brightness

Definition of brightness in English English dictionary: the quality of being bright; the perception elicited by the luminance of an object; intelligence, cleverness; {n} luster, splendor, acuteness; The brightness of an extended luminous source is termed the intensity per unit area measured in candles per cm2 Also, the intensity of reflection; it may be measured in lamberts; one lambert equals 1 lumen/cm2; the perceived amount of light in a scene, corresponding roughly to the level of physical illumination See also surface lightness; A measure of the light received from an object, adjusted for the wavelength; The reflectance or brilliance of the paper when measured under a specially calibrated blue light Not necessarily related to color or whiteness Brightness is expressed in %; Also called value, one of the three attributes of color (the other two are hue and saturation) Brightness describes differences in the amount of light reflected from or transmitted through an image regardless of its hue and saturation This is a difficult word to use in making color correction; it is used to indicate both the addition and subtraction of color Correctly used, it refers to the amount of light (paper white) apparent in an area In terms of paper, brightness is the light reflectance or brilliance of the paper at a specific wavelength, often perceived as whiteness Generally, the higher the brightness rating, the better quality the paper; The attribute of visual perception in accordance with which an area appears to emit or reflect more or less light (this attribute of color is used in the color model HSB - Hue, Saturation, Brightness) See Lightness; Strictly speaking, a subjective impression of the lightness of an object The correct term for the measurable quantity of light reflected or produced by an object is luminance See also luminance; the location of a visual perception along the black-to-white continuum; The overall intensity of the image The lower the brightness value, the darker the image; the higher the value, the lighter the image will be; Brightness is the lightness or darkness of the colour, how close it is to either black or white You can control the brightness of a base colour by adding white or black, but this will lower the saturation With some colours you will need to compensate by adding another colour, such as yellow or a more saturated paint than that used for the base colour; Measurement of the reflective quality of a medium Different brightness levels can cause changes in the appearance of colors on the medium, requiring adjustments in calibration to achieve optimum results; - The degree of light reflected from the surface Measured by a reflectance meter; The value of a pixel in an electronic image, representing its lightness value from black to white Usually defined as brightness levels ranging in value from 0 (black) to 255 (white); The brightness of a surface is measured in the candles per unit area It equals the product of the illumination per unit area and the reflectivity of the surface (reflection factor) divided by pi It is also measured in lamberts; 1 lambert is the equivalent of 1 lumen per square centimeter; The quality or state of being bright; splendor; luster; brilliancy; clearness; Acuteness (of the faculties); sharpness 9wit; Brightness is an optical quality of paper based on reflection of light from its surface Brightness is the percentage of incident light reflected from paper when the light source is at a 45 degree angle to the paper and the measuring device at a 90 degree angle The brightness of white and near-white papers can be considered as the whiteness of the paper as it appears to the eye Brightness affects the contrast, color values, and attractive appearance of a printed product; One of three dimensions of color; the other two are hue and saturation The term is used to describe differences in the intensity of light reflected from or transmitted through an image independent of its hue and saturation; Both the saturation and lightness of product color; Changing the Brightness makes the whole image lighter or darker; intelligence as manifested in being quick and witty; The luminance of objects The brightness of any area of the subject is dependent on how much light falls on it and how reflective it is Brightness range is the relationship we perceive between the light and dark subjects in a scene Brightness contrast is a judgment of the relative measure of that range, such as high, low, or normal Brightness values are sometimes referred to as EV (exposure values), a combination of aperture and shutter speed Brightness values in the scene are translated to tonal values on film; {i} luminosity; radiance; cheerfulness; intelligence, cleverness; clarity; The brightness of a light source is defined as the power emitted per unit surface area per unit solid angle; 1 The attribute of visual perception in accordance with which an area appears to emit more or less light; A measure of the overall intensity of the image The lower the brightness value, the darker the image; the higher the value, the lighter the image will be; the quality of being luminous; emitting or reflecting light; "its luminosity is measured relative to that of our sun"; – Brightness is a key indicator of paper quality It is measured by shining blue light on the paper, and finding out how much of the light is reflected; An attribute of visual perception in which a source appears to emit a given amount of light Note 1: "Brightness" should be used only for nonquantitative references to physiological sensations and perceptions of light Note 2: "Brightness" was formerly used as a synonym for the photometric term "luminance" and (incorrectly) for the radiometric term "radiance "; The difference in intensity of the light reflected from or transmitted by a color image The hue of an object may be blue, but dark and light distinguish the brightness of one object from another; The visual sensation of the luminous power of a light beam, as opposed to scientifically measured power of the beam; the location of a visual perception along the black-to-white continuum intelligence as manifested in being quick and witty; shiningness; {i} candescence
