What is f-stop and how does it work?
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.
What does f stop mean in photography?
The term “F stop” can be really confusing if you are a beginner in photography. A smaller f-number corresponds to a larger aperture opening and a larger f-number corresponds to a smaller opening. You can see in the f stop chart that the opening is really big for an aperture value of f2.8 when compared to f11.
What does a big f-stop mean?
Remember: A big f-stop number means a small opening and a small f-stop number like f/1.2 or f/1.4 means a wide opening. Understanding Settings & Aperture in Just 2 Minutes!
What is the f stop chart infographic?
In this f stop chart infographic, we can see that the Aperture opening is arranged in descending order (w.r.t size of the opening). You can see three columns- full stop, ½ stop, and 1/3 stop. These values correspond to the Aperture value in your camera.
Is higher or lower f-stop better?
The lower the f-stop, the less depth of field and the blurrier the background. Increase the f-stop, and you'll get a greater depth of field and sharper background as a result. Discover photo tips and tricks as you begin experimenting with various aperture settings.
What f-stop should I use?
If someone tells you to use a large aperture, they're recommending an f-stop like f/1.4, f/2, or f/2.8. If someone tells you to use a small aperture, they're recommending an f-stop like f/8, f/11, or f/16. As you can see, an f-stop like f/2.8 represents a much larger aperture opening than something like f/16.
What does a higher f-stop do?
Your camera lens' f-stop (also known as an f-number) measures aperture — or, how much light is let in. A higher f-stop lets in less light than a lower f-stop would and it's used to create stunning photos under certain conditions.
What does f 2.8 mean in photography?
A camera's f-stop corresponds to the size of a lens's aperture–that is, the size of the hole in the lens that lets in light. F-stops are generally written like this: f/2.8, f/4, f/5.6, etc., and can span a range from around f/1.2 to f/32 (though there are some lenses that allow for even more extreme apertures).
When would you use a 1.4 aperture?
If the scene is so dark, you may need to shoot at a wide open 1.4 in order to get enough light - you're willing to trade extreme subject isolation and possibly not get the exact point of focus for noise and proper exposure.
IS f 4.0 A large aperture?
A large aperture is a wide opening of the lens, which allows it to capture more light. This is also called low ranging, since it's related to low F-stop values, usually ranging from f/1.4 to f/4.
Which aperture is sharpest?
If you're shooting flat subjects, the sharpest aperture is usually f/8. My lens reviews give the best apertures for each lens, but it is almost always f/8 if you need no depth of field.
What is the best f-stop for portraits?
The best aperture for individual portraits is f/2 to f/2.8. If you're shooting two people, use f/4. For more than two people, shoot at f/5.6. These aren't the only apertures you can use, and there are certainly other elements to consider.
Which f-stop lets in the most light?
The aperture setting is measured in f-stop values, with apertures such as f/1.4 and f/2.8 often referred to as 'wide' apertures, as they have the widest opening and let in the most light, while apertures with higher f-stop numbers (f/11, f/16 and so on) are (perhaps rather confusingly) referred as small, or narrow, ...
When should I use f2 8 aperture?
Such apertures are great for travel, sports, and wildlife photography. f/5.6 – f/8 – This is the right starting point for most landscape and architectural photography. It's also ideal for documentary and portrait photography where you don't want a blurry background.
Is f 4 or f 2.8 better?
An f/2.8 lens will give you twice the shutter speed of an f/4 lens when shooting with the aperture wide open. If you find yourself photographing moving people or other moving subjects, where fast shutter speeds are critical, then the f/2.8 is probably the right way to go.
Is f2 8 enough for portraits?
For many portrait photographers, the 70-200mm f/2.8 lens is considered the key to great results. This lens seems like it covers all the bases that any portrait photographer would want: wide aperture, a range of good focal lengths, and excellent build quality.
What F stop should I use for portraits?
Portrait photographers prefer wider apertures like f/2.8 or even f/4 — they can focus on the subject and blur the background. That's also why landscape photographers typically shoot in the f/11 to f/22 range — they want more of the landscape in focus, from the foreground to the distant horizon.
What is the best aperture to use?
