If you are a photography enthusiast, you probably own a DSLR camera. DSLR cameras offer a wide range of manual settings, allowing you to have full control over your images. One of the most important settings to understand is aperture. Aperture refers to the size of the opening in the lens through which the light enters the camera. It affects the depth of field, which determines how much of your image is in focus. Learning how to change the aperture on your DSLR camera will give you the ability to capture stunning photos with beautiful background blur or sharpness from front to back.
Changing the aperture on a DSLR camera may vary slightly depending on the make and model, but the basic concept remains the same. To begin, locate the mode dial on your camera. This dial allows you to select the shooting mode you want to use. Look for the “A” or “Av” mode, which stands for aperture priority mode. In this mode, you can control the aperture while the camera sets the shutter speed for proper exposure. Once you have found the aperture priority mode, rotate the mode dial to select it.
Once you are in aperture priority mode, your camera will display the current aperture setting on the LCD screen or through the viewfinder. It is usually displayed as an f-stop value such as f/2.8 or f/5.6. To change the aperture, look for a dial or button that is specifically designed for this purpose. It is often located near the shutter release button or on the back of the camera. Rotate the dial or press the button to adjust the aperture to your desired setting. Keep in mind that lower f-stop values like f/1.8 will result in a shallower depth of field, while higher f-stop values like f/16 will result in a deeper depth of field.
Once you have changed the aperture, your camera will adjust the shutter speed automatically to ensure correct exposure. Keep in mind that changing the aperture may also affect the overall brightness of the image, so it is important to review your histogram or use the camera’s built-in light meter to make sure the exposure is adequate. Experimenting with different aperture settings will allow you to explore creative possibilities and achieve the desired effect in your photographs. So, grab your DSLR camera, head out and start capturing stunning images by changing the aperture!
Understanding the Aperture Setting
The aperture setting is an important feature on a DSLR camera that controls the amount of light that enters the camera’s image sensor. It is one of the three key elements of exposure, along with shutter speed and ISO. By understanding how aperture works, you can have more control over the depth of field and the amount of light in your photographs.
What is Aperture?
Aperture refers to the size of the opening in the camera lens through which light travels. It is measured in f-stops, which are represented by numbers such as f/1.4, f/2.8, f/5.6, etc. The lower the f-stop number, the wider the aperture and the more light that can pass through. Conversely, the higher the f-stop number, the smaller the aperture and the less light that can pass through.
Depth of Field
One of the main effects of changing the aperture setting is the impact on the depth of field in a photograph. Depth of field refers to the range of sharpness in the image, from the foreground to the background. A wide aperture (low f-stop number) creates a shallow depth of field, where only the subject is in sharp focus and the background is blurred. This is commonly used in portrait photography to isolate the subject from distractions. On the other hand, a narrow aperture (high f-stop number) creates a larger depth of field, where objects in both the foreground and background are in focus. This is useful in landscape photography, where you want everything to be sharp and in focus.
Exposure Control
The aperture setting also plays a role in controlling the exposure of the photograph. A wider aperture allows more light to enter the camera, resulting in a brighter image. This is useful in low-light situations where you want to capture more light. Conversely, a narrower aperture restricts the amount of light entering the camera, resulting in a darker image. This can be advantageous in situations where you want to create a silhouette effect or reduce the exposure of a bright scene.
It’s important to note that changing the aperture setting will also affect the shutter speed and ISO settings, as the three elements work together to achieve the desired exposure. When you adjust the aperture, the camera will automatically adjust the shutter speed and/or ISO to maintain the correct exposure.

What is Aperture and its Importance in Photography
In photography, aperture refers to the opening in the lens that allows light to pass through to the camera’s image sensor. It is one of the three key elements of exposure, along with shutter speed and ISO. Aperture is commonly represented by an f-number, also known as f-stop, which indicates the size of the opening.
