The maximum contrast of an image is termed the contrast ratio or dynamic range. In images where the contrast ratio approaches the maximum possible for the medium, there is a conservation of contrast. In such cases, increasing contrast in certain parts of the image will necessarily result in a decrease in contrast elsewhere.
While it may occur naturally in any visual field, the term is most commonly used in design (especially graphic design and cartography), where elements are intentionally designed to make some look more important than others. This order is created by the visual contrast between forms in a field of perception. Objects with highest contrast to ...
The "luminance contrast" is the ratio between the higher luminance, L H, and the lower luminance, L L, that define the feature to be detected.This ratio, often called contrast ratio, CR, (actually being a luminance ratio), is often used for high luminances and for specification of the contrast of electronic visual display devices.
The visual weight in an image is defined as the visual force that appears due to the contrast of light among the visual elements that compound it. [1]The visual weight is a visual force which prevails in the image balance.
An LCD technology is dynamic contrast (DC), also called advanced contrast ratio (ACR), and smart contrast ratio (SCR [4]) and various other designations.When there is a need to display a dark image, a display that supports dynamic contrast underpowers the backlight lamp (or decreases the aperture of the projector's lens using an iris), but proportionately amplifies the transmission through the ...
Colors also have value; for example, yellow has a high value while blue and red have a low value. If you take a black and white picture of a colorful scene, all you are left with are the values. This important element of design, especially in painting and drawing, allows the artist to create the illusion of light through value contrast. [6]
Color theory has described perceptual and psychological effects to this contrast. Warm colors are said to advance or appear more active in a painting, while cool colors tend to recede; used in interior design or fashion, warm colors are said to arouse or stimulate the viewer, while cool colors calm and relax.
