F-numbers
Глоссарий по фотографии |
A series of numbers designating the apertures, or openings at which a lens is set. the higher the number, the narrower the aperture. for example, f/16 is narrower (by one stop) than f/11--it lets in half as much light. an f-number range might be f/2.8, f/4, f/5.6, f/8, f/11...to find the next aperture in a narrowing series, multiply by 1.4. f-numbers are arrived at by dividing the diameter of the opening into the focal length of the lens, thus a 10mm diameter opening on a 110mm lens is f/11. alternately used with f-stops.
