What is Camera Aperture: Everything You Need To Know

Do you want to know what is camera aperture? If yes, this article has all the information you need to know. Using the aperture in your camera correctly can help you take amazing photos and unlock a world of creative possibilities. But it can also be confusing to navigate if you’re new to photography.

The aperture is an essential part of the Exposure Triangle, which consists of ISO, Aperture, and Shutter Speed – all three elements must work together for good exposure. In this article, we will discuss everything you need to know about using the aperture in your camera so that you can create beautiful photographs with ease!

What is Camera Aperture?

Let’s start with knowing the basics. The aperture is a hole that allows light to pass through your camera lens, and it’s measured in f-stops (f/1.4, f/2, f/2.8, etc). The larger the number on the aperture scale, the smaller the opening of the diaphragm becomes. This means that higher numbers let in less light while lower numbers let in more.

Aperture also affects depth of field, which is the area of your photo that appears sharp and in focus. A large aperture (smaller number) will result in a shallow depth of field, allowing for an attractive blurry background effect, whereas a small aperture (larger number) will result in a deeper depth of field and greater areas of your image that are sharp and in focus.

Knowing the basics of the aperture is key for creative expression with your photos, so let’s dive into how to control it!

How To Control Aperture?

Controlling the aperture on your camera is fairly straightforward once you get the hang of it. First, you will need to switch your camera into aperture priority mode (usually represented by an “A” or “AV” on your camera’s dial). This mode allows you to manually adjust the aperture while the camera takes care of other settings, such as shutter speed and ISO.

Next, you can use either a physical dial or a touchscreen selection to adjust the aperture. The lower the number, the wider the opening of the diaphragm, and more light will enter; whereas, a higher number means the opening is smaller and less light enters.

Finally, you can experiment with different apertures to see how it affects your photos.

How Does Aperture in Camera Affect the Photo or Video?

The camera aperture plays a major role in the quality and look of your photos or videos. For creative expression and great photos, it’s important to understand how the aperture works on your camera.

Using a wide aperture (lower number) will create a sharp subject with a beautifully blurry background, whereas using a small aperture (higher number) will allow for more of the scene to be in focus.

Aperture also affects exposure, which is the amount of light that reaches your camera’s sensor. A wider aperture means more light is allowed in, and a smaller aperture means less light is let in.

Standard Camera Aperture Value

Most standard lenses have an aperture range from f/2.8 to f/16, which is called the Maximum Aperture Value (MAV). This MAV allows for a good amount of light in low-light conditions and provides a shallow depth of field when using a wide or fast lens. If you want more light, you can increase the aperture to its next value.

Using the Camera Aperture Priority Mode

The most important thing that you should know when it comes to using a camera aperture is the Aperture Priority Mode. This mode allows you to manually adjust the aperture while the camera takes care of other settings, such as shutter speed and ISO. It can be a great way to experiment with different aperture values while capturing stunning photos or videos.


Camera aperture is an essential part of the Exposure Triangle, as it controls both light and depth of field in a photograph. Knowing how to control the aperture can help you create breathtakingly beautiful images as well as videos with amazing depth-of-field effects.
