![]() ![]() In addition your photos will have a shallow Depth of Field which helps to blur out some distracting stage elements behind the artists. This you can archive by setting your lens to the smallest f/number (big aperture). So, the only way to get a decent exposure is to let as much light into your camera as possible. Most of the time you have to deal with ultra low light situations during concerts. I shoot 95% of my concert shootings without exception with small f/numbers. With “fast” lenses I am referring to lenses with a small aperture number such as f1.4, f1.8 or f2.8. Get the „fastest lens“ within your budget. Summary of Aperture for concert photographers: The third component that influences DoF is the focal length of your lens. It makes a huge difference if the artist on stage is two meters away or he leans over to you and sings into your camera. The closer you focus on your subject, the shallower the depth of field. The distance between you and the subject also determines the DoF. Therefore portrait photographers often use an aperture of f/1.4 or f/2.8 to get this effect. The wider the aperture (the smaller the f/number) the smaller the DoF. This will result in a very shallow focus area in your picture and an out-of-focus foreground/background. A small f/number (large aperture) not only allow to let in more light, but also decreases the Depth of field. for me this is by far the most important factor to determine DoF. So, the depth of field determines the area that´s in focus and the aesthetic quality of the blur produced in the out-of-focus parts of an image is referred as BOKEH (japanese for blur). Everything in front and behind this point (plane of focus) is not in focus. When focusing your lens to a certain point, everything in the image on the same horizontal plane is in focus as well. models where only the eyes of the person are in focus whereas the background is blurry. I am sure you have already noticed this phenomenon in magazines or picture books of professional photographers. Simply speaking, Depth of field is the area of sharpness within a picture. Whereas when you are shooting a concert in low light conditions you should set the aperture wide open to let enough light hit you camera sensor.īut the aperture has an even more important function, namely to control Depth of field (DoF). It sounds obvious that when shooting on a sunny day in bright sunlight you should make the hole (the aperture) in your lens smaller. Why would you want to change the opening in your lens? Well, you might think that the only aspect to consider is to control the flow of light that hits the camera sensor. On the other hand, f/8 lets in twice as much light as f/11 and f11 lets in twice as much light as f/16. ![]() This means that f/4 allows half as much light as f/2.8 and f/5.6 allows half as much light as f/4. When you increase the f/number by a full stop (or one-stop increment) e.g from f/2 to f/2.8, the lens lets in half as much light as before. If you choose bigger aperture numbers you are „stopping the lens down“. When you set your lens to the smallest aperture number you are shooting „wide open“. Whereas f/numbers like 8, 11, 16 and 22 reflect the smallest opening which lets in less light. in physics, I´ll leave you with this explanation and rather focus on the practical aspects how to use these f-numbers for our advantage.į/numbers like 1.4, 2, 2.8, 4 and 5.6 reflects the widest opening (dependent on your lens) and will admit the greatest amount of light. Since I promised to explain it in a way that you don´t have to have a Ph.D. Technically speaking the f-numbers are ratios and are determined by dividing the diameter of the lens opening by the focal length of the lens. Especially, in the beginning, this nomenclature can lead to some confusion and it took me a while to figure out how f/numbers work. The smaller the f/number the larger the opening in the lens (large aperture). The exact same principle applies to the function of the iris of your eyes.Īpertures are also known by f-numbers. The smaller the opening, the less light can enter (small aperture). The larger the opening, the more light can enter (large aperture). This hole is formed by a series of overlapping metal blades (Diaphragm) and can be adjusted with your camera to make the opening larger or smaller. The aperture is the opening, or a „hole“ located inside the lens and allows you to select how much light hits the digital sensor of your camera. Fear not, this will be as basic as it can get.
