Encyclopedia > Atmospheric perspective

Aerial perspective or atmospheric perspective is the effect on the appearance of an object by air between it and a viewer. As the distance between an object and a viewer increases, the contrast between the object and its background decreases. The contrast of any markings or details on the object also decreases. The colours of the object also become less saturated and shift towards blue. In visual perception, contrast is the difference in visual properties that makes an object (or its representation in an image) distinguishable from other objects and the background. ... The term saturation generally means thoroughly full, and can refer to the following: In chemistry, see saturation (chemistry) for a number of meanings. ... Blue (from Old High German blao shining) is one of the three primary additive colors; blue light has the shortest wavelength range (about 420-490 nm) of the three primary colors. ...


The major component affecting the appearance of objects during daylight is scattering of light, called sky light, into the line of sight of the viewer. This adds the sky light as a veiling luminance onto the light from the object, reducing its contrast with the background sky light. Skylight usually contains more short wavelength light than other wavelengths (this is why the sky usually appears blue), which is why distant objects appear bluish. A minor component is scattering of light out of the line of sight of the viewer. Under daylight, this either augments the contrast loss (e.g., for white objects) or opposes it (for dark objects). At night there is effectively no skylight (unless the moon is very bright), so scattering out of the line of sight becomes the major component affecting the appearance of self-luminous objects. Such objects have their contrasts reduced with the dark background, and their colours are shifted towards red. The term Daylight can have several meanings: Sunlight The title of an album - Daylight (album) The title of a movie - Daylight (movie) The Southern Pacific railroad operated several named passenger trains named [adjective] Daylight (such as the Afternoon Daylight) in California. ... In particle physics, scattering is a class of phenomena by which particles are deflected by collisions with other particles. ... See also: line of sight in gaming, referring to visibility of units. ... For other uses, see Sky (disambiguation). ... The term Daylight can have several meanings: Sunlight The title of an album - Daylight (album) The title of a movie - Daylight (movie) The Southern Pacific railroad operated several named passenger trains named [adjective] Daylight (such as the Afternoon Daylight) in California. ... Night is the time when a location is facing away from the Sun, and thus dark. ... Crust composition Oxygen 43% Silicon 21% Aluminium 10% Calcium 9% Iron 9% Magnesium 5% Titanium 2% Nickel 0. ... Red is a color at the lowest frequencies of light discernible by the human eye. ...


It is important to emphasize that aerial perspective does not blur the outlines or the markings of objects. Objects appear less distinct because of the reduction in contrast. To illustrate that the air does not blur objects, one can look at the edge of the moon when it is on the horizon. Despite the light path being the longest possible through the atmosphere, the edge of the moon looks sharp. Cover of Blur: The Best Of - Clockwise from top left: Coxon, James, Rowntree, Albarn Blur is the name of a British rock band. ...


In art, aerial perspective was originally used in describing paintings where the impression of depth in a landscape is created by painting distant parts of the landscape as less detailed and as more blue. This use of pale colors and less pronounced tones suggests farther distances.

Basic Photography Techniques - Perspective. (1422 words)
In other words, perspective in the composition of a photograph is the way real three-dimensional objects are pictured in a photograph that has a two-dimensional plane.
When you know the principles of perspective and skillfully apply them, the photographs you produce show a good rendition of the subject's form and shape, and the viewer is given the sensation of volume, space, depth, and distance.
The other false perspective is produced by a fisheye lens in which all straight lines in the subject are imaged as curved lines toward the edges of the picture.
perspective: Definition, Synonyms and Much More From Answers.com (988 words)
Perspective is the choice of a single point of view from which to sense, categorize, measure or codify experience, typically for comparing with another.
Perspective as graphic representation of objects perceived by the eye denotes a technique of representing three-dimensional objects on a planar surface with the aim of retaining the illusion of three-dimensional space.
Perspective can be drawn in an instinctive way (as in the visual fine arts such as painting, sketching, etching, etc.) as well as in a quantified, technical way (technical graphics using drafting instruments).
