Black and white (b&w)
| Light Glossary |
B&w film offers opportunities and challenges. foreground and background may merge in the absence of color separation. tips: use more back light or background light. view the scene with a b&w viewing glass. other differences: color temperature complications disappear and all those long-abandoned filters that turn blue skies black and trees white can be used again. last tip: while many of the black and white masters aren`t around, their masterpieces are. quote: the most difficult task for today`s director of photography is to "think" in black and white again. he must become mentally color-blind, imagining what each scene will look like on the screen when it loses the colors it has in reality. - nestor almendros [amwac]

Opportunities, английский
In general: conditions that allow for advancement, progress or profi t. in the policy context, circumstances for action with the attribute of a chance character. for example, the anticipation of additional benefi ts that may go along with the deployment of renewable energy (enhanced energy access and energy security, reduced local air pollution) but are not intentionally targeted. see also co-benefi ts and drivers.
Foreground, английский
- Dark foregrounds help hold the eye within the frame and increase the illusion of depth. bright foreground objects, especially out-of-focus or moving ones, can be distracting. tip: back or side-light the foreground using little or no fill. also see: frame.
- The brush color of displayed characters and graphics, for example, the color of the text that is displayed in a textbox control.
Background, английский
- Фон
- The surface area against which the pattern is contrasted. the surface area of
- The portion of a scene that sits behind the main, foreground subject. the background can be made sharp or unsharp through the use of selective focusing techniques and depth of field manipulation.
- A фоновый; внеязыко- вой knowledge
- Sound or noise that interferes with radio or sonar reception.
- Фон, задний план о ~ for
- A page that you can assign to another page to create multiple layers in a drawing.
- In a graphical user interface such as windows, a pattern or picture in the screen background that can be chosen by the user.
- The area on a card that allows a user to make the card’s image a background when clicked on.
- The area that appears behind the tiles on the start screen.
- The color or image that appears behind the content of a visual element, for example, behind the text that is displayed in a textbox control or on your graphical user interface.
- The image that appears in the conversation window.
- The picture that appears in the photos hub.
- Formations on or signals from a test object that constitute the background to a discontinuity. the higher the level of background noise, the more difficult it is to distinguish a discontinuity. background signals may arise from visual, acoustic, chemical, electrical, or radiation sources that the sensor responds to. see also sensitivity; signal-to-noise ratio.
- Formations on or signals from a test object that constitutes the background to a discontinuity. the higher the level of background noise, the more difficult it is to distinguish a discontinuity. background signals may arise from visual, acoustic, chemical, electrical or radiation sources that the sensor responds to. see also neural acuity; sensitivity; signal-to-noise ratio.
- Formations on, or signals from, a test object that constitute the background to a discontinuity. the higher the level of background noise, the more difficult it is to distinguish a discontinuity. see also background fluorescence; neural acuity; sensitivity; signal-to-noise ratio. glossary b 491
- In magnetic particle testing, the appearance or brightness of the surrounding area acting to reduce the contrast of an indication. (2) nonrelevant signal that tends to interfere with the normal reception or interpretation of the target being sought.
Separation, английский
- Разделение, отделение; эшелонирование; интервал эшелонирования
- Отделение, разделение; эшелонирование; интервал эшелонирования
- The development of layers of paint of different composition in a can during storage when the materials are not completely soluble, miscible, or stable.
- The act of separating or dividing two or more people or things, or the state of being separated
- Супругов, судебное разлучение
Differences, английский
Цифровой избирательный вызов, цив - технология радиосвязи, при которой предварительное согласование канала вызова другого судна осуществляется не широковещательно на голосовом канале, а на отдельном цифровом канале. после согласования рабочего канал
Temperature, английский
- Température
- Dry-bulb - temperature of air as indicated by a standard thermometer.
- An expression of thermal energy density. how hot or cold an object is.
- The measure of the intensity of heat that a substance possesses.
