Angle of view
|
- Represents the area of a scene (maximum horizontal and vertical angle) that can be seen through a lens. measured in degrees.
- Может быть выражена в диагонали, по горизонтали или по вертикали. меньшие фокусные растояния предоставляют более широкий угол обзора.
- May be expressed in diagonal, horizontal or vertical. smaller focal lengths give a wider angle of view.
- Угол обзора. может быть диагональным, вертикальным или горизонтальным . меньшее фокусное расстояние дает более широкий угол обзора.
- The angle of view is calculated by the focal length of the lens and the size of the image sensor. consumer digicam focal lengths are usually stated in terms of their 35mm film equivalents. for digital slr cameras with interchangeable lenses it`s more difficult as different cameras have different size sensors. use this online lens calculator to view the angle of view of a lens on any of today`s popular dslr cameras.
- The angle accepted by a lens or meter which depends upon its focal length and the camera aperture (commonly, the horizontal angle). answer print, trial print (film) one of the early lab attempts (typically there are two or three) to combine picture and sound. it is also the time for light and color correction and exploration; the time when all your previous efforts can be spoiled or perfected. be there. see: timed print (an earlier stage).
- The maximum angle a lens covers in the field. measured in degrees, and qualified by terms such as wide-angle, normal, and telephoto. a wide angle lens has a wider angle of view than a telephoto lens. a 135mm lens on a 35mm slr covers an 18-degree angle of view; a 28mm lens covers a 75-degree angle of view.
- This is calculated by the focal length of the lens and the size of the image sensor. the 35mm equivalents differ according to the sensor size.
- Угол обзора.
- In visual testing, the angle in degrees between the field of view axis and the axis of the fiberscope’s articulating section. also called direction of view angstrom (a): disused unit of length. 1 a = 0.1 nm.

- Угол
- The space or aperture intersected by the natural inclination of two lines or planes meeting each other, the place of intersection being called the vertex or angular point, and the lines legs. angles are distinguished by the number of degrees they subtend, to 360°, or the whole circumference of a circle. angles are acute, obtuse, right, curvilinear, rectilinear, &c. (all of which see).

- At right angles to the direction of gravity; on the level; parallel to the horizon; neither vertical nor inclined.
- A direction parallel to the horizon, or what is commonly termed lying flat. one of the greatest inconveniences navigators have to struggle with is the frequent want of a distinct sight of the horizon. to obviate this a horizontal spinning speculum was adopted by mr. lerson, who was lost in the victory man-of-war, in which ship he was sent out to make trial of his instrument. this was afterwards improved by smeaton, and consists of a well-polished metal speculum about 3-1/2 inches in diameter, inclosed within a circular rim of brass, so fitted that the centre of gravity of the whole shall fall near the point on which it spins. this is the end of a steel axis running through the centre of the speculum, above which it finishes in a square for the convenience of fitting a

Aperture, английский
- The light gathering part of a lens. the size of the aperture is controlled by the iris. aperture size is expressed as an "f" number. the lower the "f" number the greater the amount of light gathered by the lens.
- Апертура, диаметр отверстия объектива
- Открытие объектива, которая контролирует количество света, достигающее поверхности матрици устройства. размер апертуры контролируется регулировкой диафрагмы.
- In television optics, it is the effective diameter of the lens that controls the amount of light reaching the photoconductive or photo emitting image pickup sensor.
- The opening of the lens that controls the amount of light reaching the surface of the pickup device. the size of the aperture is controlled by the iris adjustment.
- The opening of a lens that controls the amount of light reaching the surface of the
- The lens opening formed by the iris diaphragm inside the lens.
- A cross section of the antenna exposed to the satellite signal.
- The opening of a lens that controls the amount of light reaching the surface of the pickup device. the size of the aperture is controlled by the iris adjustment. by increasing the f-stop number (f/1.4, f/1.8, f/2.8, etc.) less light is permitted to pass to the pickup device.
- An opening in an optical system that limits the amount of light passing through the system.
- A small opening through which the electromagnetic radiation passes.
- The adjustable opening—or f-stop—of a lens determines how much light passes through the lens on its way to the film plane, or nowadays, to the surface of the camera`s imaging sensor. “faster” lenses have wider apertures, which in turn allow for faster shutter speeds. the wider the aperture is set, the shallower the depth of field will be in the resulting image.
- The opening of a lens, the size of which is controlled by a diaphragm. the term is commonly used to designate f-stops, such as f/4, f/5.6 etc., which are actually arrived at by dividing the focal length of the lens by the diameter of the aperture. thus, f/11 on a 110mm focal length lens means the opening is 10mm. the wider the opening, the lower the f-number, the more light is let through the lens. each step in aperture represents a halving or doubling of light. thus, f/8 allows in half as much light as f/5.6, and twice as much light as f/11.
- The variable opening in the lens through which light passes to the film or digital sensor. measured in f-stops. i like to compare it to your pupil which opens and closes to allow more or less light to enter your eye depending on the brightness level of the room. learn more about aperture and how to use it here.
- The lens opening that allows more, or less light onto the sensor formed by a diaphragm inside the actual lens.
- The opening in an ophthalmic frame front into which the lens is inserted. aperture dimensions (in millimeters) do not include the depth of the lens grove.

- Отверстие; проём (в стене)
- A small, circular opening inside the lens that can change in diameter to control the amount of light reaching the camera’s sensor as a picture is taken. the aperture diameter is expressed in f-stops; the lower the number, the larger the aperture.
- In photography, the diameter of the aperture expressed in terms of the focal length of the camera lens. the greater the f-number, the less light reaches the film and the more in focus the objects in the foreground and the background will be. for example, with an f-number = 16 the objects in the far background will be in focus. whereas, with an fnumber = 2 the background will be blurry (while foreground objects are in focus).

- As a general term, implies extent. in astronomy, it is an arc of the horizon intercepted between the true east or west points thereof, and the centre of the sun, star, or planet, at its rising or setting. in other words, it is the horizontal angular distance of a star from the east or west points. it is eastern or ortive when the heavenly object rises, and western or occiduous when it sets, and is moreover northern or southern according to its quarter of the horizon.—amplitude, in gunnery, is the range or whole distance of a projectile, or the right horizontal line subtending the curvilineal path in which it moved.—amplitude, in magnetism, is the difference between the rising and setting of the sun from the east and west points, as indicated by the mariner`s or magnetic compass—which subtracted from the true amplitude, constitutes the error of the compass, which is the combined effect of variation and local deviation.
