f-number - Wikipedia
- https://info-aid.net/misyononline/en.wikipedia.org/wiki/F-number.html
- The f-number of an optical system (such as a camera lens) is the ratio of the system's focal length to the diameter of the entrance pupil. It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography. It is also known as the focal ratio, f-ratio, or f-stop.

- In these cases the working f-number is used. The working f-number N w is given by, where N is the uncorrected f-number, "NA" is the numerical aperture of the lens, and m is the lens's magnification for an object a particular distance away. [5] (Note that the magnification m here is negative for the common case where the image is inverted.) In photography, the working f …

- The F Number or F-Stop is used to express the aperture setting of a photographic lens. More technically speaking, this number is the ratio (the …
What Is An F Number? An Aperture Lesson
- https://photographycourse.net/aperture-f-number/
- The f in Aperture F Number simply stands for the lens’ focal length. That way no matter what the size of the lens, the f-number would be proportional or universally applied across all lenses. In other words, when using the aperture and shutter speed, using one lens will generate about the same exposure as using the same setting on a different lens. As you can see in the …
Aperture - Wikipedia
- https://en.wikipedia.org/wiki/Aperture
- A lens typically has a set of marked "f-stops" that the f-number can be set to. A lower f-number denotes a greater aperture opening which allows more light to reach the film or image sensor. The photography term "one f-stop" refers to a factor of √ 2 (approx. 1.41) change in f-number, which in turn corresponds to a factor of 2 change in light intensity. Aperture priority is a semi-automatic …
Lens speed - Wikipedia
- https://en.wikipedia.org/wiki/Lens_speed
- Lens speed refers to the maximum aperture diameter, or minimum f-number, of a photographic lens. A lens with a larger than average maximum aperture is called a "fast lens" because it can achieve the same exposure as an average lens with a faster shutter speed. Conversely, a smaller maximum aperture is "slow" because it delivers less light intensity and requires a slower …
Depth of field - Wikipedia
- https://en.wikipedia.org/wiki/Depth_of_field
- Depth of field changes linearly with F-number and circle of confusion, but changes in proportional to the square of the focal length and the distance to the subject. ... Aperture settings are adjusted more frequently in still photography, where variations in depth of field are used to produce a variety of special effects. Aperture = f/1.4. DOF ...
Exposure value - Wikipedia
- https://en.wikipedia.org/wiki/Exposure_value
- In photography, exposure value is a number that represents a combination of a camera's shutter speed and f-number, such that all combinations that yield the same exposure have the same EV. Exposure value is also used to indicate an interval on the photographic exposure scale, with a difference of 1 EV corresponding to a standard power-of-2 exposure step, commonly referred …
