Foreground-background, a scheduling algorithm that is used to control execution of multiple processes on a single processor; Foreground-background segmentation, a method for studying change blindness using photographs with distinct foreground and background scenery; Foreground detection, a concept in computer vision to detect changes in image ...
For example, the foreground might be in focus while the middle-ground and background are out-of-focus. When avoiding deep focus is used specifically for aesthetic effect—especially when the subject is in sharp focus while the background is noticeably out-of-focus—the technique is known as bokeh. [2]
In photography and cinematography, perspective distortion is a warping or transformation of an object and its surrounding area that differs significantly from what the object would look like with a normal focal length, due to the relative scale of nearby and distant features.
In Schenkerian analysis, a structural level is a representation of a piece of music at a different level of abstraction, with levels typically including foreground, middleground, and background. [1] According to Schenker musical form is "an energy transformation, as a transformation of the forces that flow from background to foreground through ...
Consequently, the foreground and background are often blurred, with the blur increasing with distance above or below the center of the image. In a photograph of a full-size scene, the DoF is considerably greater; in some cases, it is difficult to have much of the scene outside the DoF, even at the lens's maximum aperture. Thus a difference in ...
Layering is a photographic composition technique that manipulates the foreground, subject or middle-ground, and background layers in a way that they all work together to tell a story through the image. [52] Layers may be incorporated by altering the focal length, distorting the perspective by positioning the camera in a certain spot. [53]
Mattes are used in photography and special effects filmmaking to combine two or more image elements into a single, final image. Usually, mattes are used to combine a foreground image (e.g. actors on a set) with a background image (e.g. a scenic vista or a starfield with planets). In this case, the matte is the background painting.
The photograph demonstrates the application of the rule of thirds. The horizon in the photograph is on the horizontal line dividing the lower third of the photo from the upper two-thirds.
