A full screen effect (sometimes written as fullscreen effect) is any graphics technique that is applied to the entire screen, usually after the rest of the image has been rendered. This is in contrast to effects that are applied to each element of an image—such as a three-dimensional triangle—as it is drawn. The speed of applying a full screen effect is independent of the complexity of the image.
In 3D rendering applications such as video games, common full screen effects include
color filter
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associa ...

depth of field
The depth of field (DOF) is the distance between the nearest and the furthest objects that are in acceptably sharp focus in an image captured with a camera.

full screen bloom. A color filter, for example, may desaturate an image or convert it to grayscale. These effects are usually achieved via

shader
In computer graphics, a shader is a computer program that calculates the appropriate levels of light, darkness, and color during the rendering of a 3D scene - a process known as ''shading''. Shaders have evolved to perform a variety of spec ...
