If you're just getting into photography, there's a pretty high chance that you don't know fully how to define aperture (as well as a few other important things in photography, which we will explain in other articles). In this article I want to enlighten you on exactly what aperture is and how you can use it to your advantage.
Simply put, aperture is your camera lens opening and closing. Pretend you are in a dark place taking photos. If you are using a small aperture, very little light will come in. So you need to allow more light to reach your camera's sensor by opening the aperture.
It is necessary for us to understand the numerical values of F stop. This determines the slice of of aperture. With a smaller F number, the wider your lens will be.To enable more light to come in, you want a smaller F stop value. With bigger F stop numbers such as F stop 2, the aperture will be big. There is an inversely proportional relationship between aperture and the F stop number.
By working with various F stop numbers, you can make various effects, for example a blurred background in a portrait photo, or a landscape photo where everything in the frame is in focus.With an aperture of F2, the lens is wide open. Some lenses can go as low as F1.4 and allow even more light to shine through, which is perfect if it's dark.
With a larger F number the size of the opening decreases. The bigger the number, the smaller the opening and smaller numbers mean larger openings.
To change this setting on your camera, rotate the dial on the top left hand side to A or AV. This means Aperture mode. This setting is semi-automatic, meaning you choose the F stop number and your camera will choose the shutter speed and ISO for you.
If you have the cash to spend, prime lenses which can go down to F1.4 can really be worth the extra money, especially if you do a lot of portrait photography.
If you want to have blurred backgrounds, you should use lower F numbers (like 2.8 for example). As you move up to F 4.5 or F 9, you will see the background details becoming crisper. Such backgrounds can also take attention away from the main focal point of the shot, so with portrait pictures you would probably be best off choosing lower F numbers. For landscapes, groups of people and so forth, it is best to choose bigger F stop values.
The camera will be set on auto focus single (rather than auto focus auto) to prevent your camera from deciding what it should focus on, as that is not what we want in this case.
So, now that you've read this article you should know how to define aperture pretty well, as well as how to use it when taking your photos.
