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.
- A hole
- Апертура
- In astronomy. the opening of a telescope tube next the object-glass, through which the rays of light and image of the object are conveyed to the eye. it is
- 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).
- Perpendicular distance between adjacent rock walls of a discontinuity,
Aperture, английский
A measure of the width of the opening allowing light to enter a camera. (aka: f-stop)

Aperture (light and camera), английский
The camera, projector, or printer opening that controls the size and proportions of the recorded image - the frame. see: aspect ratio. the area from which light is emitted from a fixture is also an aperture and the size, among other factors, influences the quality of the light.
Aperture (апертура), английский
Отверстие объектива, контролирующее количество света, достигающее поверхности фотоприемника. размер апертуры контролируется установкой диафрагмы. чем больше f-число (f/1.4, f/1.8, r/2.8 и т.д.), тем меньше света достигает фотоприемника.

- In leather, this is the process of die-cutting small holes to form a pattern. the holes can vary in size, density and pattern. railroading: cutting fabric on the cross grain, usually to avoid seams in large upholstered pieces. fabric is also referred to as railroaded when the pattern runs horizontally off the bolt. fabric with directional patters or pile (such as velvet) should not be railroaded.

Production, английский
- Refers to a person acting more dramtic than they would in a show, making the situation epic. example after tasha got up, she caused even more of a scene by throwing her purse on the ground, punching her boyfriend, and stomping into a store. what she did was a production.
