Aug 14, 2024 · The f-stop number actually refers to the size of the aperture opening, calculated by dividing the lens's focal length by the f-number. For example, with a 200mm lens, an f/4 aperture would have a diameter of 50mm (one-quarter of 200mm). So, how does the f-stop, or aperture, impact your image?

A wide aperture means your lens is more open, letting more light reach the sensor. It might seem backwards, but a low f-stop actually means a wider aperture. For example, f/2 is a wide aperture, while f/13 is a narrow aperture. Typically, anything under (wider than) f/2.8 is considered a wide aperture, but it depends on your lens.

As we have previously defined, aperture is basically a hole in your camera’s lens that lets light pass through. It’s not a particularly complicated topic, but it helps to have a good mental concept of aperture bladesin the first place. Yes, aperture blades, which are also known as the diaphragmin optics. Take a look inside your camera lens. If you ...
The f-stop, which is also known as the f-number, is the ratio of the lens focal length to the diameter of the entrance pupil. If you did not understand that, don’t worry, because there is a much easier explanation of it for beginners. In very simple language, f-stop is the number that your camera shows youwhen you change the size of the lens apertu...
Why is your aperture written like that? What does something like “f/8” even mean? Actually, this is one of the most important parts about aperture: it’s written as a fraction. You can think of an aperture of f/8 as the fraction 1/8 (one-eighth). An aperture of f/2 is equivalent to 1/2 (one-half). An aperture of f/16 is 1/16 (one-sixteenth). And so ...
A lot of photographers ask me an interesting question: What does the “f” stand for in f-stop, or in the name of aperture (like f/8)? Quite simply, the “f” stands for “focal length”. When you substitute focal length into the fraction, you’re solving for the diameter of the aperture bladesin your lens. (Or, more accurately, the diameter that the blad...
Unfortunately, you can’t just set any f-stop value that you want. At some point, the aperture blades in your lens won’t be able to close any smaller, or they won’t be able to open any wider. Typically, the “maximum” aperture of a lens, which is also often referred to as “wide-open” aperture, will be something like f/1.4, f/1.8, f/2, f/2.8, f/3.5, f...
Along with the amount of light a lens aperture allows, it has one other huge effect on your photos – depth of field. I always find that it’s easiest to understand depth of field by looking at photos, such as the comparison below. In this case, I used a relatively large aperture of f/4 for the photo on the left, and an incredibly small aperture of f...
Here’s the aperture scale. Each step down lets in halfas much light: 1. f/1.4 (very large opening of your aperture blades, lets in a lot of light) 2. f/2.0 (lets in half as much light as f/1.4) 3. f/2.8 (lets in half as much light as f/2.0) 4. f/4.0 (etc.) 5. f/5.6 6. f/8.0 7. f/11.0 8. f/16.0 9. f/22.0 10. f/32.0 (very small aperture, lets in almo...
The second page of our aperture article dives into every single effect of aperture in your photos. It includes things like diffraction, sunstars, lens aberrations, and so on. However, as important as all that is, it’s not what you reallyneed to know – especially at first. Instead, just know that the two biggest reasons to adjust your aperture are t...
Hopefully, you now have a good sense of f-stop and the ways it affects your photos. To recap: 1. F-stop (aka f-number) is the number that you see on your camera or lens as you adjust the size of your aperture. 2. Since f-stops are fractions, an aperture of f/2 is much larger than an aperture of f/16. 3. Just like the pupil in your eye, a large aper...
Jul 25, 2024 · You might also want to use a wider aperture when you want to isolate specific subjects from their backgrounds. A portrait photographer, for example, would typically use a wide aperture of f/1.8 or f/2 so that all the focus can be placed on their subject at the expense of details in the background. This is known as having a 'shallow' depth of field.

Jan 8, 2024 · A lower f-stop, like f/1.4 or f/2, allows more light into the lens. This can help in low light and create a shallow depth of field with a blurred background. This might be good for portraits. A higher f-stop, like f/16 or f/22, reduces the light entering the lens. But it can increase the depth of field and create a sharper image overall.

The f-stop explained. F-stop is the term used to denote aperture measurements on your camera. The aperture controls the amount of light that enters the camera lens, and it’s measured in f-stops. Along with shutter speed and ISO (sensitivity to light), aperture is the third fundamental component that makes up the exposure triangle in photography.