Ideally, you would use a lens with a maximum aperture of f/2.8 or wider. When trying to get pinpoint stars, the goal is to let in as much light as possible (the stars are not that bright, after all). The way to increase exposure is to open up the aperture, slow down the shutter speed, and increase the ISO.
How do I know which aperture to use?
Aperture is denoted by a number, such as f/1.4 or f/8. The smaller the number, the wider the aperture. The larger the number, the smaller the aperture. If you're shooting in a low light environment, it's wise to shoot with a wide aperture to ensure we get a good exposure.
How does f stop affect a picture?
Larger apertures let in a lot of light, which makes them useful for low-light scenarios. F-stops in this range are also commonly used in portrait photography as the shallow depth of field makes subjects stand out while the background softens into a bokeh blur.
What does the F stop do?
Not only does your f-stop setting, or f-number, help you get a proper exposure, it also helps establish the look and feel of your photo by determining the depth of field. “Unless you’re working with a whole lot of light, or in very low light, your f-stop is usually more about style and how you want the photo to look than about necessity,” says ...
What does F stop mean in photography?
F-stops in photography measure how much light enters your lens and how bright your exposure is. Learn the ins and outs of aperture and how to pick the right f-stop setting for your shot.
What is the F stop on a camera?
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.
How to keep everything in focus when shooting indoors?
To keep everything in focus, you could shoot with a flash and keep your aperture in a medium range, or crank up your ISO to compensate for the low light.
What is the difference between focal length and f-stop?
While focal length itself refers to the field of view of a lens, f-stop is about how much light you allow to hit the sensor via the aperture opening. The aperture is the hole in the middle of the lens, made up of rotating blades that open to let in light when you press the shutter release. The diameter of the aperture determines how much light gets ...
What is the lowest f-stop?
The range of f-stops you can shoot with is entirely dependent on your camera lens. The lowest f-stop your lens can shoot with is called the maximum aperture. Many zoom lenses have a maximum aperture of f/2.8 or f/4, and some have a variable range. A prime lens, or a lens with a fixed focal length, can handle a wider aperture because it contains ...
Can you adjust a camera by full stops?
And while most film cameras can be adjusted by full stops only, most DSLR brands today allow you to choose from a wider range of increments. If you’re still familiarizing yourself with the f-stop scale, the Aperture priority shooting mode, abbreviated as Av, is a great way to learn how the exposure triangle works.
What is F-Stop?
The f-stop or f-number is the ratio between the lens focal length and the entrance pupil diameter. F-stop is the number shown in your camera that indicates the changes in the lens aperture size. It’s written as the f/2.8, f/4, and so on in the screen/ viewfinder .
Is the Higher F-Stop Better?
If what you mean by “higher” is a larger f-stop (f/1.4 and f/2), I must disagree.
Are Aperture and F-Stop the Same Thing?
Well, if you break down what f-stop is, it’s essentially the same. Most people use the terms f-stop and aperture interchangeably.
What is an F stop?
What is an f-stop? How to understand and master the camera jargon. By Tim Coleman June 27, 2021. What do those strange numbers on your lens actually mean? (Image credit: Pexels / Pixabay) As you begin exploring photography, you'll quickly come across the term 'f-stop', otherwise known as the f-number.
What does f stop mean in photography?
In purely literal terms, the 'f' stands for 'focal length' and a 'stop' is a unit of light, which refers to either the doubling or halving of the amount of light in your photo. But as that doesn't exactly clear things up, here's a more in-depth explanation of what an f-stop actually is – and how to use it in your photography.
What do f-stops mean in smartphone cameras?
Except for a couple of oddballs like the Samsung Galaxy S10, smartphone cameras generally have a fixed aperture, which means only one f-stop.
How does a f-stop affect a photo?
How to use f-stops in your photography. Using different f-stops (adjusting the aperture size) affects the amount of light entering the camera and therefore the brightness of the image. More light means greater clarity. Other qualities of the picture are affected by your choice of f-stop, namely the amount of your photo that will be in focus – in ...
Is f/4 a quarter?
For example , f/4 is a quarter, making it larger than f/8 which is an 1/8th. Therefore, the smaller the f-stop number, the larger the aperture. However, the 'f' in f-stop actually stands for focal length. It's a little complicated, but there is an equation comprising lens focal length and f-stop to work out the physical size of the aperture.
