Backgrounds can be entirely neutral, like a solid backdrop or a cloudless sky; or they can complement the image, like a starfish on the sand. A more technical method of achieving simplicity involves focusing on the subject while ensuring the background is out of focus.
From left to right: an original photo with no bokeh or blur; the same photo with synthetic bokeh effect applied to its background; the same photo with Gaussian blur applied to its background. Bokeh can be simulated by convolving the image with a kernel that corresponds to the image of an out-of-focus point source taken with a real camera.

Other hues besides grey can be used to create monochrome photography, [1] but brown and sepia tones are the result of older processes like the albumen print, and cyan tones are the product of cyanotype prints.
Chroma key is achieved by comparing the phase of the video to the phase corresponding to the pre-selected colour. In-phase portions of the video are replaced by the alternate background video. [citation needed] In digital colour TV, colour is represented by three numbers (red, green, blue intensity levels). Chroma key is achieved by a simple ...
A photograph of a neighborhood watch sign is the foreground color while the rest of the image is the background color. [1] In the document-scanning industry, this is often referred to as "bi-tonal". A binary image is a digital image that consists of pixels that can have one of exactly two colors, usually black and white.

The project was produced at Bent Image Lab in July 2006 and directed by filmmaker Chel White. In this instance, the false diorama effect was achieved digitally ...
