It also allows for "Sparse Images"; where some parts of the image have greater resolution than others, an example of which can be found on the Seadragon Ajax home page; The bike image displayed is a sparse image. Though used in the proprietary Deep Zoom, the dzi format is open and able to be used by anyone. Deep Zoom image (dzi)
Digital zoom has been used to create the middle photo from within the top photo. The image quality has been lost. No quality is lost however, with the lens zoomed-in optically for the bottom photo. Typically, the digital zoom is not available until the optical zoom has been exhausted. Digital zoom is a method of decreasing the precise angle of ...
A zoom lens is a system of camera lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens ( prime lens ). A true zoom lens or optical zoom lens is a type of parfocal lens, one that maintains focus when its focal length changes. [1] Most consumer zoom lenses do not maintain ...
For real images, such as images projected on a screen, size means a linear dimension (measured, for example, in millimeters or inches). Angular magnification [ edit ] For optical instruments with an eyepiece , the linear dimension of the image seen in the eyepiece ( virtual image at infinite distance) cannot be given, thus size means the angle ...
Ken Burns effect. The Ken Burns effect is a type of panning and zooming effect used in film and video production from non-consecutive still images. The name derives from extensive use of the technique by American documentarian Ken Burns. This technique had also been used to produce animatics, simple animated mockups used to previsualize motion ...
Whip zoom An unusually quick but continuous zoom in or out. Wipe An optical editorial transition in which an image appears to be pushed or "wiped" to one aside of the screen to make way for the next. Zoom A shot taken from a stationary position using a special zoom lens that magnifies or de-magnifies the center of the image. This creates an ...
In photography and cinematography, a wide-angle lens is a lens covering a large angle of view. [a] Conversely, its focal length is substantially smaller than that of a normal lens for a given film plane. This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior, and landscape ...
The Droste effect ( Dutch pronunciation: [ˈdrɔstə] ), known in art as an example of mise en abyme, is the effect of a picture recursively appearing within itself, in a place where a similar picture would realistically be expected to appear. This produces a loop which in theory could go on forever, but in practice only continues as far as the ...