Can you use aperture and f stop in photography?
These examples are not rules though – photography is a creative practice, after all, and you can take some great photos by using aperture and f-stops in less common ways, such as shallow focus landscapes.
How to use a F stop?
Turn the control dial right or left according to the f-stop number you wish to use. Turning the dial right will give you a smaller aperture and turning it left will give you a wider aperture.
What is the F stop in photography?
The F-stop is part of the three components that make up the exposure triangle in photography. It refers to the aperture setting, the command that controls the size of the opening that allows light into the camera.
When to use a high f stop number?
You will want to use a high f-stop number when you are photographing landscapes or night photography with a tripod. When you raise the number, the amount of light that is let into your camera diminishes because the hole becomes smaller.
Are F-stop and Aperture the Same Thing?
F-stop stands for the aperture. The aperture is the function and the f-stop number is the actual command to control the aperture size in the camera.
What is an F-Stop and how is it calculated?
F-stops (also known as f-numbers) are units of measurement that let you know the size of the aperture.
What should my F-Stop be set at?
So by now, you might be thinking, “This is all quite fascinating, but I just want to know where to set my f-stop!”
How many f/stops is the sweet spot?
Every lens is different, but in general the sharpest aperture of your lens – otherwise known as the “sweet spot” – is two to three f/stops from its widest aperture.
What is the f number?
Mathematically speaking, the f-number is the ratio of the lens focal length divided by the diameter of the aperture. The result is a fraction where the “f” stands for focal length and the number following it is what you’re dividing it by.
How many stops does it take to go from f/2.8 to f/2?
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.
Is f/16 a wide aperture?
For example, in the chart above f/1.4 is quite wide open (a ‘wide’ aperture), while f/16 is little more than a pinhole (a ‘narrow’ aperture).
Is f/2.8 a good aperture for portraits?
Yes, f/2.8 is a great aperture for most single-subject portraits.
What Do F-Stop Numbers Mean?
Sometimes, they depend on which camera you have. That being said, all the f-stop numbers will represent a setting for the aperture relative to your lens’s maximum aperture. The larger f-stop numbers will still decrease the light entering your camera lens.
What is the F-Stop Used For?
The f-stop is used to represent your current aperture setting. There is an aperture scale represented by a series of progressing f-numbers. This is one of the trickiest things to understand. What you need to know is that smaller numbers mean a larger aperture setting while larger f-stop numbers translate to a smaller aperture setting.
How Does F-Stop Affect a Picture?
Your f-stop setting can affect the outcome of your photograph in a variety of different ways. The biggest is going to be with light. You need to learn which apertures make more sense in what lighting conditions to capture the photograph you desire.
What is the fstop of a 200mm lens?
For example, a 200mm lens using an f-stop of f/4.0 means the total diameter of your aperture is 50mm. In other words, it’s ¼ of the lens.
What is the smallest f-stop?
Always remember that the higher the f-stop number, the smaller the aperture. The smallest f-stop setting will be the most open your aperture can be, resulting in maximum exposure to light.
Does a fast shutter speed reduce light?
The key thing to understand here is that even if you have a wide aperture, a fast shutter speed can reduce the amount of light in an image. A very small aperture using a much slower shutter speed will actually let in more light than you may think. These are the kinds of factors you need to consider when taking professional photographs.
Definition: What are f-stops?
Otherwise known as aperture size, the f-stop regulates the amount of light that can pass through a lens at a given shutter speed. Assuming nothing else changes, a small aperture (say f/16) will let in less light than a larger one (say f/4) , so it would take longer for the same quantity of light to pass through to the sensor.
F Stop cheatsheet
Ever hear these terms? Stopping down the lens or aperture simply means to make the aperture smaller, such as from f/8 to f/11. Opening up, meanwhile, means doing the opposite.

How to Check the Maximum F-stop of a Lens?
If you are planning to buy a new lens or if you already own a lens, then you may be interested to know the maximum f stop of the lens.
What does a smaller aperture number mean?
A smaller f-number corresponds to a larger aperture opening and a larger f-number corresponds to a smaller opening.
How does the light falling in the camera sensor get reduced by half?
