The foreground is in focus, but slightly smudged; the middle ground has sharp, clear edges and well defined subjects, and the background fades into the distance, becoming more and more blurry the farther back the eye travels. He makes the middle ground section more clear, mimicking the effect of a camera.
In painting, photography, graphical perspective and descriptive geometry, a picture plane is an image plane located between the "eye point" (or oculus) and the object being viewed and is usually coextensive to the material surface of the work.
Mary Ellen Mark (March 20, 1940 – May 25, 2015) was an American photographer known for her photojournalism, documentary photography, portraiture, and advertising photography. She photographed people who were "away from mainstream society and toward its more interesting, often troubled fringes".
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]
A front projection effect is an in-camera visual effects process in film production for combining foreground performance with pre-filmed background footage. In contrast to rear projection, which projects footage onto a screen from behind the performers, front projection projects the pre-filmed material over the performers and onto a highly reflective background surface.
Linear or point-projection perspective works by putting an imaginary flat plane that is close to an object under observation and directly facing an observer's eyes (i.e., the observer is on a normal, or perpendicular line to the plane).
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.