Understanding Aperture
Aperture controls the amount of light that reaches the sensor, as well as the depth of field in an image. A wide aperture (small f-number) lets in more light and creates a shallow depth of field, resulting in a blurred background and a sharp subject. On the other hand, a narrow aperture (large f-number) allows less light and produces a greater depth of field, keeping both the foreground and background in focus.
Aperture also affects the exposure of a photograph. When shooting in bright conditions, using a smaller aperture helps to reduce the amount of light entering the camera, preventing overexposure. In low light situations, a wider aperture lets in more light, ensuring proper exposure.
Choosing the Right Aperture
The choice of aperture depends on the desired creative effect and the shooting conditions. Portrait photographers often use wide apertures to isolate the subject and create a pleasing bokeh effect. Landscape photographers, on the other hand, typically choose narrower apertures to capture the entire scene in sharp focus.
It is important to note that the smallest or largest aperture setting may not always produce the best image quality. Each lens has an optimal aperture range where it performs at its sharpest, which is typically around two stops down from the widest aperture. Experimenting with different apertures is essential to understand the characteristics of a lens and achieve the desired result.
- A wide aperture (small f-number) creates a shallow depth of field
- A narrow aperture (large f-number) increases the depth of field
- Aperture affects exposure and can be adjusted based on lighting conditions
- The choice of aperture depends on the desired creative effect and shooting conditions
- Each lens has an optimal aperture range for best image quality
In conclusion, aperture is an essential aspect of photography that not only controls the amount of light reaching the sensor but also helps to create the desired depth of field and exposure. Understanding how aperture works and experimenting with different settings can greatly enhance the visual impact of photographs.
Types of DSLR Cameras and their Aperture Control Options
DSL (Digital Single Lens) cameras are versatile tools that allow photographers to have full control over their images. One of the crucial aspects of photography is controlling the aperture, which determines the amount of light that enters the camera. Different types of DSLR cameras offer various aperture control options to cater to the needs and preferences of photographers. Here are some common types of DSLR cameras and their aperture control options:
| Type of DSLR Camera | Aperture Control Options |
|---|---|
| Full-frame DSLR | Full-frame DSLR cameras provide the widest aperture control options and are preferred by professional photographers. They often feature a dedicated dial or button to adjust the aperture directly. Additionally, they offer a broad range of interchangeable lenses with various maximum aperture settings. |
| APS-C DSLR | APS-C DSLR cameras, also known as cropped sensor cameras, have a slightly smaller sensor compared to full-frame DSLRs. These cameras usually have a dial or button to adjust the aperture, similar to full-frame DSLRs. The lens options for APS-C DSLRs are vast, with different maximum aperture settings available. |
| Mirrorless DSLR | Mirrorless DSLR cameras, as the name suggests, do not have a mirror mechanism like traditional DSLRs. Instead, they use an electronic viewfinder (EVF) to display the image directly from the sensor. Mirrorless DSLRs usually offer the same aperture control options as full-frame or APS-C DSLRs, with dedicated dials or buttons. |
| Entry-level DSLR | Entry-level DSLR cameras are designed for beginner photographers or enthusiasts who are just starting their photography journey. These cameras often have simplified controls, including an aperture priority mode that automatically adjusts the aperture based on the desired depth of field. |
It’s important to note that irrespective of the type of DSLR camera you choose, understanding and mastering aperture control is crucial for achieving the desired visual effects and creative control in photography.

Adjusting the Aperture on Manual Mode
When shooting in manual mode on your DSLR camera, you have full control over the exposure settings, including the aperture. Adjusting the aperture allows you to control the depth of field in your photos, which can greatly impact the overall look and feel of your images.
Step 1: Switch to Manual Mode
To adjust the aperture, you first need to switch your camera to manual mode. Look for the mode dial on your camera, usually located on the top or side. Rotate the dial to the “M” for manual mode. This will give you complete control over the camera’s settings.
