Blurring the background in camera is a fundamental technique used by photographers to create visually appealing images that draw the viewer’s attention to the subject. This technique is commonly used in portrait photography, wildlife photography, and street photography, among others. In this article, we will explore the different methods of blurring the background in camera, including the use of aperture, shutter speed, and camera lenses.
Understanding Aperture and Its Role in Blurring the Background
Aperture is one of the most critical factors in blurring the background in camera. Aperture refers to the size of the camera’s aperture, which is the opening that controls the amount of light that enters the lens. A large aperture (small f-stop number) allows more light to enter the lens, while a small aperture (large f-stop number) allows less light to enter the lens.
When it comes to blurring the background, a large aperture is essential. A large aperture creates a shallow depth of field, which means that the subject is in focus, while the background is blurred. This is because a large aperture allows more light to enter the lens, which creates a narrower plane of focus.
How to Use Aperture to Blur the Background
To use aperture to blur the background, follow these steps:
- Set your camera to aperture priority mode (A/Av mode). This mode allows you to set the aperture, while the camera adjusts the shutter speed accordingly.
- Choose a large aperture (small f-stop number) such as f/2.8 or f/4.
- Make sure that the subject is at a sufficient distance from the background. The farther the subject is from the background, the more blurred the background will be.
- Use a lens with a wide aperture, such as a prime lens or a zoom lens with a wide aperture.
Using Shutter Speed to Blur the Background
Shutter speed is another factor that can be used to blur the background in camera. Shutter speed refers to the length of time that the camera’s shutter is open, measured in seconds or fractions of a second. A fast shutter speed (short exposure time) is used to freeze motion, while a slow shutter speed (long exposure time) is used to create motion blur.
When it comes to blurring the background, a slow shutter speed can be used to create a sense of motion in the background, while keeping the subject sharp. This technique is commonly used in sports photography and wildlife photography.
How to Use Shutter Speed to Blur the Background
To use shutter speed to blur the background, follow these steps:
- Set your camera to shutter priority mode (S/Tv mode). This mode allows you to set the shutter speed, while the camera adjusts the aperture accordingly.
- Choose a slow shutter speed (long exposure time) such as 1/30s or 1/15s.
- Make sure that the subject is stationary, while the background is moving. This will create a sense of motion in the background, while keeping the subject sharp.
- Use a tripod or a monopod to stabilize the camera, as a slow shutter speed can cause camera shake.
Using Camera Lenses to Blur the Background
Camera lenses can also be used to blur the background in camera. Different lenses have different aperture ranges and focal lengths, which can affect the depth of field and the amount of background blur.
Types of Lenses That Can Be Used to Blur the Background
There are several types of lenses that can be used to blur the background, including:
- Prime lenses: Prime lenses have a fixed focal length and a wide aperture, making them ideal for blurring the background.
- Zoom lenses: Zoom lenses have a variable focal length and a wide aperture, making them ideal for blurring the background.
- Telephoto lenses: Telephoto lenses have a long focal length and a narrow angle of view, making them ideal for blurring the background.
How to Choose the Right Lens for Blurring the Background
When choosing a lens for blurring the background, consider the following factors:
- Aperture: Look for a lens with a wide aperture (small f-stop number) to create a shallow depth of field.
- Focal length: Look for a lens with a long focal length (telephoto lens) to create a narrow angle of view and a blurred background.
- Image stabilization: Look for a lens with image stabilization to reduce camera shake and blur.
Additional Tips for Blurring the Background
In addition to using aperture, shutter speed, and camera lenses, there are several other tips that can be used to blur the background in camera. These include:
- Using a plain background: A plain background can help to create a blurred background, as there are fewer distractions to compete with the subject.
- Using a wide-angle lens: A wide-angle lens can help to create a blurred background, as it has a wider angle of view and a deeper depth of field.
- Using a reflector: A reflector can be used to add light to the subject, while keeping the background dark and blurred.

What is background blur in photography?
Background blur, also known as bokeh, is a photography technique used to create a shallow depth of field, where the subject is in sharp focus and the background is blurred. This effect helps to isolate the subject from the surrounding environment, creating a visually appealing and professional-looking image.
The background blur effect can be achieved using a combination of camera settings and techniques, including aperture, shutter speed, and lens selection. By controlling the amount of blur in the background, photographers can draw attention to the subject and create a sense of depth and dimensionality in the image.
What are the benefits of blurring the background in photography?
Blurring the background in photography offers several benefits, including isolating the subject from distractions, creating a sense of intimacy and closeness, and adding depth and dimensionality to the image. By separating the subject from the background, photographers can create a more focused and visually appealing composition.
Additionally, blurring the background can help to reduce clutter and simplify the image, making it easier to focus on the subject. This technique is particularly useful in portrait photography, where the goal is to capture the subject’s personality and expression.
What camera settings are required to blur the background?
To blur the background in photography, you’ll need to use a combination of camera settings, including a wide aperture (small f-stop number), a fast shutter speed, and a lens with a wide maximum aperture. A wide aperture will help to create a shallow depth of field, while a fast shutter speed will help to freeze the motion and prevent blur.
Additionally, using a lens with a wide maximum aperture (such as f/1.4 or f/2.8) will help to create a more pronounced background blur effect. You can also experiment with different camera angles and compositions to enhance the effect.
What type of lens is best for blurring the background?
The best type of lens for blurring the background is a lens with a wide maximum aperture, such as a prime lens or a zoom lens with a constant aperture. Prime lenses, in particular, are known for their wide apertures and ability to create a shallow depth of field.
Some popular lenses for blurring the background include the 50mm f/1.4, 85mm f/1.4, and 135mm f/2. These lenses offer a wide maximum aperture and are ideal for portrait and close-up photography.
Can I blur the background in post-processing?
Yes, it is possible to blur the background in post-processing using image editing software such as Adobe Photoshop or Lightroom. However, this method can be time-consuming and may not produce the same level of quality as capturing the effect in-camera.
To blur the background in post-processing, you can use the “select and mask” tool to isolate the subject and then apply a blur effect to the background. You can also use the “depth map” feature in some image editing software to create a more realistic blur effect.
What are some common mistakes to avoid when blurring the background?
One common mistake to avoid when blurring the background is using too wide an aperture, which can result in an overly shallow depth of field and a loss of detail in the subject. Another mistake is not paying attention to the background, which can result in distracting elements that take away from the subject.
Additionally, using a lens with a narrow maximum aperture or a slow shutter speed can result in a lack of background blur, making the image look flat and two-dimensional. It’s also important to pay attention to the lighting, as harsh or uneven lighting can make it difficult to achieve a smooth background blur.
How can I practice blurring the background in photography?
To practice blurring the background in photography, start by experimenting with different camera settings and techniques, such as aperture, shutter speed, and lens selection. Practice shooting in different environments and lighting conditions to see how they affect the background blur.
You can also practice shooting portraits of friends and family, paying attention to the background and how it affects the overall composition. Additionally, study the work of other photographers and analyze how they use background blur to create visually appealing images.
