Photography F Stop Chart Understanding F Stops One thing that often confuses beginners is that small physical apertures have high f stop numbers like f 16 and f 22, while large (or "wide") apertures have low f stop numbers like f 1.4 and f 2. the reason is that f 16 represents one sixteenth, not sixteen, and f 4 represents a quarter, not four. •. F stops only refer to the size of the aperture. unlike stops of exposure, they don’t simply double or halve, but instead, depend on the f ratio. for example, going from f 2.8 to f 2 is one stop up. (remember, a smaller f number means a larger aperture!) going from f 5.6 to f 8 is one full stop down.
F Stop Chart Infographic Aperture In Photography Cheatsheet Understanding f stops: how to use f stops in photography. the single most important element of photography is light. simply put, without light, it is impossible to see the subject of a photograph. therefore it stands to reason that choosing the right amount of light is one of the most critical decisions a photographer will make about a given shot. The f number (also known as the focal ratio, f ratio, or the f stop) is the word we use when we’re measuring the aperture’s diameter. the blades – these bad boys close in or retract in a circular motion to make the aperture larger or smaller, according to your adjustments. you’ll want to use your f stop for two things:. F stops or f numbers are the units that measure the size of the aperture. this can be something like f 4 or f 8. many think the f stop is the focal length divided by the aperture diameter. but that’s not quite true. it’s actually the focal length divided by the “entrance pupil” or “effective aperture.”. An “f stop” is also called “f number.”. and perhaps “number” is a better way to think of it because it’s expressed as one. you will see “f 2.8” or “f 5.6” in articles about photos or lenses. in simple terms, the f stop tells you how large the lens aperture is at any given moment.

To recap: f stop (aka f number) is the number that you see on your camera or lens as you adjust the size of your aperture. since f stops are fractions, an aperture of f 2 is much larger than an aperture of f 16. just like the pupil in your eye, a large aperture lets in a lot of light. The amount of light that enters the camera affects the exposure and depth of field in the photo. f stop is represented in a series of numbers which increments in the stops of light, such as f 1.4, f 2, f 4, f 5.6, f 8, f 11, f 16, and so on. the difference between each value denotes one full stop of light. if you increase the f stop, you cut.
