Thus, during the zoom, there is a continuous perspective distortion, the most directly noticeable feature being that the background appears to change size relative to the subject. Hence, the dolly zoom effect can be broken down into three main components: the moving direction of the camera, the dolly speed, and the camera lens' focal length.

Not only do animated images form part of computer-generated imagery; natural looking landscapes (such as fractal landscapes) are also generated via computer algorithms. A simple way to generate fractal surfaces is to use an extension of the triangular mesh method, relying on the construction of some special case of a de Rham curve , e.g ...
For display on the computer, techniques like animated GIF and Flash animation were developed. Composite of photos of one place, made more than a century apart 3D modeling : In 3D computer graphics , 3-D modeling is the process of developing a mathematical representation of any surface of an object (either inanimate or living) in three ...
The effect can be used as a transition between clips as well. For example, to segue from one person in the story to another, a clip might open with a close-up of one person in a photo, then zoom out so that another person in the photo becomes visible. The zooming and panning across photographs gives the feeling of motion, and keeps the viewer ...
Statistically, images have more low-frequency than high-frequency content, so it is the low-frequency content that remains after quantization, which results in blurry, low-resolution blocks. In the most extreme case only the DC-coefficient, that is the coefficient which represents the average color of a block, is retained, and the transform ...
