists experimented with new ways of seeing and with fresh ideas about the nature of materials and functions of art. A tendency away from the narrative, which was characteristic of the traditional arts, toward abstraction is characteristic of much modern art. More recent artistic production is often called contemporary art or Postmodern art. Modern art begins with the post-impressionist painters like Vincent van Gogh, Paul Cézanne, Paul Gauguin, Georges Seurat and Henri de Toulouse-Lautrec. These artists were essential to modern art's development. At the beginning of the 20th century Henri Matisse and several other young artists including the Proto-Cubism, pre ...

Telecentric Lens
A telecentric lens is a special optical lens (often an objective lens or a camera lens) that has its entrance or exit pupil, or both, at infinity. The size of images produced by a telecentric lens is insensitive to either the distance between an object being imaged and the lens, or the distance between the image plane and the lens, or both, and such an optical property is called ''telecentricity''. Telecentric lenses are used for precision optical two-dimensional measurements, reproduction (e.g., photolithography), and other applications that are sensitive to the image magnification or the angle of incidence of light. The simplest way to make a lens telecentric is to put the aperture stop at one of the lens's focal points. This allows only rays including the chief rays (light rays that pass through the center of the aperture stop), that will be about parallel to the optical axis on the other side of the lens, to pass the optical system for any object point in the field of view. ...
