Are you still annoyed by cluttered photo backgrounds? When you want to take a beautiful photo, you find that the background is messy, with pedestrians, peddlers and vehicles passing by. All these uncontrollable factors bring a chaotic look to your photo background.

Don't worry, we're here to help you solve this problem. You can blur the background of your photo, highlight the important subjects and weaken other objects in the photo to focus on the part of the photo you want to emphasise. Below we will share a few ways how to blur the background of a photo on iPhone.

How to Blur Background on iPhone When You Are Taking Photos

When shooting with your iPhone, it's easy to get a nice blurred background. In this section, we will share with you the two most convenient ways to blur background on iPhone.

Blur Background With Portrait Mode on iPhone

Portrait Mode is a basic feature of mobile phone cameras, so maybe you've used it, or maybe you haven't. But have you ever really understood Portrait Mode? In fact, Portrait Mode is an effect that simulates the large aperture and shallow depth of field effect of a professional camera by using an algorithm that focuses on the subject and defocuses the background to achieve a prominent portrait effect.

Portrait Mode is available on iPhone SE (2nd generation) and later, iPhone X and later, iPhone 7 Plus and iPhone 8 Plus. If you're using iPhone XR and iPhone SE (2nd generation), the rear camera must detect a face to take a Portrait mode photo.

Here are the detailed tutorials on how to blur background with portrait mode:

  1. Open the camera and select Portrait mode.
  2. Choose an effect from the six different light effects offered by iPhone as needed.
  3. Tap the shutter button

You can easily blur the background according to the three simple steps above. However, be aware that Portrait Mode does not work properly in low light conditions. If there is not enough light, a notification will appear telling you that you need more light.

Blur Backgrounds by Moving Closer to the Subject

If your iPhone's Portrait Mode isn't giving you the results you want, you should consider whether you're focusing at the right distance and shooting at the right distance.

1. The Right Focal Distance

In general, the phone camera to the subject of the portrait shooting distance should not be too far, so 0.5-2 meters is the best shooting distance.

Be careful not to be too close. It is easy to have big face pictures if you are too close, and the depth of field effect is not obvious if you are too far away. The right focus distance can ensure the depth of field effect, but also does not allow your subject to occupy most of the photo position.

2. Proper Distance Between the Subject and the Background

To have pictures with great blurred background, pay attention to the distance between the model and the background. The subject and background should not be too close to each other, otherwise the blur effect will not be obvious.

If your subject is too close or too far away, the system will remind you to move it closer or further away. When it is moved to the right position, a yellow box will appear in the camera as a reminder. This means your iPhone has successfully recognized the subject and background. The camera will automatically focus on the subject's face and blur the background.

How to Blur Background on iPhone in Photo Editing

When your shooting skills can not meet your demands, it's easy and quick to blur background in photo editing.

If you want to blur the background of your existing photos, you can follow the two methods below that allow you to edit your photos to get a nice blurred background.