In other words, the light falling in the camera sensor gets reduced by half when you decrease the aperture by one full stop.
What is the last column in an infographic?
The last column in the infographic will give you an idea about the variation in exposure with a change in aperture opening.
What aperture is the tree in focus?
You can see that the person standing in front of the tree is in focus and the tree appears to be blurred when the aperture is at f2.8, which corresponds to a large opening.
How many apertures are there in 1/3 stop?
In the case of 1/3 stop, we are dividing a stop of light into 3 equal parts. So, between f2.8 and f4.0, we will have two more aperture values f3.2 and f3.5.
Why Aperture Is Important
Why Is Aperture Written as An F-Number?
- 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 on. Hopefully, you know how fractions work. …
What Does The “F” Stand for?
- 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 blades appear to be when you look through the front …
Which F-Stop Values Can You Actually Set?
- 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/4, or f/5.6. A lot of photographers reallycare about th…
F-Stop and Depth of Field
- 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/32 for the photo on the right. The differences sh…
What Is The Aperture Scale?
- 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 almost no light) These are the main aperture “stops,” but most cameras an…
Other Effects of F-Stop
- 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 to change brightness (exposure) and depth of field. …
Conclusion
- 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 aperture lets in a lot of light. If it’s dark out, and yo…
What Is F-Stop?
- The f-stop or f-number is the ratio between the lens focal length and the entrance pupil diameter. F-stop is the number shown in your camera that indicates the changes in the lens aperture size. It’s written as the f/2.8, f/4, and so on in the screen/viewfinder. Although some cameras may not display the “/” symbol or use a capital “F” instead, it s...
Smaller and Larger F-Stop
- We have all been confused with the smaller and larger aperture concept. Yet, the hint has been in front of us the whole time. The F in F-Stop is like a fraction. To put it in practice, the f-stop of f/22 is equivalent to 1/22, F/1.4 is the same as 1/1.4. Think of it as pizza slices. When you cut the pizza into a half (½), you will have a larger portion than cutting it into one eighth (⅛), right? This metap…
What Does The F Stand For in F-Stop?
- The answer is it stands for focal length. If you have a Canon EF 70-200mm f/4 lens fully zoomed in, the aperture blades’ diameter will be 200mm. Then divide 200 by 4 (4 because it’s the max aperture), and you’ll get 50 as a result. It means that the diameter of your aperture blades in the lens will be precisely 50mm. Using that example, we instantly know that the aperture blades will …
Why Aperture Is Important?
- Aperture will determine the focus and exposure of your image. Smaller apertures will give a photo with throughout focus from foreground to background. On the other hand, larger apertures will only focus on the foreground while blurring everything behind it. We have a full guide on apertureif you want to check that out later. Your choices of apertures should be suitable for your photogra…
Are Aperture and F-Stop The Same Thing?
- Well, if you break down what f-stop is, it’s essentially the same. Most people use the terms f-stop and aperture interchangeably. But if we want to be very accurate and precise, the difference is in the definitions. Firstly, the f-stop meaning is the ratio between the focal length and the aperture blade diameter (f-stop = focal length/diameter as mentioned earlier). Meanwhile, the aperture is …
Is The Higher F-Stop Better?
- If what you mean by “higher” is a larger f-stop (f/1.4 and f/2), I must disagree. Because having a higher f-stop does help you get as much light into the sensor as possible, but it will (again) completely blur the background. The smaller (below f/8) f-stop will also lead you to a problem because it decreases the exposure. The better option is to hover around the middle f-stop such …
When Should You Change Your F-Stop?
- Changing f-stops should be done if your subject is out of focus. Remember about the focal length earlier? It guides us to change our focus and f-stop whenever the subject moves forwards or backward. It would help if you also changed your f-stop whenever your photo is under-exposed or overexposed. When vignette (edges in photo getting disproportionally darker), diffraction (basic…
Final Remarks
- Let’s wrap this up: 1. F-stop is a number based on your aperture. The numbers are fractions, making f/1.4 larger than f/22. 2. “F” stands for focal length, which means the diameter of the camera’s aperture blades. 3. Aperture helps you control the brightness/exposure and depth of field of your photos. 4. F-stop and aperture are essentially the same but different in the little deta…
