How To Define And Take Control Of Aperture In Photography
by Luke Walker
If you're new to photography, there's a high chance that you don't have a solid grasp of how to define aperture (in addition to several other things, which we will help you to learn about in other pages on this site). In this article I want to teach you precisely what aperture is and how to use it.
Simply put, aperture is your camera lens opening and closing. Let's say that you are somewhere dark taking shots. If your aperture is small, less light will come in. You would have to allow more light to enter your camera by opening the aperture.
You have to know about the numerical values of F stop. This decides the slice of of aperture. The smaller the F number, the lens will be wider. If you want more light to come through, we should use a smaller F stop number. With larger F stop values such as F stop 2, the aperture will be big. There is an opposite link between aperture and the F stop number.
By selecting various F stop values, it is possible to create different effects, such as a blurred background in a portrait, or a landscape image where everything in the frame is in focus. With an aperture of F2, the lens is wide open. Some lenses can go down to F1.4 and allow lots of light in, which can be perfect if it's dark.
With a larger F number the size of the opening is reduced. Bigger numbers mean smaller openings and smaller numbers mean larger openings.
To adjust this setting on your camera, rotate the dial on the top left to A or AV. This means Aperture mode. This is semi-automatic, meaning you pick the F stop number and your camera will calculate the ISO value and shutter speed for you.
Prime lenses that can go down to F1.4 are highly recommended, especially if you do a lot of portrait work.
To get blurred backgrounds, use lower F numbers (like 2.8 for example). As you increase the F stop number to F 4.5 or F 9, you will notice that the background will get sharper. Such backgrounds can also take attention away from the main focal point of the shot, so with portrait images you would probably be best off choosing smaller F numbers.For a group of people, landscapes and so forth, you will want to work with bigger F stop values.
Your camera will be set on auto focus single (instead of auto focus auto) otherwise the camera will decide what to focus on, as that is not what we want in this situation.
Thank you for reading this article. You should understand how to define aperture going forward, as well as how to use it when taking your photos.
