As a photographer, understanding the fundamentals of aperture is crucial for capturing stunning images. Aperture is one of the three pillars of photography, along with shutter speed and ISO, and it plays a significant role in controlling the amount of light that enters the camera lens. However, many photographers, especially beginners, struggle to find and master aperture on their cameras. In this article, we will delve into the world of aperture, exploring what it is, how it works, and where to find it on your camera.
What is Aperture?
Aperture refers to the size of the opening in the camera lens that controls the amount of light that enters the camera. It is measured in f-stops (e.g., f/2.8, f/4, f/5.6), which represent the ratio of the lens opening to the focal length of the lens. A small f-stop value (e.g., f/2.8) means a large aperture opening, while a large f-stop value (e.g., f/16) means a small aperture opening.
Aperture affects not only the amount of light that enters the camera but also the depth of field, which is the area in focus in the image. A large aperture (small f-stop value) results in a shallow depth of field, where the subject is in focus, and the background is blurred. On the other hand, a small aperture (large f-stop value) results in a deep depth of field, where more of the image is in focus.
How Aperture Works
Aperture works by adjusting the size of the diaphragm, which is a mechanical iris that opens and closes to control the amount of light that enters the lens. The diaphragm is made up of several blades that move in tandem to form a circular opening. When the aperture is set to a small f-stop value, the blades move apart, creating a large opening that allows more light to enter the lens. Conversely, when the aperture is set to a large f-stop value, the blades move closer together, creating a small opening that allows less light to enter the lens.
Where is Aperture on a Camera?
Now that we understand what aperture is and how it works, let’s explore where to find it on your camera. The location of aperture on a camera varies depending on the type of camera you are using.
Digital Single-Lens Reflex (DSLR) Cameras
On a DSLR camera, aperture is typically controlled using the aperture ring or the camera’s mode dial. The aperture ring is usually located on the lens itself and is marked with f-stop values. To adjust the aperture, simply rotate the aperture ring until the desired f-stop value is selected.
Alternatively, you can use the camera’s mode dial to adjust the aperture. The mode dial is usually located on the top of the camera and allows you to switch between different modes, such as manual (M), aperture priority (A/Av), shutter priority (S/Tv), and program (P). In aperture priority mode, you can adjust the aperture using the camera’s control dial.
Mirrorless Cameras
On a mirrorless camera, aperture is typically controlled using the camera’s mode dial or the lens’s aperture ring. The mode dial is usually located on the top of the camera and allows you to switch between different modes, such as manual (M), aperture priority (A/Av), shutter priority (S/Tv), and program (P). In aperture priority mode, you can adjust the aperture using the camera’s control dial.
Some mirrorless cameras also have a lens’s aperture ring, which allows you to adjust the aperture directly on the lens.
Point-and-Shoot Cameras
On a point-and-shoot camera, aperture is usually controlled automatically by the camera. However, some point-and-shoot cameras may have a manual mode or an aperture priority mode that allows you to adjust the aperture.
Smartphone Cameras
On a smartphone camera, aperture is usually controlled automatically by the camera app. However, some smartphone cameras may have a manual mode or an aperture priority mode that allows you to adjust the aperture.
Mastering Aperture
Now that we have explored where to find aperture on your camera, let’s discuss how to master it.
Understanding F-Stops
F-stops are a fundamental concept in aperture, and understanding them is crucial for mastering aperture. Here are some key things to know about f-stops:
- A small f-stop value (e.g., f/2.8) means a large aperture opening, while a large f-stop value (e.g., f/16) means a small aperture opening.
- Each f-stop value represents a doubling or halving of the amount of light that enters the lens. For example, f/4 allows twice as much light as f/5.6, while f/2.8 allows twice as much light as f/4.
- F-stops are usually marked on the lens or camera in a sequence, such as f/2.8, f/4, f/5.6, f/8, f/11, f/16.
Using Aperture to Control Depth of Field
Aperture is a powerful tool for controlling depth of field, which is the area in focus in the image. Here are some tips for using aperture to control depth of field:
- Use a large aperture (small f-stop value) to create a shallow depth of field, where the subject is in focus, and the background is blurred.
- Use a small aperture (large f-stop value) to create a deep depth of field, where more of the image is in focus.
- Experiment with different f-stop values to find the desired depth of field for your image.
Using Aperture to Control Light
Aperture is also a powerful tool for controlling light, which is essential for capturing stunning images. Here are some tips for using aperture to control light:
- Use a large aperture (small f-stop value) to let more light into the lens, which is ideal for low-light situations.
- Use a small aperture (large f-stop value) to let less light into the lens, which is ideal for bright situations.
- Experiment with different f-stop values to find the desired amount of light for your image.

What is aperture and how does it affect my photos?
