Perspective Distortion (photography)
In photography and cinematography, perspective distortion is a warping or transformation of an object and its surrounding area that differs significantly from what the object would look like with a normal lens, normal focal length, due to the relative scale of nearby and distant features. Perspective distortion is determined by the relative distances at which the image is captured and viewed, and is due to the angle of view of the image (as captured) being either wider or narrower than the angle of view at which the image is viewed, hence the apparent relative distances differing from what is expected. Related to this concept is axial magnification – the perceived depth of objects at a given magnification. Perspective distortion takes two forms: ''extension distortion'' and ''compression distortion,'' also called ''wide-angle distortion'' and ''long-lens'' or ''telephoto distortion,'' when talking about images with the same field size. Extension or wide-angle distortion can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camera Focal Length Distance House Animation
A camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research. The invention of the camera dates back to the 19th century and has since evolved with advancements in technology, leading to a vast array of types and models in the 21st century. Cameras function through a combination of multiple mechanical components and principles. These include exposure control, which regulates the amount of light reaching the sensor or film; the lens, which focuses the light; the viewfinder, which allows the user to preview the scene; and the film or sensor, which captures the image. Several types of camera exist, each suited to specific uses and offering unique cap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photo Finish
A photo finish occurs in a sporting race when multiple competitors cross the finishing line at nearly the same time. As the naked eye may not be able to determine which of the competitors crossed the line first, a photo or video taken at the finish line may be used for a more accurate check. Photo finishes make it less likely that officials will declare a race a dead heat (racing), dead heat. Finish line photos are still used in nearly every modern racing sport. Although some sports use electronic equipment to track the racers during a race, a photo is considered the most important evidence in selecting the winner. They are especially important during close races, but they are also used to assign official times to each competitor during any race. Method of capture Strip photography Photo-finish cameras were developed during the 1940s and 1950s as a means of regulating the racing industry and to reduce cheating. Betting on races became increasingly popular during the middle dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaussian Optics
Gaussian optics is a technique in geometrical optics that describes the behaviour of light rays in optical systems by using the paraxial approximation, in which only rays which make small angles with the optical axis of the system are considered. In this approximation, trigonometric functions can be expressed as linear functions of the angles. Gaussian optics applies to systems in which all the optical surfaces are either flat or are portions of a sphere. In this case, simple explicit formulae can be given for parameters of an imaging system such as focal length, magnification and brightness, in terms of the geometrical shapes and material properties of the constituent elements. Gaussian optics is named after mathematician and physicist Carl Friedrich Gauss, who showed that an optical system can be characterized by a series of Cardinal point (optics), cardinal points, which allow one to calculate its optical properties.W.J.

Salvador Dalí
Salvador Domingo Felipe Jacinto Dalí i Domènech, Marquess of Dalí of Púbol (11 May 190423 January 1989), known as Salvador Dalí ( ; ; ), was a Spanish Surrealism, surrealist artist renowned for his technical skill, precise draftsmanship, and the striking and bizarre images in his work. Born in Figueres in Catalonia, Dalí received his formal education in fine arts in Madrid. Influenced by Impressionism and the Renaissance art, Renaissance masters from a young age, he became increasingly attracted to Cubism and avant-garde movements. He moved closer to Surrealism in the late 1920s and joined the Surrealist group in 1929, soon becoming one of its leading exponents. His best-known work, ''The Persistence of Memory'', was completed in August 1931. Dalí lived in France throughout the Spanish Civil War (1936 to 1939) before leaving for the United States in 1940 where he achieved commercial success. He returned to Spain in 1948 where he announced his return to the Catholic fai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
André Kertész
André Kertész (; 2 July 1894 – 28 September 1985), born Andor Kertész (), was a Hungarian-born photographer known for his groundbreaking contributions to photographic composition (visual arts), composition and the photo essay. In the early years of his career, his then-unorthodox camera angles and style prevented his work from gaining wider recognition. Kertész never felt that he had gained the worldwide recognition he deserved. Today he is considered one of the seminal figures of 20th century photography. Expected by his family to work as a stockbroker, Kertész pursued photography independently as an Autodidacticism, autodidact, and his early work was published primarily in magazines, a major market in those years. This continued until much later in his life, when Kertész stopped accepting commissions. He served briefly in World War I and moved to Paris in 1925, then the artistic capital of the world, against the wishes of his family. In Paris he worked for France's fi ...

