![]() So you have more than just the full f-stops available. Of course, that doesn’t change the relationship between the f-stops and the amount of light that falls on your sensor. The reason for this is that there are also half f-stops and third-f-stops. As a rule, you can determine in the menu of your camera whether you want to work with half or third f-stops. If you’ve experimented a little with the camera aperture, you may have noticed that your camera has more aperture stops than those. Perhaps you can set an aperture of f/3.5 or an aperture of f/7.1 on your camera, for example. With an aperture of f/4.0 your sensor reaches twice as much light as with an aperture of f/5.6, but only half as much as with an aperture of f/2.8. With every full f-stop, the sensor of your camera gets twice or half as much light. The individual steps between two values are called f-stops. So if you reduce your camera aperture from f/4 to f/5.6, for example, this is a difference from one f-stop. If you want to go a little deeper into the theory, then the additional knowledge on the subject off-stops is interesting for you. For a basic understanding of the camera aperture, you do not necessarily need it and you can skip it first and dedicate yourself directly to the practice in the following section.Īre you still there? Very well. Let’s give an example to understand better. Our standard lens has no small f-numbers like f/1.4, f/2.0, and f/2.8. It only starts at an aperture of f/3.5. Which numbers you can set depends on your camera and above all on your lens. So it is normal if the setting on your camera starts with a different f-number or if you have f-numbers between the ones mentioned here. This is a typical row of bezels: Typical row of apertures – from left to right the aperture of the aperture becomes smaller Say it out loud to yourself again: small number, a lot of light – large number, little light! If that sounds illogical to you, just think of the numbers after the f as a fraction. If we asked you if 1/16 (one-sixteenth) is greater than 1/8, what would your answer be? No! I agree. Just because the number 16 is larger, 1/16 is not more than 1/8. So: f/16 is smaller than f/8. f/16 lets in less light than f/8. We’ll explain what this is good for later and then try it out in practice. Then we can also see where the differences are in photos with different f-numbers.īut first, we have to work our way through the theory briefly. Do not give up! It’ll all make sense in a moment. So, back to the f-number.īurn this phrase into your brain: The smaller the number behind f /, the more light hits the sensor in your camera:Ī small number, large opening, lots of light – a large number, small opening, little light! So if you set f/4, a lot of light hits the sensor of your camera, and if you set f/13, very little light hits the sensor. Take a look at the following picture. You can see that there. The interesting thing now is: the higher the number behind the f/, the smaller the aperture. And vice versa: the smaller the f-number, the larger the aperture. The size of the opening is indicated by the f-number. When a photographer talks about the f-number that he used for a particular picture, he uses numbers like f/1.8, f/2.8, f/5.6. ![]() The camera aperture is the back opening of your lens. You can regulate the size of this opening yourself and thus determine how much light hits the camera’s sensor. The second setting is the shutter speed, which is the length of time your picture is exposed. The longer the shutter speed, the more light falls on the sensor. We’ll cover shutter speed in more detail in the next lesson. For this lesson, all you need to do is know that the shutter speed is there. ![]() There are two basic ways in which you can influence the exposure of your photo. One of them is the aperture, which is described in this lesson. With every sentence here everything becomes a little clearer and after you’ve tried it out, hopefully, there are no more questions. So, it’s best to take your camera with you right away.Ī small preliminary remark for a basic understanding: We will first define the term aperture for you and explain its function as simply as possible. Don’t let that put you off if you don’t understand everything right away. How to set the aperture and use it for your photos.How the aperture is related to the exposure time.How to blur the background of your subject.In this post you will learn, among other things: If you understand and master the aperture, photography is much more fun. So let’s get started right away. The camera aperture is one of the most important setting options on your camera.