Aperture refers to the size of the opening in your camera’s lens, which controls the amount of light that enters the camera. A larger aperture (smaller f-stop number) allows more light in, while a smaller aperture (larger f-stop number) allows less light in. This, in turn, affects the depth of field in your photos, with larger apertures resulting in a shallower depth of field and smaller apertures resulting in a deeper depth of field.
Understanding aperture is crucial for capturing high-quality photos, as it allows you to control the amount of light and the depth of field. By adjusting the aperture, you can create a range of effects, from a blurred background to a sharp, in-focus image. Additionally, aperture can also affect the overall mood and atmosphere of your photos, with larger apertures often creating a more intimate and dramatic effect.
How do I find the aperture setting on my camera?
The location of the aperture setting on your camera can vary depending on the type of camera you have. On most DSLR and mirrorless cameras, you can find the aperture setting on the camera’s mode dial or in the camera’s menu. Look for the “A” or “Av” mode, which stands for Aperture Priority mode. This mode allows you to set the aperture manually, while the camera adjusts the shutter speed accordingly.
If you’re using a point-and-shoot camera or a smartphone, you may not have direct access to the aperture setting. However, many modern smartphones and point-and-shoot cameras have a “Pro” or “Manual” mode that allows you to adjust the aperture, along with other settings such as shutter speed and ISO. Consult your camera’s user manual or online documentation to find out how to access the aperture setting on your specific camera.
What is the difference between a large and small aperture?
A large aperture (smaller f-stop number) has a larger opening, which allows more light to enter the camera. This results in a shallower depth of field, where the subject is in focus and the background is blurred. A large aperture is often used in portrait photography to create a beautiful bokeh (out-of-focus area) and to separate the subject from the background.
On the other hand, a small aperture (larger f-stop number) has a smaller opening, which allows less light to enter the camera. This results in a deeper depth of field, where more of the image is in focus. A small aperture is often used in landscape photography to capture a wide scene with a large depth of field. Additionally, small apertures can also be used to create a sense of sharpness and clarity in images.
How does aperture affect the depth of field in my photos?
Aperture has a significant impact on the depth of field in your photos. A larger aperture (smaller f-stop number) results in a shallower depth of field, where the subject is in focus and the background is blurred. This is because the large aperture allows more light to enter the camera, which reduces the depth of field. Conversely, a smaller aperture (larger f-stop number) results in a deeper depth of field, where more of the image is in focus.
The depth of field also depends on the distance between the subject and the camera, as well as the focal length of the lens. A longer focal length and a closer distance to the subject will result in a shallower depth of field, while a shorter focal length and a farther distance will result in a deeper depth of field. By adjusting the aperture, you can control the depth of field and create a range of effects in your photos.
Can I use aperture to create creative effects in my photos?
Yes, aperture can be used to create a range of creative effects in your photos. By adjusting the aperture, you can control the depth of field and create a sense of intimacy or drama in your images. A large aperture can be used to create a beautiful bokeh, while a small aperture can be used to capture a wide scene with a large depth of field.
Additionally, aperture can also be used to create a sense of motion or blur in your photos. By using a large aperture and a slow shutter speed, you can create a sense of motion and blur in your images. Conversely, a small aperture and a fast shutter speed can be used to freeze motion and capture sharp images. By experimenting with different aperture settings, you can create a range of creative effects in your photos.
How does aperture relate to other camera settings, such as shutter speed and ISO?
Aperture is closely related to other camera settings, such as shutter speed and ISO. The aperture setting controls the amount of light that enters the camera, while the shutter speed controls the length of time that the light is allowed to enter the camera. The ISO setting controls the camera’s sensitivity to light.
When adjusting the aperture, you may need to adjust the shutter speed and ISO settings accordingly. For example, if you’re using a large aperture, you may need to use a faster shutter speed to prevent overexposure. Conversely, if you’re using a small aperture, you may need to use a slower shutter speed to allow more light to enter the camera. By adjusting the aperture, shutter speed, and ISO settings together, you can capture high-quality photos with the desired exposure and effect.
What are some common aperture settings and when should I use them?
Some common aperture settings include f/1.4, f/2.8, f/4, f/5.6, and f/8. The choice of aperture setting depends on the type of photography you’re doing and the effect you want to achieve. For example, a large aperture (f/1.4 or f/2.8) is often used in portrait photography to create a beautiful bokeh and separate the subject from the background.
A medium aperture (f/4 or f/5.6) is often used in general photography, such as street photography or documentary photography, where a balance between depth of field and shutter speed is needed. A small aperture (f/8 or f/11) is often used in landscape photography to capture a wide scene with a large depth of field. By understanding the different aperture settings and when to use them, you can capture high-quality photos with the desired effect.
