Glare, английский
- Блик. очень яркое отражение света на экране дисплея
- Ground level
- Блик
- Random illumination incident on the image plane that is not associated with the primary image.
- Light reflected toward the camera from shiny or even relatively matte surfaces. in moderation, it is one of the most useful ways to add life to drab subjects. if excessive, tame it by: moving the glaring object, the light, or camera angle; using softer light, a polarizing camera filter (not on bare metal), or dulling-type spray (not on bald heads). also see: kicks and . . .
- 1. a long stare that expresses a negative emotion such as anger 2. an uncomfortably or dazzlingly bright light 3. scattered bright light when examining something with a microscope verb 1. to stare angrily 2. to shine uncomfortably brightly 3. to be very obvious or conspicuous
- Relatively bright light entering the eye creating dazzle, discomfort, or visual impairment.
- The sensation produced by brightnesses within the visual field that are sufficiently greater than the luminance to which the eyes are adapted to cause annoyance, discomfort, or loss in visual performance and visibility.
- Слепящий свет
- Sound which is too bright, trebly or edgy.
- Excessive brightness (or brightness varying by more than 10:1 within the field of view) that interferes with observation or interpretation of a test response. glare may be caused by reflection, whether specular (smooth surface) or diffuse (rough surface), of light or radiation sources. glare, blinding: glare so intense that for an appreciable length of time after it has been removed, no object can be seen.2,6 glare, direct: glare resulting from high luminances or insufficiently shielded light sources in the field of view. direct glare is usually associated with bright areas, such as luminaires, ceilings and windows which are outside the visual task or region being viewed.2,6 glare, reflected: glare resulting from specular reflections of high luminances in polished or glossy surfaces in the field of view. it usually is associated with reflections from within a visual task or nearby areas.2,6
- Excessive brightness (or brightness varying by more than 10:1 within the field of view) that interferes with observation or interpretation of a test response. depending on intensity, glare may be blinding or merely discomforting. often caused by reflection, whether specular (from a smooth surface) or diffuse (from a rough surface), of light or radiation sources.
- Excessive brightness (or brightness varying by more than 10:1 within the field of view) that interferes with observation or interpretation of a test response. glare may be caused by reflection, whether specular (smooth surface) or diffuse (rough surface), of light or radiation sources.
Glare, английский
Glare angle, angle of reflection, английский
The law-of-the-light states: "the angle of reflection is equal to the angle of incidence." simply: light is reflected at the same angle it came from, but in the opposite direction. pool players understand. tip: as soon as this law becomes intuitive, lighting will be easier.
Glare zone, английский
The angle within which lights will produce glare on a surface; beyond which, the glare-free zone*, it will be absent. see: glare and copy art.
Glarea, ae, f, латинский

Reflect, английский
- A gradient brush option that makes the gradient repeat in alternating reflections.
- To copy driver binaries, install services, and add registry keys for one or more drivers from a driver package onto a system, without the context of a specific device. a system can be booted from reflected drivers, however full device installation may still be required in order to enable full driver functionality.
Reflect prevention sheet, английский
Reflectance, английский
- The percentage of light that is reflected from an object. spectrophotometers measure an object's reflectance at various intervals along the visible spectrum to determine the object color's spectral curve. see spectral curve, spectral data.
- The ratio of light returned from a surface expressed as a percentage.
- Отражательная способность
- The percentage of light reflected from a component, such as a connector, splice, splitter, or wdm
- The ratio of the reflected flux to the flux incident on a surface. reflectance coefficient, reflectance factor
- Коэффициент отражения, отражательная способность
- Ratio of reflected wave energy to incident wave energy. also known as reflectivity.
Reflectance (or reflection factor), английский
Отражательная способность (или коэффициент отражения). отношение потока лучистой энергии (или света), отражаемой данной поверхностью, к потоку лучистой энергии (или света), падающему на эту поверхность.
Reflectance pattern, английский
A reflectance pattern is an observation whose attributes have been normalized so that their values add up to one. see also: ann, normalization.
Reflectance reflectivity, английский
The ratio of the reflected radiant power to the incident radiant power.
Reflectance. light-reflective glass, английский

Reflectancia del nivel de base ., испанский
Reflected, английский
Reflected light, английский
- Scene illumination multiplied by reflectance. this is the amount of light returned to the camera and determines the quality of picture.
- Various surfaces in a scene reflect between 1% and 95% of the incident light. specular surfaces will reflect it narrowly. diffuse (rough, irregular, or matte) surfaces scatter it. also see: glare and bounce light for further reflections.
Reflected light meter, английский
A meter that reads light reflected from the subject. all in-camera meters are of this type.
Reflected light meter (rlm), английский
An rlm reads light that is reflected from a scene. aim these meters at the subject or scene or a gray card from the direction of the camera. also see: spot meter and 18% assumption*.
Relatively, английский
Illuminated, английский
Reflection, английский
- The abrupt change in direction of a light beam at an interface between two dissimilar media that returns the beam into the medium where it originated, i.e., a mirror
- A light ray incident on an air to glass interface will have some of its energy redirected back toward its origin due to reflection at the interface.
- The return of radiant energy (incident light) by a surface, with no change in wavelength.
- The bouncing off of light which falls upon a surface.
- The change of direction which a ray of light, sound, or radiant heat undergoes when it strikes a surface; also
- 1. the image of somebody or something which is seen in a mirror or still water 2. the process of reflecting something, especially light, sound or heat 3. careful thought 4. a situation in which an anatomical structure bends back upon itself
- The process of obtaining information about assemblies and the types defined within them, and creating, invoking, and accessing type instances at run time.
- When light bounces back from a surface
- General term for the process by which the incident energy leaves a surface or medium from the incident side, without change in frequency. reflection is usually a combination of specular and diffuse reflection.2,6
- General term for the process by which the incident energy leaves a surface or medium from the incident side, without change in frequency. reflection is usually a combination of specular and diffuse reflection (iesna 1984). see also diffuse reflection; specular reflection.
- The act of thinking deeply about one`s actions, behaviour`s, and progress, often facilitated by a coach or mentor to promote self-awareness and learning.
Brightness, английский
- Term for the intensity of illumination of a reproduced video picture.
- 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.
- A term to indicate the relative amount of light intensity available. brighter is more light, dimmer is less light. in an infrared system, the brightness control may affect actual image intensity or it may change the temperature range displayed. either eff
- The attribute of visual perception in accordance with which an area appear to emit more of less light. (luminance is the recommended name for the photo-electric quantity which has also been called brightness.)
- In ntsc and pal video signals, the brightness information at any particular instant in
- Яркость
- 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).
- In ntsc and pal video signals, the brightness information at any particular instant in a picture is conveyed by the corresponding instantaneous dc level of active video. control is an adjustment of setup (black level, black reference).
- Is strictly defined as an attribute of a visual sensation according to which an area appears to emit more or less light. we sometimes misuse the term brightness in this catalog instead of the more correct “luminance.” luminance, used for sources, is the luminous flux in an elemental beam from a given point per unit area per solid angle in the specified direction.
- The visual sensation of the luminous intensity of a light source. the brightness of a laser beam is most closely associated with the radiometric concept of radiance.
- A term mostly used in a qualitative way, related to the output power and beam quality of a laser; quantitatively
- 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.
- Value of a pixel in a digital image giving its value of lightness from black to white, with o being black and 255 being white.
- That attribute of visual perception in accordance with which a surface appears to emit more light or less light. now called luminance.
- The amount of light that is emitted by a computer monitor or picture displayed on the monitor.
