APERTURE |'apətʃə| – это отверстие с переменным диаметром, которое позволяет контролировать количество света, проходящего через объектив
Aperture is the size of the opening in the lens. Think of the lens as a window large windows let in more light, while small windows let in less light. A wide open aperture will let more light into the image for a brighter photo, while a smaller aperture lets in less light.
Aperture is measured in f-stops; a small f-stop like f/1.8 is a wide opening, a large f-stop like f/22 is a very narrow one. Aperture is one of three camera settings that determine an image’s exposure, or how light or dark it is.
Aperture also affects how much of the image is in focus wide apertures result in that creamy, unfocused background while narrow apertures keep more of the image sharp.
relative aperture – а) светосила; б) относительное отверстие
Словосочетания:
to apply aperture compensation – корректировать апертурное искажение
aperture correction – апертурная коррекция
aperture mask – теневая маска
ACCENT LIGHT – точечный акцентирующий свет; направленное освещение; акцентирующий свет. Направленный свет дает на объекте резко выраженные света, тени и в некоторых случаях блики.
The directional lighting, the task of which is to highlight details or the whole object to attract the attention to them.
AL SERVO or CONTINUOUS FOCUS – непрерывный фокус, следящий
AI-Servo tracks focus on moving subjects so as your subject moves closer or moves further away your camera constantly updates focus to keep the subject as sharp as possible.
До тех пор, пока кнопка спуска находится в полунажатии, автофокус непрерывно работает, тем самым удерживая объект в зоне резкости.
ASPECT RATIO – понятие в фотографии, характеризующее формат изображения. Соотноше́ние сторо́н экра́на или Отноше́ние ширины́ ка́дра к высоте́.
If you’ve ever printed images before, you’ve probably noticed that an 8 x 10 usually crops from the original image. That’s due to aspect ratio. Aspect ratio is simply the ratio of the height to width. An 8 x 10 has an equal aspect ratio to a 4 x 5, but a 4 x 7 image is a bit wider.
You can change the aspect ratio in your camera if you know how you’d like to print your image, or you can crop your photo when you edit it to the right ratio.