Hans Holbein The Younger
Hans Holbein the Younger ( , ; ; – between 7 October and 29 November 1543) was a German-Swiss painter and printmaker who worked in a Northern Renaissance style, and is considered one of the greatest portraitists of the 16th century. He also produced religious art, satire, and Reformation propaganda, and he made a significant contribution to the history of book design. He is called "the Younger" to distinguish him from his father Hans Holbein the Elder, an accomplished painter of the International Gothic, Late Gothic school. Holbein was born in Augsburg but worked mainly in Basel as a young artist. At first, he painted murals and religious works, and designed stained glass windows and illustrations for books from the printer Johann Froben. He also painted an occasional portrait, making his international mark with portraits of humanist Desiderius Erasmus of Rotterdam. When the Reformation reached Basel, Holbein worked for reformist clients while continuing to serve traditi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anamorphosis
Anamorphosis is a distorted projection that requires the viewer to occupy a specific vantage point, use special devices, or both to view a recognizable image. It is used in painting, photography, sculpture and installation, toys, and film special effects. The word is derived from the Greek prefix ''ana-'', meaning "back" or "again", and the word ''morphe'', meaning "shape" or "form". Extreme anamorphosis has been used by artists to disguise caricatures, erotic and scatological scenes, and other furtive images from a casual spectator, while revealing an undistorted image to the knowledgeable viewer. 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. An oblique anamorphism forms an affine transformation of the subject. Early examples of Perspective (graphical), perspectival anamorphosis date to the Renaissa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leonardo Da Vinci
Leonardo di ser Piero da Vinci (15 April 1452 - 2 May 1519) was an Italian polymath of the High Renaissance who was active as a painter, draughtsman, engineer, scientist, theorist, sculptor, and architect. While his fame initially rested on his achievements as a painter, he has also become known for #Journals and notes, his notebooks, in which he made drawings and notes on a variety of subjects, including anatomy, astronomy, botany, cartography, painting, and palaeontology. Leonardo is widely regarded to have been a genius who epitomised the Renaissance humanism, Renaissance humanist ideal, and his List of works by Leonardo da Vinci, collective works comprise a contribution to later generations of artists matched only by that of his younger contemporary Michelangelo. Born out of wedlock to a successful notary and a lower-class woman in, or near, Vinci, Tuscany, Vinci, he was educated in Florence by the Italian painter and sculptor Andrea del Verrocchio.

Leon Battista Alberti
Leon Battista Alberti (; 14 February 1404 – 25 April 1472) was an Italian Renaissance humanist author, artist, architect, poet, Catholic priest, priest, linguistics, linguist, philosopher, and cryptography, cryptographer; he epitomised the nature of those identified now as polymaths. He is considered the founder of European cryptography, a claim he shares with Johannes Trithemius. He is often considered primarily an architect. However, according to James Beck, "to single out one of Leon Battista's 'fields' over others as somehow functionally independent and self-sufficient is of no help at all to any effort to characterize Alberti's extensive explorations in the fine arts". Although Alberti is known mostly as an artist, he was also a mathematician and made significant contributions to that field. Among the most famous buildings he designed are the churches of San Sebastiano (1460) and Sant'Andrea (1472), both in Mantua. Alberti's life was told in Giorgio Vasari's ''Lives of t ...

Filippo Brunelleschi
Filippo di ser Brunellesco di Lippo Lapi (1377 – 15 April 1446), commonly known as Filippo Brunelleschi ( ; ) and also nicknamed Pippo by Leon Battista Alberti, was an Italian architect, designer, goldsmith and sculptor. He is considered to be a founding father of Renaissance architecture. He is recognized as the first modern engineer, planner, and sole construction supervisor. In 1421, Brunelleschi became the first person to receive a patent in the Western world. He is most famous for designing the dome of the Florence Cathedral, and for the mathematical technique of linear perspective in art which governed pictorial depictions of space until the late 19th century and influenced the rise of modern science. His accomplishments also include other architectural works, sculpture, mathematics, engineering, and ship design. Most surviving works can be found in Florence.
