Blurring the background in a photo can make your subject stand out and give your images a professional look. Many iPhone users want to achieve this effect but aren't sure how to do it effectively. This guide solves that problem by walking you through the process of blurring backgrounds using your iPhone's built-in features and apps.
The iPhone offers several ways to blur the background, primarily through Portrait mode and third-party apps. These tools help you create a depth-of-field effect, making your subject sharp while the background appears softly blurred, enhancing your photos' visual appeal.
How do you blur the background in a photo on iPhone?
You can blur the background on an iPhone by using the built-in Portrait mode or editing tools that simulate a depth-of-field effect. Third-party apps also offer advanced background blur features.
Portrait mode uses the dual-camera system or LiDAR sensor on supported iPhones to create a natural blur effect behind the subject. For photos taken without Portrait mode, you can use the iPhone's editing tools or apps like Snapseed or AfterFocus to add blur manually.
What prerequisites are required for blurring background in photos on iPhone?
- Compatible iPhone model: Portrait mode requires iPhone 7 Plus or later with dual cameras or LiDAR sensor for best results.
- Updated iOS version: Ensure your iPhone runs iOS 13 or later for the latest camera and editing features.
- Good lighting conditions: Proper lighting helps the camera distinguish the subject from the background for effective blur.
- Basic photo editing knowledge: Familiarity with the Photos app and third-party editing apps helps you fine-tune the blur effect.
How do you use Portrait mode to blur the background on iPhone?
Portrait mode is the easiest way to blur the background on supported iPhones. It uses depth data to keep the subject sharp while blurring the background naturally.
To use Portrait mode, open the Camera app and swipe to Portrait. Position your subject within the frame and ensure the lighting is sufficient. The camera will indicate when the subject is in focus. Tap the shutter button to capture the photo with a blurred background.
After taking the photo, you can adjust the blur intensity by editing the image in the Photos app. Tap Edit, then use the Depth Control slider to increase or decrease the background blur. This feature gives you control over how much the background is softened.
How do you blur the background in existing photos on iPhone?
If you have photos without background blur, you can still add the effect using the iPhone's editing tools or third-party apps. The Photos app allows limited background blur adjustments on Portrait photos but not on regular images.
For non-Portrait photos, apps like Snapseed or AfterFocus let you manually select the background area and apply a blur effect. These apps use masking tools to isolate the subject and blur the rest, simulating a depth-of-field effect.
Using these apps involves importing your photo, selecting the subject, and applying the blur filter to the background. You can adjust the blur strength and feathering to make the effect look natural.
Step-by-step guide to blur background in photo on iPhone
Step 1: Open the Camera app and select Portrait mode
Portrait mode is designed to create a blurred background effect. Open the Camera app and swipe to the Portrait option. This mode uses depth sensors to separate the subject from the background.
Open Camera app → Swipe to Portrait modeThis prepares your camera to capture photos with a natural background blur, also known as bokeh.
Step 2: Frame your subject and ensure good lighting
Position your subject within the frame, ideally 2 to 8 feet away. Good lighting helps the camera detect edges and depth accurately for a better blur effect.
Position subject 2-8 feet away → Ensure well-lit environmentProper distance and lighting improve the quality of the depth effect, making the background blur smooth and realistic.
Step 3: Capture the photo
Once the camera indicates the subject is in focus (yellow box), tap the shutter button to take the photo. The iPhone will automatically apply the background blur.
Tap shutter buttonThe photo is saved with the subject sharp and the background blurred, thanks to the depth data captured.
Step 4: Adjust the blur intensity in Photos app
Open the photo in the Photos app and tap Edit. Use the Depth Control slider (f-number icon) to increase or decrease the background blur.
Photos app → Select photo → Tap Edit → Adjust Depth Control sliderThis lets you fine-tune the blur effect to your liking, from subtle to strong background blur.
Step 5: Use third-party apps for non-Portrait photos
If your photo wasn't taken in Portrait mode, use apps like Snapseed or AfterFocus to manually blur the background. Import the photo, select the background area, and apply the blur filter.
Open Snapseed/AfterFocus → Import photo → Select background → Apply blurThis method simulates the depth-of-field effect on any photo, giving you creative control over the blur.
Step 6: Save and share your edited photo
After adjusting the blur, save the edited photo to your camera roll. You can now share it on social media or use it in your projects.
Tap Save or Export in editing appSaving preserves your edits, allowing you to access the blurred background photo anytime.
What are common background blur errors on iPhone and how do you fix them?
- Portrait mode not available: Older iPhone models or those without dual cameras may not support Portrait mode. Use third-party apps to blur backgrounds instead.
- Subject and background not separated: Poor lighting or complex backgrounds can confuse the camera. Improve lighting or simplify the background for better results.
- Blur effect looks unnatural: Overusing the Depth Control slider can create unrealistic blur. Adjust gradually and check the photo for natural appearance.
- Blur not applied on existing photos: Photos app only edits Portrait mode photos for blur. Use third-party apps to add blur to regular photos.
- App crashes or slow performance: Large photo files or insufficient device memory can cause issues. Close other apps and restart your iPhone before retrying.
What are best practices when blurring background in photos on iPhone?
- Use Portrait mode on supported devices: It provides the most natural and high-quality background blur using hardware depth data.
- Maintain proper subject distance: Keep your subject 2 to 8 feet away for optimal depth effect and clear background separation.
- Ensure good lighting: Adequate lighting helps the camera detect edges and depth accurately for smooth blur.
- Avoid over-blurring: Use the Depth Control slider moderately to keep the photo looking realistic and professional.
- Use manual editing apps carefully: When using third-party apps, take time to mask the subject precisely to avoid blurring parts of it.
What iPhone apps are best for blurring background in photos?
Besides the built-in Photos app, several apps offer advanced background blur features. Snapseed is a popular free app with selective blur tools. AfterFocus provides easy background selection and blur adjustment. Lightroom Mobile offers professional editing with depth effect controls.
These apps allow you to add or enhance background blur on any photo, even those not taken in Portrait mode. They also provide additional editing tools to improve overall photo quality.
How do you edit background blur after taking a photo on iPhone?
For photos taken in Portrait mode, open the Photos app and tap Edit. Use the Depth Control slider to adjust the blur intensity. You can also change lighting effects like Studio Light or Natural Light to enhance the subject.
If the photo was not taken in Portrait mode, use third-party apps to manually add or adjust background blur. These apps let you select the background area and apply customizable blur effects.
What camera settings affect background blur on iPhone?
Background blur depends on depth data captured by dual cameras or LiDAR sensors in Portrait mode. The aperture and focal length are fixed on iPhones, but the software simulates blur by separating subject and background.
Distance between subject and background also affects blur strength—the farther the background, the stronger the blur. Lighting and contrast help the camera detect edges for better depth effect.
Conclusion
Blurring the background in photos on your iPhone enhances the focus on your subject and creates a professional look. Using Portrait mode is the simplest and most effective way to achieve this, leveraging your iPhone's hardware and software capabilities.
For photos not taken in Portrait mode, third-party apps provide flexible options to add or adjust background blur. Understanding how to use these tools and following best practices ensures your photos have a natural and appealing depth-of-field effect every time.
