Polarizer. (polarising filter)
| Глоссарий по фотографии |
A filter for eliminating glare and reflections which attached to the front of your lens (normally just slr’s). just like your polarized sunglasses it will get rid of glare, the polarizer filter does the same for your digicam. there are 2 types of polarising filter, linear and circular. linear is for film only, it screws up most auto focus systems on digicams. therefore be sure you use a circular polarizer filter. it can also be used to darken skies and increase the saturation of colours.

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.
Saturation, английский
- The condition when the partial pressure of water vapour in the atmosphere is at its maximum level for the existing temperature and pressure. for example, at saturation an equilibrium exists between water vapour and liquid water and there is no net evaporation or condensation.
- The attribute of color perception that expresses the amount of departure from the neutral gray of the same lightness. also referred to as chroma.
- Насыщенность
- Насыщенность (цвета). показатель, описывающий силу цвета и его уровень серого. мера чистоты цвета, определяющая количество содержащегося в нем серого. чем выше содержание серого, тем ниже насыщенность цвета
- In color, the degree to which a color is diluted with white light or is pure. the vividness of a color, described by such terms as bright, deep, pastel, pale, etc. saturation is directly related to the amplitude of the chrominance signal.
- Насыщение
- The degree to which a color is undiluted by white light. if a color is 100 percent saturated, it contains no white light. if a color has no saturation, it is a shade of gray.
- The degree of intensity of a hue. also, the result of hanging a hot light under an automatic sprinkler head.
- Saturation is the depth of the colors within a photographic image. photographs with deep levels of color are described as being heavily saturated. a photograph with lighter levels of saturation is described as having a muted color palette. a totally desaturated color photograph becomes monotone—or black and white.
- 1) in a communications system, the condition in which a component of the system has reached its maximum traffic handling capacity. 2) the point at which the output of a linear device, such as a linear amplifier, deviates significantly from being a linear function of the input when the input signal is increased. 3) the degree of the chroma or purity of a color.
- In color, a vividness, or intensity. some films have more inherent color saturation than others. saturation can be slightly increased by moderate film pushes, or by slight underexposure of certain slide films. saturation can be increased in color negative film by moderate overexposure.
- The degree to which a colour is undiluted by white light. if a colour is 100 percent saturated, it contains no white light. if a colour has no saturation, it is a shade of grey.
- A most important aspect in producing high quality leathers. full saturation of tanning, fat liquors and dyes are essential in the production of fine leathers. self-covered seat deck: in upholstered furniture, using cover fabric to cover area under loose cushions. also called self-covered deck. selvage: tightly woven edges that prevent fabric from fraying on the roll. the selvage must be cut away for many fabrics to drape smoothly. serpentine form: profile made up of convex curve flanked by two concave curves.
- N насыщение; запол- нение актантных позиций saussurean a соссюрианский
- Насыщение-отбора проб. обычно, особенно в сша, так называется прибор, в котором имеются таймер (регулятор выдержки времени), коллектор и 6 или более клапанов с проходным отверстием для подачи воздуха в различные устройства для забора проб через заданные интервалы времени. этот термин относится также к автоматическому устройству для ежечасных: замеров концентрации дыма. воздух пропускается при постоянной скорости через бумажный фильтр, на котором после этого остается темное пятно дымовых частиц. фильтровальная бумага (в виде свернутой в трубочку полоски шириной: 20—30 мм) проходит через зажим фильтра, закрепленный пружинами для обеспечения герметичности. в конце каждого-часа зажим открывается и полоска бумаги продвигается вперед на 40—50 мм, после чего зажим опять защелкивается. в результате на бумаге образуется ряд пятен, каждый час-по одному пятну. термин «последовательный пробоотборник» иногда применяется также для обозначения полуавтоматического прибора (см. semi-automatic apparatus).
- Overload of a magnetic tape. the saturation point is the point at which an increase in magnetizing force does not cause a corresponding increase in magnetization of the tape oxide particles.
- In color management, the purity of a color’s hue, moving from gray to the pure color. save (v)
- 1. the maximum intensity or purity of a color. if the color is as brilliant as possible, it is at saturation; if the color is subdued or grayed, it is dull, weak, and low in intensity. 2. the upper limit concentration of a solute in a solvent, i.e., no more solute can be dissolved at a fixed temperature and pressure.
- The intensity or purity of a hue; the color of the greatest purity are those in the spectrum. words used to describe saturation are vivid, dull, brilliant, dark, deep, light, medium, pale, and weak.
- Condition in which high amplitude signals on a display screen do not increase with increased gain and appear flattened.
- Relative or comparative color characteristic resulting from a hue’s dilution with white light.
- (1) in nondestructive testing, signal amplitude at or above sensor’s maximum capability. (2) relative or comparative color characteristic resulting from a hue’s dilution with white light.
- Magnetic saturation.
- Condition in which high amplitude signals on a display screen do not increase with increased gain and appear flattened.7

Under exposure, английский
A picture which appears too dark because insufficient light was delivered to the imaging system. opposite of over exposure.
Colour correction, английский
To correct or enhance the colours within an image.
