If you set your camera to Aperture Priority (A or AV), you set the f-stop using the main command dial, and your camera adjusts the shutter speed accordingly. The aperture is a technical part of the lens and therefore not identical for every lens. In modern digital cameras, you can control the Aperture’s f-stops through the camera body. How/where do I change the Aperture setting? The lower the number (f-stop), the larger opening, which allows more light to pass through the higher the f-stop, the narrower the opening, with less light coming through the lens. To those of you who are yet unfamiliar with the definition of aperture, or f-stop, in photography, reading our article on the subject is the very first step to take before continuing.
What is aperture stop in photography Aperture Stops. An f-stop is a camera setting that specifies the aperture of the lens on a particular photograph. The size of the Aperture is measured in f-stops. So, an f-stop of 2 (f/2) means the lens aperture is half the focal length. In general terms, and for all types of photography, the Aperture is the unit of measurement that defines the size of the opening in the lens, which can be adjusted to control the amount of light reaching the film or digital sensor. Higher f-stop also, usually, means you need a longer exposure time. Le’s get to the practical uses of Aperture in photography rather than the scientific explanations. F-stop tells the cameras aperture how far to open.

So stick with me, and I’ll show you a way to understand the Aperture quite easily and learn how to use the Aperture not only to control the light (Exposure) but also the creative uses of Aperture. The wider the aperture the opening in the lens the smaller the f-number. My photography classes simplify all these terms to real-life uses of the camera’s settings. One stop is equal to a halving (or a doubling) of the amount of light let into the camera by that factor. F-stops (also referred to as f-numbers) refer to how open or closed the opening in your lens is.

Along with shutter speed and ISO (sensitivity to light), aperture is the third fundamental component that makes up the exposure triangle in photography. The aperture controls the amount of light that enters the camera lens and it’s measured in f-stops. It is good to know all these complicated scientific terms as photographers, but they don’t help us take better photos. F-stop is the term used to denote aperture measurements on your camera. It looks pretty complicated, doesn’t it? Easy Way to Understand the Aperture F stop (focal stop) is a value that indicates the size of the lens aperture used during the taking of a photograph. “In optics, an aperture is a hole or an opening through which light travels….” Let’s take a look at a definition of Aperture from Wikipedia: Understanding The Aperture in Photography for Beginners
