This is how the aperture blades look on a typical lens:. Your lens probably looks something like this. It is made up of several blades — nine of them in this case, but your lens may differ. Aperture blades work a lot like the pupil in your eyes. At night, your pupils dilate so you can see things more easily. The same is true for aperture. When it is dark, you can open the aperture blades in your lens and let in more light.

It is very important to remember that aperture is a fraction. This is the biggest mistake beginners make when they talk about aperture. If you get this wrong, it will be difficult to remember how aperture works or use it yourself to capture the right exposure in the field. Because aperture is a fraction, all you need to do is remember some elementary math. It changes from lens to lens. This diagram demonstrates the relative sizes of various aperture settings:. So, which aperture setting is best for photography and capturing the proper in-camera exposure?

It depends upon the photo.

Aperture influences many parts of an image, but it has two effects that are more important than anything else: exposure and depth of field. The larger your aperture, the brighter your photo — the more light you capture.

Again, your pupils work just like this, too; they open or close to let in different amounts of light. So, when you are trying to expose a photo properly, it is crucial to pay attention to your aperture setting. A large aperture lets in more light. By changing your aperture and shutter speed settings, you can capture exactly the amount of light you want — resulting in a photo with the proper exposure. That is what makes aperture so powerful. Depth of field is the amount of your scene, from front to back, that appears sharp. In a landscape photo, your depth of field might be huge, stretching from the foreground to the horizon.

Aperture changes your depth of field, which makes a big difference if you want to capture the best possible photographs.

Changing the depth of field in an image will alter the way it looks completely. If you want everything from front to back to appear sharp, those are good settings to use. They are ideal if you are trying to isolate just a small part of your subject, making everything else blurred.

As you can see, that is a significant difference. The photograph on the left has a larger depth of field, which means that more of the scene appears sharp from front to back. In this case, it is arguably the better image.

Exposure and Health

The shutter speed scale is easy to remember. Unfortunately, aperture is not as intuitive. This is the scale it follows instead:. You also will increase your depth of field. Typically, the sharpest apertures will be somewhere in the middle of the range. However, this varies from lens to lens. In addition, sharpness should not be your main concern. It is better to have a photo with the proper depth of field, even if it means that some low-level pixels have a bit less detail. ISO is an interesting one.
