- Яркость
- The clarity, strength, and brightness of a color or varnish.
- The intensity of the white light perceived by the eye when viewing a diamond’s crown, including from external and internal reflections. clarity, polish, proportions, symmetry, and the quality of workmanship are factors that contribute to a diamond’s brilliance.
- Intensity of the internal and external reflections of white light from the crown of a polished diamond or other gemstone. hardness, refractive index, reflectivity, polish, lustre and proportions all affect a gemstone`s brilliance.
- Diamond brilliance is comprised of two components brightness and contrast. it is the sparkle you see when light is reflected from the surface as well as the total internal reflection of light.

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.
- Яркость. для видеосигналов систем ntsc и pal
Reflections, английский
Out-of-control reflections can hurt your image; controlled ones can enrich it. tips: keep the subject in full sun, the reflecting surface, such as water, in shade. reflections on water are most pronounced when the lens is at a low angle. most mirrors add a greenish cast to the image. normal mirrors add a "ghost reflection" to the main reflection; use a first surface mirror for critical images.
Proportions, английский
- Пропорции
- Relative dimensions and angles of a polished diamond and the relationships between them; these include table size, crown angle, crown height, girdle thickness, pavilion angle, pavilion depth, culet size, girdle outline, length-to-width ratio, and total depth.
Workmanship, английский

Содействовать; способствовать; сотрудничать
Refractive, английский
Reflectivity, английский
- A measure of the fraction of incident radiation falling on a surface that is turned back from it by reflection. reflectivity also refers to the degree by which precipitation is able to reflect a radar beam.
- Отражательная способность
- Коэффициент отражения, отражательная способность
- Ability of a surface to reflect electromagnetic radiation, expressed as ratio r of the intensity of the total energy reflected from a surface to total radiation on that surface. for a perfect mirror, reflectivity r approaches 1.0; for a blackbody, the reflectivity is zero.
- Ability of a surface to reflect radiation, expressed as the ratio ? of the intensity of the total energy reflected from a surface to total radiation on that surface. for a perfect mirror, reflectivity r approaches 1.0; for a blackbody the reflectivity is 0. compare reflectance; reflection.

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.

Brit, английский
- British
- Not just a statement of nationality, but a general description of small fry destined to be pillaged by bass and mackerel around the uk during the summer months.
- Не просто заявление о национальности, а общее описание мелкой рыбешки, которой суждено быть разграбленной окунем и скумбрией по всей великобритании в летние месяцы.
