Phantogram (optical Illusion)
Phantograms, also known as Phantaglyphs, Op-Ups, free-standing anaglyphs, levitated images, and book anaglyphs, are a form of optical illusion. Phantograms use perspectival anamorphosis to produce a 2D image that is distorted in a particular way so as to appear, to a viewer at a particular vantage point, three-dimensional, standing above or recessed into a flat surface. The illusion of depth and perspective is heightened by stereoscopy techniques; a combination of two images, most typically but not necessarily an anaglyph (color filtered stereo image). With common (red–cyan) 3D glasses, the viewer's vision is segregated so that each eye sees a different image. Phantograms can be created using drawn images, photographs, or computer-generated images. Phantograms are usually placed horizontally and are intended to be viewed standing back from the image, though they can also be placed vertically and viewed at an angle from above or below. Principle Phantograms work by presenti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optical Illusion
Within visual perception, an optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual perception, percept that arguably appears to differ from reality. Illusions come in a wide variety; their categorization is difficult because the underlying cause is often not clear but a classification proposed by Richard Gregory is useful as an orientation. According to that, there are three main classes: physical, physiological, and cognitive illusions, and in each class there are four kinds: Ambiguities, distortions, paradoxes, and fictions. A classical example for a physical distortion would be the apparent bending of a stick half immerged in water; an example for a physiological paradox is the motion aftereffect (where, despite movement, position remains unchanged). An example for a physiological fiction is an afterimage. Three typical cognitive distortions are the Ponzo illusion, Ponzo, Poggendorff illusion, Poggendorff, an ...

Trompe-l'œil
''Trompe-l'œil'' ( , ; ) is an artistic term for the highly realistic optical illusion of three-dimensional space and objects on a two-dimensional surface. ''Trompe l'oeil'', which is most often associated with painting, tricks the viewer into perceiving painted objects or spaces as real. Forced perspective is a related illusion in architecture. History in painting The phrase, which can also be spelled without the hyphen and ligature in English as ''trompe l'oeil'', originates with the artist Louis-Léopold Boilly, who used it as the title of a painting he exhibited in the Paris Salon of 1800. Although the term gained currency only in the early 19th century, the illusionistic technique associated with ''trompe-l'œil'' dates much further back. It was (and is) often employed in murals. Instances from Greek and Roman times are known, for instance in Pompeii. A typical ''trompe-l'œil'' mural might depict a window, door, or hallway, intended to suggest a larger room. A ver ...

Trademark
A trademark (also written trade mark or trade-mark) is a type of intellectual property consisting of a recognizable sign, design, or expression that identifies products or services from a particular source and distinguishes them from others. The trademark owner can be an individual, business organization, or any legal entity. A trademark may be located on a package, a label, a voucher, or on the product itself. Trademarks used to identify services are sometimes called service marks. The first legislative act concerning trademarks was passed in 1266 under the reign of Henry III of England, requiring all bakers to use a distinctive mark for the bread they sold. The first modern trademark laws emerged in the late 19th century. In France, the first comprehensive trademark system in the world was passed into law in 1857. The Trade Marks Act 1938 of the United Kingdom changed the system, permitting registration based on "intent-to-use", creating an examination based pro ...

Photo Manipulation
Photograph manipulation involves the transformation or alteration of a photograph using various methods and techniques to achieve desired results. Some photograph manipulations are considered to be skillful artwork, while others are considered to be unethical practices, especially when used to deceive the public. Other examples include being used for political propaganda, or to improve the appearance of a product or person, or simply as entertainment or practical jokes. Depending on the application and intent, some photograph manipulations are considered an art form because it involves the creation of unique images and in some instances, signature expressions of art by photographic artists. Ansel Adams employed some of the more common manipulations using darkroom exposure techniques, burning (darkening) and dodging (lightening) a photograph. Other examples of photo manipulation include retouching photographs using ink or paint, airbrushing, double exposure, piecing photo ...

