How to blur the background of photo on iPhone

Introduction

I bought my first digital SLR camera with a 50 mm lens. This lens creates a beautiful blurry background (bokeh) when making portraits. Unfortunately, with my iPhone 6s it is not possible to photograph portraits with blurred backgrounds. However, you can blur the background with the iPhone camera apps FabFocus and Focos 2.0 and the free photo editing app Snapseed.

iPhone Portrait Mode

Apple has, with the arrival of the iPhone 7 plus, given a lot of attention to photographing portraits with blurred backgrounds. The examples I’ve seen looked good and I think many people will decide to leave the “real cameras” more often at home. In the Portrait Mode of the iPhone 7 Plus, 8 Plus and iPhone X, Apple blurs the background with a combination of a dual camera and software. Google has succeeded with the Pixel 2 to achieve a similar result with a single camera and a software solution. That is why I have looked at whether it is possible to make portraits with blurred backgrounds on an iPhone with a single camera using an app.

Blur the background with the iPhone app FabFocus

I tested a number of apps and I was very satisfied with the results of FabFocus. I find the blurred background very realistic and the software can automatically select the subject. In most cases, the result is not flawless, but correcting the selected area is very easy.

How blurring the background works

You can take a picture with the app or import one. The app then automatically starts the editing process and searches for faces.

To correct the automatically selected area, tap edit. The selection is then displayed in green. You can expand the selected area with the pencil or reduce it with the eraser. The size of the pencil and the eraser are adjustable. To reduce the size of the selected area, tap with the eraser in the background and swipe with your finger. You can expand it by tapping with the pencil on the selection. Zoom in by tapping twice on the screen.

The settings

After you have adjusted the selection, tap the checkmark and the changes will be applied. If you tap on the sliders at the top right of the screen, you get a screen where you can select the shape of the blur and the amount. Tap on advanced for other settings, such as the resolution. It is fun to experiment with these settings and view the result.

Background blurring only for faces

The app FabFocus only works with faces. For other subjects you can try to create a blurred background by shooting with the iPhone Camera app. Get as close as possible to your subject with the background as far away as possible. (Update) Or you use the app Focos 2.0.

Blur the background with the iPhone app Focos 2.0 (Partly free)

With the handy app Focos you can take and import photos. The app automatically blurs the background of portraits and other subjects. The results look good.

You can even move the focus point by tapping the photo. In the second photo I moved the focal point in the photo of the doll to the background, so that the foreground is out of focus. In the third photo, I tapped on the area behind the doll on the right, so that the foreground and the background are out of focus.

Focos 2.0 has automatically blurred the background.

Features and settings

  • The app works with the front and rear camera.
  • You can take and import photos.
  • The app also works on iPhones with a single camera, such as my iPhone 6S. A number of older types are not supported.
  • You can set the amount of blur with the slider that appears when you tap the aperture icon in the bottom left.
  • You can move the focus point by tapping the screen.
  • The shape and brightness of the blur are adjustable.
  • If you have an iPhone with a dual camera, you can also take portrait photos with this wide-angle lens.

The app is partly free and you can save photos in medium resolution. For a number of extra functions and exporting in high resolution you need the paid Focos Pro version.

Conclusion

The apps are easy to use and give good results. In FabFocus you can also adjust the shape of the blur, but blurring the background only works for portraits. Snapseed (free) is a photo editing app, so you can also apply other edits and filters. In Snapseed and Focos 2.0 you can blur the backgrounds of portraits and other subjects. Focos 2.0 is partly free, works fully automatically and you can move the focus point afterwards.

Are you looking for an app that automatically blurs the background, then Focos 2.0 is a nice app to experiment with. You can even move the focus point. If you like to edit photos, Snapseed is the best choice.
