occurs when a gradual or smooth tonal transition in an image appears or is made to appear as an abrupt change from one tone to another. Digitally, it can be achieved by limiting the number of colors in an image so that the change from one tone to another is sudden, rather than continuous and gradual. Posterization can be noticed, for example, in an image that has a relatively large area of color that appears banded where the tonal changes should instead appear to be gradual.
A photographic or digital graphic effect arising from reducing the number of continuous tones in an image. Can be a deliberate effect or a result of over-manipulation or compression in a digital image.
The display of "bands" of color rather than a true gradient. Sometimes called "false contouring" it is typical a function of inadequate contrast ratio. Makes colored gradients appear as a series of "rings", with large changes in color between the rings as opposed to gradual, "gradient" changes.
A digital video effect that reduces the number of colors used to represent the image on screen, the simplest way being to reduce the number of bits used to represent the chrominance and luminance data (for instance from eight to four).
BANDING in a graphic or photographic image, caused by a limitation in the number of colors which can be reproduced in the image, or by excessive tonal corrections or manipulations of the image.
A method of replacing continuous tones with a limited number of flat tones, by making a line shot instead of a halftone; also called Photoposterization. to top
An effect that is achieved by converting an image with continuous tonal range (such as a photo) to one with a limited number of visible steps/bands.
Special effect in which the picture is reduced to a small number of chrominance or luminance levels by removing any fine gradations of color and brightness, resulting in an oil painting effect.
See Brightness Contouring.
A banding effect produced by reducing the number of gray tones in an image.
The conversion of continuous tone data into a series of visible tonal steps or bands.
Flattening of an image due to color blockage.
The conversion or reproduction of a continuous tone image to one with only a few distinct tones, or having a flat, poster-like quality.
the effect produced when a photographic image is displayed or printed with too few colors or shades of gray; the opposite of continuous-tone.
The visible banding in an image due to the lack of smooth gradations between tones.
A special effects printing technique that separates normal tones into distinct tone ranges by the use of high contrast films. A specialized darkroom technique.
The visible banding effect when a photographic image is displayed due to the lack of colors or shades of gray in a picture.
For a halftone, the reduction of the number of gray scales to produce a high-contrast image. See Gray-scale image, Halftone.
The effect produced when a photographic image is displayed or printed with a small number of colors or shades of gray.
Process of reducing the number of colors in an image. Used to aid in speeding the RIP process for solid-color images, it can greatly affect specific color integrity.
Banding or lack of continuous tones in an image. Can be a deliberate effect or, more commonly, a result of over-manipulation or compression in a digital image.
A special effect created by using a limited number of gray levels within an image. In computers it is created by setting a defined number of gradient steps in a bitmapped image.
A design developed in a manner or style characteristic of pictorial art posters. All color elements are flat-toned, but arranged in a way that gives main illustration / product a three dimensional effect, with bold contrasts.
photographic technique using a number of tone separated negatives which are printed on high contrast material. A master negative is made by printing these in register. The final print from this contains selected areas of flat tone in place of continuous tone. Sometimes incorrectly referred to as solarization.
Posterization of a photographic image being developed occurs when a region of an image with a continuous gradation of tone is replaced with several regions of fewer tones, resulting in an abrupt change from one tone to another. This creates an effect somewhat similar to that of a simple graphic poster. The effect may be created deliberately, or happen accidentally.