Technical Drawing
Technical drawing, drafting or drawing, is the act and Academic discipline, discipline of composing Plan (drawing), drawings that Visual communication, visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in Manufacturing, industry and engineering. To make the drawings easier to understand, people use familiar symbols, Perspective (graphical), perspectives, units of measurement, notation systems, visual styles, and page layout. Together, such Convention (norm), conventions constitute a visual language and help to ensure that the drawing is unambiguous and relatively easy to understand. Many of the symbols and principles of technical drawing are codified in an international standard called ISO 128. The need for precise communication in the preparation of a functional document distinguishes technical drawing from the expressive drawing of the visual arts. Artistic drawings are subjectively interpreted; their meanin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julian Beever
Julian Beever (born c. 1959) is a British sidewalk chalk artist who has been creating ''trompe-l'œil'' chalk drawings on pavement surfaces since the mid-1990s. He uses a projection technique called anamorphosis to create the illusion of three dimensions when viewed from the correct angle. He preserves his work in photographs, often positioning a person within the image as if they were interacting with the scene. Biography Beever grew up in Melton, Leicestershire, near the geographical centre of England. His talent in drawing had emerged by the time he was 5 years old; he liked school, especially his art classes(optical illusion). At the age of 18, he chose to study art, design, and psychology (as a last-minute substitute for English). He continued to excel in art, found design to be tedious, and discovered new insights into visual perception, depth perception, and the eye and brain in his psychology studies. After a gap year working as a laborer and carpet-layer's assistan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kurt Wenner
Kurt Wenner is an American artist, he is known for his 3D pavement art shown internationally. Early life and education Wenner was born in Ann Arbor, Michigan in 1958, but grew up in Santa Barbara, California. He attended Rhode Island School of Design and ArtCenter College of Design in California. While at ArtCenter he was recruited to work for NASA at the Jet Propulsion Laboratory, creating conceptual art. In 1982, he left his job at NASA to focus on his art and moved to Italy. Career Wenner learned about the European tradition of street painting after living in Rome for a few months. Wenner added perspective to the street painting work and in turn he created 3D pavement art. His work has been shown in more than 30 countries around the world. In 2010, Greenpeace Greenpeace is an independent global campaigning network, founded in Canada in 1971 by Irving Stowe and Dorothy Stowe, immigrant environmental activists from the United States.

Andrea Pozzo
Andrea Pozzo (; Latinized version: ''Andreas Puteus''; 30 November 1642 – 31 August 1709) was an Italian Jesuit brother, Baroque painter, architect, decorator, stage designer, and art theoretician. Pozzo was best known for his grandiose frescoes using the technique of quadratura to create an illusion of three-dimensional space on flat surfaces. His masterpiece is the nave ceiling of the Church of Sant'Ignazio in Rome. Through his techniques, he became one of the most noteworthy figures of the Baroque period. He is also noted for the architectural plans of Ljubljana Cathedral (1700), inspired by the designs of the Jesuit churches Il Gesù and S. Ignazio in Rome. Biography Early years Born in Trento (then under Austrian rule), he studied Humanities at the local Jesuit High School. Showing artistic inclinations he was sent by his father to work with an artist; Pozzo was then 17 years old (in 1659). Judging by aspects of his early style this initial artistic training came p ...

Renaissance
The Renaissance ( , ) , from , with the same meanings. is a period in European history marking the transition from the Middle Ages to modernity and covering the 15th and 16th centuries, characterized by an effort to revive and surpass ideas and achievements of classical antiquity. It occurred after the Crisis of the Late Middle Ages and was associated with great social change. In addition to the standard periodization, proponents of a "long Renaissance" may put its beginning in the 14th century and its end in the 17th century. The traditional view focuses more on the early modern aspects of the Renaissance and argues that it was a break from the past, but many historians today focus more on its medieval aspects and argue that it was an extension of the Middle Ages. However, the beginnings of the period – the early Renaissance of the 15th century and the Italian Proto-Renaissance from around 1250 or 1300 – overlap considerably with the Late Middle Ages, conventi ...

Anaglyph Image
Anaglyph 3D is the stereoscopic 3D effect achieved by means of encoding each eye's image using filters of different (usually chromatically opposite) colors, typically red and cyan. Anaglyph 3D images contain two differently filtered colored images, one for each eye. When viewed through the "color-coded" "anaglyph glasses", each of the two images reaches the eye it's intended for, revealing an integrated stereoscopic image. The visual cortex of the brain fuses this into the perception of a three-dimensional scene or composition. Anaglyph images have seen a recent resurgence due to the presentation of images and video on the Web, Blu-ray Discs, CDs, and even in print. Low cost paper frames or plastic-framed glasses hold accurate color filters that typically, after 2002, make use of all 3 primary colors. The current norm is red and cyan, with red being used for the left channel. The cheaper filter material used in the monochromatic past dictated red and blue for convenience a ...

Anamorphosis
Anamorphosis is a distorted projection requiring 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 Renaissance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
