Infinity Cove
In photography, an infinity cove or infinity cyclorama is an all-white space with no corners, designed to give the impression that the background of an object extends to infinity. Infinity coves range from a simple roll of paper to whole studios (often used for photographing cars). The principle of design is that everything behind the object is curved so that no edges can be seen.

Photography
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purp ...

Cyclorama (theater)
In theater and film, a cyclorama (abbreviated cyc in the U.S., Canada, and the UK) is a large curtain or wall, often concave, positioned at the back of the apse. It often encircles or partially encloses the stage to form a background. It was popularized in the German theater of the 19th century and continues in common usage today in theaters throughout the world. It can be made of unbleached canvas (larger versions) or muslin (smaller versions), filled scrim (popularized on Broadway in the 20th century), or seamless translucent plastic (often referred to as "Opera Plastic"). Traditionally it is hung at 0% fullness (flat). When possible, it is stretched on the sides and weighted on the bottom to create a flat and even surface. As seams tend to interrupt the smooth surface of the cyclorama, it is usually constructed from extra-wide material. In photography, cycloramas or cycs also refer to curving backdrops which are white to create the illusion of no background, or green for chroma ...

Infinity
Infinity is that which is boundless, endless, or larger than any natural number. It is often denoted by the infinity symbol . Since the time of the ancient Greeks, the philosophical nature of infinity was the subject of many discussions among philosophers. In the 17th century, with the introduction of the infinity symbol and the infinitesimal calculus, mathematicians began to work with infinite series and what some mathematicians (including l'Hôpital and Bernoulli) regarded as infinitely small quantities, but infinity continued to be associated with endless processes. As mathematicians struggled with the foundation of calculus, it remained unclear whether infinity could be considered as a number or magnitude and, if so, how this could be done. At the end of the 19th century, Georg Cantor enlarged the mathematical study of infinity by studying infinite sets and infinite numbers, showing that they can be of various sizes. For example, if a line is viewed as the set of all o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Studio
A studio is an artist or worker's workroom. This can be for the purpose of acting, architecture, painting, pottery (ceramics), sculpture, origami, woodworking, scrapbooking, photography, graphic design, filmmaking, animation, industrial design, radio or television production broadcasting or the making of music. The term is also used for the workroom of dancers, often specified to dance studio. The word ''studio'' is derived from the , from , from ''studere'', meaning to study or zeal. The French term for studio, ''atelier'', in addition to designating an artist's studio is used to characterize the studio of a fashion designer. ''Studio'' is also a metonym for the group of people who work within a particular studio. :uz:Studiya Art studio The studio of any artist, especially from the 15th to the 19th centuries, characterized all the assistants, thus the designation of paintings as "from the workshop of..." or "studio of..."

Automobile
A car or automobile is a motor vehicle with Wheel, wheels. Most definitions of ''cars'' say that they run primarily on roads, Car seat, seat one to eight people, have four wheels, and mainly transport private transport#Personal transport, people instead of cargo, goods. The year 1886 is regarded as the birth year of the car, when German inventor Carl Benz patented his Benz Patent-Motorwagen. Cars became widely available during the 20th century. One of the first cars affordable by the masses was the 1908 Ford Model T, Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced Draft animal, animal-drawn carriages and carts. In Europe and other parts of the world, demand for automobiles did not increase until after World War II. The car is considered an essential part of the Developed country, developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Gradient
In color science, a color gradient specifies a range of position-dependent colors, usually used to fill a region. Name A color gradient is also known as a color ramp or a color progression. In assigning colors to a set of values, a gradient is a continuous colormap, a type of color scheme.