Step 2: Locate the Aperture Control
The aperture control on your DSLR camera is typically a ring located on your lens. It is marked with numbers such as f/2.8, f/4, f/5.6, etc. Each number represents a specific aperture value. The lower the number, the wider the aperture and the shallower the depth of field. The higher the number, the smaller the aperture and the greater the depth of field.
Step 3: Adjust the Aperture
To adjust the aperture, rotate the aperture control ring on your lens to the desired value. Keep in mind that the available aperture values may vary depending on the lens you are using. As you change the aperture, pay attention to the changes in the viewfinder or on the camera’s LCD screen. You may notice the image getting brighter or darker.
It’s important to note that changing the aperture also affects the exposure. A wider aperture (lower f-number) lets in more light, while a smaller aperture (higher f-number) lets in less light. To maintain the correct exposure, you may need to adjust other settings such as the shutter speed or ISO.
Experimenting with different aperture settings can help you achieve the desired creative effect in your photos. A wide aperture creates a shallow depth of field, blurring the background and drawing attention to the subject. A small aperture produces a greater depth of field, keeping more of the scene in focus.
Changing the Aperture in Aperture Priority Mode
Aperture Priority Mode is a shooting mode on DSLR cameras that allows you to manually set the aperture while the camera adjusts the other settings, such as shutter speed, to ensure a proper exposure. This mode is beneficial when you want to have control over the depth of field in your images.

- Look through the viewfinder or use the LCD screen to compose your shot.
- Press the shutter button halfway down to activate the light metering system.
- Rotate the main command dial or rear dial to adjust the aperture value.
- As you change the aperture value, you will see the corresponding changes in the camera’s display or viewfinder. A lower aperture value (e.g., f/2.8) will result in a larger aperture opening, while a higher aperture value (e.g., f/16) will result in a smaller aperture opening.
- Take a test shot and review the image on the LCD screen or in the viewfinder to ensure the desired depth of field has been achieved.
- If necessary, adjust the aperture value again and repeat the test shot until you are satisfied with the results.
It’s important to note that changing the aperture will not only affect the depth of field but also the amount of light entering the camera. A larger aperture opening allows more light to enter, while a smaller aperture opening restricts the amount of light. As a result, you may need to adjust the ISO or use additional lighting to compensate for any exposure changes.
By mastering the ability to change the aperture in Aperture Priority Mode, you can create stunning images with the desired depth of field, whether you want a shallow, blurred background or a more extensive, sharp focus throughout the image.
Using Shutter Priority Mode to Modify the Aperture
When it comes to controlling the aperture on a DSLR camera, one of the easiest ways is to use the shutter priority mode. This mode allows you to set the desired shutter speed while the camera automatically adjusts the aperture to obtain the correct exposure. Here’s how you can use shutter priority mode to modify the aperture:
- Turn on your DSLR camera and set it to shutter priority mode. This mode is usually indicated by the letter “S” or “Tv” on the camera’s mode dial.
- Use the main command dial or the arrow buttons on your camera to adjust the shutter speed. This will determine the exposure time and freezing or blurring of motion in your photo.
- Look through the viewfinder or at the camera’s LCD screen and check the exposure meter. The exposure meter will indicate if the photo will be overexposed or underexposed based on the current settings.
- If the exposure meter indicates an overexposed photo, you will need to decrease the aperture. To do this, use the camera’s control dial to choose a higher f-stop value, such as f/8 or f/11. If the exposure meter indicates an underexposed photo, you will need to increase the aperture by choosing a lower f-stop value, such as f/2.8 or f/4.
- After adjusting the aperture, half-press the shutter button to preview the photo’s exposure. If necessary, continue adjusting the aperture until the exposure meter indicates a correctly exposed photo.
- Once you have achieved the desired exposure, fully press the shutter button to capture the photo.
By using shutter priority mode, you can easily modify the aperture on your DSLR camera to control the depth of field and achieve the desired creative effect in your photos. Experiment with different aperture settings and practice using shutter priority mode to become more proficient in adjusting the aperture on your camera.
