What background blur does and where to find it

Background blur — also called bokeh — softens everything behind your subject so your face or object stands out sharply. In Camera, the built-in Windows app, this feature lives in the Effects panel during a live preview or after you take a photo. You do not need a second app or special hardware; the blur happens through software processing on your existing webcam feed.

The effect works best when you are sitting at least two feet from your camera and have a few feet of space behind you. A cluttered desk, messy room, or distracting background becomes soft and blurred, which is why the feature is popular for video calls and photos you plan to share.

Camera applies the blur in real time if your PC has enough processing power. Older or lower-spec machines may show a delay or may not offer the feature at all — if you open Camera and do not see Effects, your device may not support it.

Key Takeaways

  • Open Camera, start a live preview, and tap or click Effects to find the blur option in the panel that appears.
  • Background blur works during live preview and on photos you have already taken, though the preview shows the effect more clearly.
  • The blur strength adjusts automatically; you cannot manually set how strong the effect is in Camera.
  • If Effects does not appear, your PC may not have the processing power to run background blur, or Camera may need an update.
  • For more control over blur strength or to blur backgrounds in older photos, you will need a separate photo editor like Paint.NET or Photoshop.

Opening Camera and starting a live preview

Press the Windows key on your keyboard, type Camera, and select the Camera app from the results. The app opens to a live preview of your webcam feed — you will see yourself or whatever is in front of the camera in real time.

Position yourself so your face or subject is centered and well-lit. Natural light from a window works better than overhead lights, which can create harsh shadows. Step back slightly so the camera captures your shoulders and some space around you; this gives the blur effect room to work and makes the subject-to-background separation clearer.

Do not take a photo yet. The blur effect is easiest to see and adjust while you are watching the live preview.

Finding and turning on the Effects panel

Look at the bottom of the Camera window for a row of icons or buttons. One of them will be labeled Effects — it usually looks like a wand or sparkle icon, though the exact appearance depends on your Windows version. Tap or click it.

A panel will slide in from the side showing different effect options. Scroll through the list until you see Background blur or sometimes labeled as Blur. Tap or click it once to turn the effect on.

Watch your live preview. The background should soften when ready, and your face or subject should stay sharp. If the blur is too subtle to notice, move closer to the camera or make sure there is actual depth behind you — a wall two inches behind your head will not show much blur effect.

Using blur during a video call or taking a photo

Once you turn on background blur in the Effects panel, it stays active for the rest of your Camera session. If you start a video call through Teams, Zoom, or another app while Camera is open with blur enabled, the blur will appear in your video feed to the other people on the call.

To take a photo with the blur effect, press the camera button (usually a circle icon at the bottom center of the window) while the blur is still active. The photo saves with the blur applied. You can then close Camera or turn the blur off by clicking Effects again and selecting a different effect or None.

The blur effect is not permanent in the way a filter is — if you close Camera and reopen it later, you will need to turn Effects back on and select Background blur again.

Why the blur might not appear or might look weak

Background blur requires your PC to process the image in real time, which demands a reasonably modern processor. If your computer is more than five or six years old, or if you are running many other programs at once, Camera may not have enough power to explore the blur smoothly. You might see the effect flicker, lag, or not appear at all.

The blur also works better when there is actual distance between you and the background. If you are sitting against a wall or very close to a bookshelf, the software has less depth information to work with, and the blur will be subtle or uneven. Moving your chair back a few feet usually helps.

If the Effects button does not appear in Camera at all, check that you are running the latest version of Windows. Open Settings, go to System, then About, and look for an Update button. Older versions of Camera did not include the Effects feature.

Adjusting blur strength and other options

Camera does not offer a slider or dial to make the blur stronger or weaker. The blur strength is automatic and adjusts based on what the camera sees. You cannot manually control it within the app.

What you can control is your distance from the camera and the background. Moving farther from the camera makes the blur effect more noticeable. Putting more space between yourself and the wall or objects behind you also increases the blur effect because the software has more depth to work with.

If you want more control — such as choosing exactly how blurred the background is, or blurring a photo you took months ago — you will need to use a separate photo editor. Paint.NET (free), Photoshop, or Affinity Photo all have blur tools that let you select the background and adjust the blur amount manually.

Saving and sharing photos with blur

When you take a photo in Camera with background blur turned on, the app saves it automatically to your Pictures folder in a subfolder called Camera Roll. The blur is baked into the photo file, so when you share it or open it later, the blur stays there.

To find your saved photos, open File Explorer, navigate to Pictures, then Camera Roll. You will see all your Camera photos listed by date. Right-click any photo to share it via email, copy it, or move it to another folder.

If you want to blur a photo you took before Camera had the blur feature, or if you want to change how much blur appears in an old photo, you will need to use a photo editor. Camera itself cannot edit photos that were not taken within the app.

Frequently Asked Questions

Can I use background blur during a Zoom or Teams call?

Yes, if you have Camera open with blur enabled before you start the call. However, Zoom and Teams also have their own built-in blur features in their settings, which may work better or give you more control. Check your video settings in the app itself first.

Does background blur work with an external USB webcam?

It depends on the camera and your PC's processor. Most USB webcams work with Camera, but older or very low-cost cameras may not provide enough image data for the blur effect to work well. Try opening Camera and checking if Effects appears; if it does, the blur should work with your camera.

What if I want to blur the background of a photo I already took?

Camera cannot edit existing photos. You will need a photo editor like Paint.NET (free), Photoshop, or Affinity Photo. These apps let you select the background and explore a blur filter manually, giving you control over how strong the effect is.

Why does the blur look uneven or patchy?

Uneven blur usually means the camera is having trouble figuring out what is foreground and what is background. This happens when you are very close to the camera, when the background is very similar in color to your clothing, or when your PC does not have enough processing power. Moving back and improving lighting usually helps.

Can I turn off the blur for just one photo?

Yes. Click Effects, then select None or a different effect. The blur turns off when ready, and your next photo will be taken without it. You can toggle blur on and off as many times as you want during a Camera session.
