Intentional Camera Movement
In intentional camera movement (ICM), a camera is moved during the exposure for a creative or artistic effect. This causes the image points to move across the recording medium, producing varied effects such as streaking, textures, and layers in the resulting image. The central idea in ICM photography is that motion serves as the primary compositional element. Strict technical or definitional arguments remain vague in this form of photography which has a long history and is connected with many other forms of photography, such as Impressionism and often blurs genres and styles. Technique The process often involves the selection of a narrow aperture and the use of filters and light to achieve a suitable shutter speed. Proponents experiment both with the duration of the exposure and the direction and amount of camera movement while the shutter is open. Examples of exposures often range from 1/20 to 1/2 second though experimenting with settings often creates unique results. A shut ...

Film Speed
Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to describe the relationship between exposure and output image lightness in digital cameras. Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a ''slow film''. Highly sensitive films are correspondingly termed ''fast films''. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor. Film speed measurement systems His ...

Zoom Burst
Zoom burst is a photographic technique, attainable with zoom lenses with a manual zoom ring. Using the technique involves zooming while the shutter is open with a relatively slow shutter speed, generally below 1/60 of a second. For this reason low light or small apertures are required. It is also possible to achieve a similar effect with either computer software like Adobe Photoshop (after the photo has been shot) or a photographic filter In photography and cinematography, a filter is a camera accessory consisting of an optical filter that can be inserted into the optical path. The filter can be of a square or oblong shape and mounted in a holder accessory, or, more commonly, a .... In these cases the shutter speed can be as fast as necessary. Photographs taken with this technique are characterized by blurred streaks emanating from the center of the photograph. The effect is nearly identical to a motion blur image in which the camera is traveling towards the subject. For th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoom Lens
A zoom lens is a mechanical assembly of lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens (see prime lens). A true zoom lens, also called a parfocal lens, is one that maintains focus when its focal length changes. Most consumer zoom lenses do not maintain perfect focus, but are still parfocal designs. Most camera phones that are advertised as having optical zoom actually use a few cameras of different but fixed focal length, combined with digital zoom to make a hybrid system. The convenience of variable focal length comes at the cost of complexity – and some compromises on image quality, weight, dimensions, aperture, autofocus performance, and cost. For example, all zoom lenses suffer from at least slight, if not considerable, loss of image resolution at their maximum aperture, especially at the extremes of their focal length range. This effect is evident in the corners of the image, when display ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panning (camera)
In cinematography and photography panning means swivelling a still or video camera horizontally from a fixed position. This motion is similar to the motion of a person when they turn their head on their neck from left to right. In the resulting image, the view seems to "pass by" the spectator as new material appears on one side of the screen and exits from the other, although perspective lines reveal that the entire image is seen from a fixed point of view. The term ''panning'' is derived from ''panorama'', suggesting an expansive view that exceeds the gaze, forcing the viewer to turn their head in order to take everything in. Panning, in other words, is a device for gradually revealing and incorporating off-screen space into the image. Panning should never be confused with tracking or "travelling," in which the camera is not just swivelled but is physically displaced left or right, generally by being rolled parallel to its subject. In video technology, panning refers to the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motion Blur
Motion blur is the apparent streaking of moving objects in a photograph or a sequence of frames, such as a film or animation. It results when the image being recorded changes during the recording of a single exposure, due to rapid movement or long exposure. Usages / Effects of motion blur Photography When a camera creates an image, that image does not represent a single instant of time. Because of technological constraints or artistic requirements, the image may represent the scene over a period of time. Most often this exposure time is brief enough that the image captured by the camera appears to capture an instantaneous moment, but this is not always so, and a fast moving object or a longer exposure time may result in blurring artifacts which make this apparent. As objects in a scene move, an image of that scene must represent an integration of all positions of those objects, as well as the camera's viewpoint, over the period of exposure determined by the shutter speed. ...

Kōtarō Tanaka (photographer)
was a Japanese amateur photographer particularly noted for his photography of Osaka and his use of color. Tanaka was born in Ise, Mie (Japan) in 1901.Although ''Shashinka wa nani o hyōgen shita ka'' specifies 4 December 1901, the editors of the two later biographical dictionaries would have known of this book (the article in ''Nihon no shashinka'' explicitly cites it) but the works omit the date for some reason. From 1932 onwards he participated in a variety of amateur photography groups. From 1948 he worked in the Osaka office of '' Asahi Shinbun'''s publishing company. From 1955, Tanaka worked to photograph Kawachi in Osaka, in a series titled ''Kawachi Fūdoki'' (). In 1962 he started photographing firework displays in color (then still unusual for such purposes), with his camera attached to his moving body. Starting in the seventies, Tanaka won a series of awards for his long service to amateur photography in the Kansai The or the , lies in the southern-central re ...

Ernst Haas
Ernst Haas (March 2, 1921 – September 12, 1986) was an Austrian-American photojournalist and color photographer. During his 40-year career, Haas bridged the gap between photojournalism and the use of photography as a medium for expression and creativity. In addition to his coverage of events around the globe after World War II, Haas was an early innovator in color photography. His images were disseminated by magazines like ''Life'' and '' Vogue'' and, in 1962, were the subject of the first single-artist exhibition of color photography at New York's Museum of Modern Art. He served as president of the cooperative Magnum Photos, and his book ''The Creation'' (1971) was one of the most successful photography books ever, selling 350,000 copies. Early life and education Haas was born in Vienna, Austria, on March 2, 1921. He was the son of Ernst Haas, a high-level civil servant, and Frederike Haas-Zipser. He had an older brother named Fritz Haas. Haas was raised in the cultura ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stops (Dynamic Range)
In photography, exposure range may refer to any of several types of dynamic range: * The '' light sensitivity range'' of photographic film, paper, or digital camera sensors. * The ''luminosity range'' of a scene being photographed. * The ''opacity range'' of developed film images * The ''reflectance range'' of images on photographic papers. The exposure range of a device is usually expressed in stops, which are equivalent to \log_ (c) where ''c'' is the medium or device's contrast ratio. For example, average Digital Video (DV) has a contrast ratio of 45:1, so its exposure range is roughly 5.5 stops. Film has an exposure range of approximately 14 stops. Exposure is usually controlled by changing the lens aperture (the amount of light it gathers), the shutter speed (how long light is gathered) or sensitivity (how strongly the film or sensor responds to light). Changing exposure does not change the exposure range. A graduated neutral density filter can be also used to improve t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camera
A camera is an optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera domain are film, videography, and cinematograph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