- Температура
- Температура тмр test methods and procedures методы проведения испытаний и последовательность их проведения тмр theodolite measuring point кинотеодолитная станция
- Temperatura, fiebre
- The condition attained when the wetted wick of a wet-bulb thermometer has reached a stable and constant temperature when exposed to moving air in excess of 900 ft (274.3 m) per minute.
- 1. the heat of the body or of the surrounding air, measured in degrees the doctor asked the nurse what the patient’s temperature was. his temperature was slightly above normal. the thermometer showed a temperature of 99°f. to take a patient’s temperature to insert a thermometer in someone’s body to see what his or her body temperature is they took his temperature every four hours. when her temperature was taken this morning, it was normal. 2. illness when your body is hotter than normal he’s in bed with a temperature. her mother says she’s got a temperature, and can’t come to work. comment: the average body temperature is about 37° celsius or 98° fahrenheit. this temperature may vary during the day, and can rise if a person has taken a hot bath or had a hot drink. if the environmental temperature is high, the body has to sweat to reduce the heat gained from the air around it. if the outside temperature is low, the body shivers, because rapid movement of the muscles generates heat. a fever will cause the body temperature to rise sharply, to 40°c (103°f) or more. hypothermia exists when the body temperature falls below about 35°c (95°f).
- Повышение температуры бетона ~ of truss высота фермы jet ~ высота подъёма горизонтальной неизотермической приточной струи, «всплывающей» над приточным отверстием
- Температура ~ of adiabatic saturation температура адиабатического насыщения
- Normal adult temperature varies among horses, but will usually range in degrees from 99.5°f to 100.5°f.
- A measure of the average kinetic energy of a material. the standard unit of temperature is a kelvin, (k). temperature determines the direction of heat flow between any two systems in thermal contact. heat will always flow from the area of higher temperature (t source) to one of lower temperature (t sink). temperature gradient (?t)
- A measure of the degree of molecular motion of a material compared to a reference point. temperature is measured in degrees farenheit (melting point of ice = 32 º f, boiling point of water = 212 º f) or degrees celsius (melting point of ice = 0 º c, boiling point of water = 100 º c).
- The degree of sensible heat of a body as measured by a thermometer or similar instrument.
- Measure of the intensity of particle motion in degrees celsius (°c) or degrees fahrenheit (°f) or, in the absolute scale, kelvin (k), where the increment of 1 k = 1 °c = 1.8 °f.
- Temperature of surrounding atmosphere. also called dry bulb temperature. compare standard atmospheric conditions. ampere (a): si unit of electric current. ampere per meter (a·m–1): si derived unit of magnetic field intensity. the measurement 1 a·m–1, for example, describes a current of 1 a flowing through a coil that is 1 m in diameter. compare oersted. ampere turn (at): in magnetic particle testing, unit for expressing the magnetomotive force required for magnetization using a coil in terms of the product of the number of coil turns and the current in amperes flowing through the coil. amplitude, echo: in ultrasonic testing, the vertical height of a received signal on an a-scan, measured from base to peak for a video presentation or from peak to peak for a radio frequency presentation.
- Measure of the intensity of particle motion in degrees celsius (°c), degrees fahrenheit (°f) or, in the absolute scale, kelvin (k) or degrees rankine (°r). an increment of 1 k = 1 °c = 1.8 °r = 1.8 °f. compare heat.

Photography, английский
- Technique of producing permanent images on sensitized surfaces by means of the photochemical action of light or other forms of radiant energy.
- Writing with light.
- The word photography comes from two old greek words “phos” meaning light and “graph” meaning to draw. so photograph literally means to draw with light, or a drawing made with light. so photography is the art of drawing with light.
- The act of taking pictures with a camera the development of x-ray photography has meant that internal disorders can be more easily diagnosed.
- Фотосъёмка, фотография

B lights, the two bs, английский
Back light and background light are frequently confused. both begin with "back," both are used to separate planes and imply depth, and both are tricky to motivate so that they appear realistic. each, however, points in a different direction. tip: discretion may dictate that only one or, on occasion, neither is really needed.to paraphrase shakespeare, in a rather different context: two b or not two b, that is the question.
Upstage, английский
- Away from the audience or camera.
- The back part of a stage, away from the audience.
