How to Blur Photo Backgrounds Easier Than Ever

By Melanie Doncas | Advanced Photo EditingInspirationPhoto Editor Tutorials

If there’s one thing the work of professional photographers has in common, it’s those beautifully blurred backgrounds that instantly transform a photo into a work of art. Aside from looking pretty darn good, blurred backgrounds work wonders at creating depth of field, placing the emphasis on the subject, or creating that dreamy bokeh effect we just can’t get enough of.

Before you start researching camera lenses in search of the perfect way to control the amount of blur in your photo background, we've got the best news for you: BeFunky’s Photo Editor has everything you could need to blur image backgrounds the way you want – in a single click! Powered by our very own AI technology, our collection of Blur tools will instantly isolate the subject in your photos and blur the background behind it. Forget fancy equipment – creating professional looking photos has never been easier!

Blur Backgrounds Like Never Before

In the past, blurring backgrounds in the photo editing process was a tedious task that required painting the blur effect around your subject. Depending on the shape of your subject and your painting skills, the results could vary widely. To give you more precision than ever and save you a tremendous amount of time, our team at BeFunky developed AI-powered technology to do the hard work for you! Just choose your favorite Blur tool (there are five to choose from with this tech!), click the Isolate Subject button, and watch the background blur while your subject stays crisp and clear.

Keep in mind that in order to automatically detect the subject in your image, there needs to be a strong main subject to detect. This technology works amazing with portraits, products, pet photography, and any image where there is a main subject to be emphasized. Here are some of our favorite ways to use it:

Create depth of field

Depth of field is simply a photography term that refers to the illusion of distance between the background and the foreground. This is achieved when the background of a photo is blurred and the subject in the foreground is sharp and in-focus.

You too can easily achieve this look by using the Blur tool with the Isolate Subject feature to create a realistic looking depth of field.

Emphasize Your Subject

Whether you’ve captured a portrait, a product, or something else, blurring backgrounds can quickly and easily get rid of distractions lingering in the background.

With a combination of the Blur tools and Isolate Subject feature, you can keep your subject crisp and clear, while letting any other distractions blur into oblivion.

Add Drama

Nothing is quite as dramatic as a colorful, light-filled cityscape captured at night, but if you want to turn up the drama even more, the Lens Blur tool can be used to transform light sources into intriguing bokeh.

A bokeh background is perfect for portraits, pet photography, and any kind of image where you want to emphasize the subject on dreamy background.

How to Blur Backgrounds with the Blur Tool

Ready to blur the background of your own photo? Head to the Photo Editor and upload a photo of your choice. Then, in the Edit tab on the left, scroll down to select the Blur tool (located in the Blur & Smooth section).

When you click on the Blur tool, you'll notice that the entire photo becomes blurred. Fear not – we'll show you how to add the blur effect to the background only and keep the subject sharp.

If there are areas in the preview that need to be touched up, you can always use the Keep and Remove buttons and paint the details in after clicking the blue checkmark to confirm.

With the subject in your image isolated, the background should now be blurred and the subject should remain sharp. You can navigate back to the Adjust tab and use the Blur Amount slider to either increase or decrease your desired blur effect. Simply hit the blue checkmark to apply the effect.

Alternatively, you can blur your photo’s background using the Lens Blur tool. While this tool works on any kind of photo, it particularly shines on photos taken at night featuring lights, as it has amazing bokeh-producing powers. To access this tool, head to the Photo Editor and upload a photo of your choice. Then, in the Edit tab, navigate to Lens Blur.

The entire image will blur into beautiful bokeh, but we'll show you how to add the effect to only the background. First, click on the Erase tab, followed by Isolate Subject.

Remember, if there are areas in the preview that need to be touched up, you can always use the Keep and Remove buttons and paint the details in after clicking the blue checkmark to confirm.

You’ll notice you have more options in the Adjust tab for this effect, giving you greater control over your blur. You can modify options such as Blur Amount, Bokeh Intensity, Blade Curvature, and Blade Count in the Adjust tab.

The Blur Amount slider will help you increase or decrease the amount of blur. Increasing the Bokeh Intensity will create more intense light orbs, while decreasing will create less intense orbs. The Blade Curvature controls the shape of the bokeh – adjusting the slider to the left gives your bokeh sharper edges, and to the right gives you circular edges. And finally, the Blade Count refers to the amount of blades you would find on a camera lens that control the aperture. The higher the blade count, the softer the bokeh will appear.
