The Lens Blur panel in Camera Raw is the best way to blur backgrounds in Photoshop because it builds a real depth map instead of applying one flat blur.
You can click a single box and let Photoshop blur the background for you. The catch is rough edges and weird outlines around your subject.
This tutorial covers both: the one-click Lens Blur for quick jobs, and the professional two-layer method I use for clean edges, painted-in hair, and the freedom to move your subject after the fact.
By the end, you will be able to fake a shallow depth of field without an expensive lens, keep the edges clean, and come back to adjust the blur at any time.
Everything here works in Photoshop 2024 or the latest version.
Key Takeaways
- Lens Blur in Camera Raw builds an AI depth map of your photo, so the blur increases with distance the way a real lens renders it.
- The one-click Apply box works, but clean edges come from splitting the photo into a background plate and a masked subject first, not from the blur itself.
- Generative Fill with a blank prompt removes the subject from the background plate. Expand the selection about 10 pixels first so no edge pixels survive the fill.
- Digital blur looks too smooth. Around 5 points of grain in Camera Raw’s Effects panel makes the result read like a photo instead of a filter.
- Hair that is too difficult to mask gets painted back in with a custom brush. The free brush is in the download below.
- Adobe withdrew the Depth Blur Neural Filter. Lens Blur is its replacement, and it is better at the same job.

The Fast Way: Lens Blur’s One-Click Apply
Go to Filter > Camera Raw Filter and open the Lens Blur panel. Check the Apply box.
Photoshop uses AI to generate a synthetic depth map of your photo. That 3D depth estimation is what lets you change the focus plane and create a shallow depth of field, with the blur increasing as the scene recedes, the way a real lens renders it.
The controls worth knowing:
| Control | What it does |
|---|---|
| Blur Amount | Sets how strong the blur gets at full depth |
| Bokeh options | Choose the shape and character of the out-of-focus highlights |
| Boost | Intensifies the bokeh effect |
| Focal Range box | Widen it to keep more of the scene in focus, thin it to blur more |
| Visualize Depth | Shows the depth map: warm yellows are near, cool blues are far, and a white overlay marks what is currently in focus |
| Refine brushes | The Focus brush brings areas back into focus, and the Blur brush blurs what you paint over |
For a quick job, this is all you need. The weakness is edges. Lens Blur is great at blurring and not so good at masking, and the Refine brushes only get you so far. That is what the professional method solves.
The Pro Method: Split the Photo into Two Layers
The idea is simple. Rebuild the photo as two layers: a clean background plate with the subject removed, and the subject cut out on her own layer. Blur the plate, keep the subject sharp, and every edge stays clean because the subject was never part of what got blurred.
As a bonus, you can reposition the subject afterward, and everything stays editable.
Step 1: Duplicate and Name Your Layers
Press Ctrl J (Windows) or Command J (macOS) to duplicate the image layer, and name the copy Subject. Naming your layers keeps the file organized, and this technique builds a few of them.
Step 2: Select the Subject and Expand the Selection
Hide the Subject layer and activate the original background layer. Click Select Subject in the Contextual Task Bar, and Photoshop’s AI finds the subject and builds the selection.
Now expand it. Choose Select > Modify > Expand and enter about 10 pixels, then press OK. The gap between the selection edge and the subject’s body is what prevents ghosting and leftover edge pixels after the fill.
Tip: Add the subject’s shadow to the selection. Enable the Lasso Tool, hold Shift, and trace around the shadow below the body so the fill removes it too.
Step 3: Remove the Subject with Generative Fill
Click Generative Fill in the Contextual Task Bar, leave the prompt blank, and click Generate. Photoshop creates three variations with the subject removed. Pick the best one in the Properties panel.
Do not worry about perfection in the center of the fill. The subject will stand right there. The edges are what matter.
Note: On an older version of Photoshop, use Edit > Content-Aware Fill instead. It fills the area with content sampled from the surroundings. It works, but the results are not as clean as Generative Fill.
Step 4: Convert the Background into a Smart Object
Activate the Generative Fill layer, hold Shift, and click the background layer so both are selected. Right-click and choose Convert to Smart Object, then name it Background.
A Smart Object is a container that holds your layers and keeps every filter you apply editable. It is the reason you will be able to change the blur amount next week without redoing anything.
Step 5: Remove the Background from the Subject Layer
Enable the Subject layer’s visibility, then click Remove Background in the Contextual Task Bar. Photoshop selects the subject and applies a layer mask that hides everything around her.
Turn the Background Smart Object back on, and the image looks exactly like it did before. That is the point. It is now two layers instead of one, which gives you total control over what gets blurred, what stays sharp, and where the subject stands.
Step 6: Blur the Background with Lens Blur
Before you blur anything, note where your subject stands in the scene. That spot needs to stay in focus, because it is the plane she occupies.
With the Background Smart Object active, go to Filter > Camera Raw Filter, open the Lens Blur panel, and check Apply.
There is no subject in this layer anymore, so Photoshop keeps the center in focus by default. Click the Target icon, then click the spot where your subject will stand. Now the focal plane sits exactly where it should.
Raise the Blur Amount to taste and pick a bokeh type. The bubble option is my favorite. Add Boost if you want the highlights to bloom more.
Tip: Digitally blurred images look too smooth. Real photos carry grain. Open the Effects panel in Camera Raw and add about 5 points of grain so the result feels organic, then press OK.
Step 7: Fine-Tune the Layer Mask
The automatic mask on the Subject layer is strong, but it is not perfect. Click the Layer Mask thumbnail and enable the Brush Tool. Painting with white reveals the sharp original pixels, and painting with black hides them, revealing the blurry background underneath. Resize the brush with the bracket keys as you work.
For the edges, double-click the Layer Mask thumbnail to open the Select and Mask workspace. Set the View Mode to Black & White so the edges are easy to judge, then use Smooth to even out jagged edges and Contrast to sharpen them back up.
Tip: To smooth an edge by hand, click once with a black brush, then hold Shift and click somewhere else. Photoshop paints a straight line between the two points.
Step 8: Paint Hair Back Into Your Image
Hair against a busy background is the hardest edge in masking, and sometimes no selection will get it right. Professionals do not fight it. Hide the stray strands by painting black on the mask, then paint better hair back in.
Create a New Layer below the Subject layer and name it Hair.
Select the hair brush from the download below. Hold Alt (Windows) or Option (macOS) to sample a color from her hair, resize the brush with the bracket keys, and rotate the brush preview with the arrow keys until it matches the direction of her hair. Then click once to paint.
Repeat with different sampled colors so the painted strands vary like real hair.
Tip: If the brush adds strands you do not want, add a Layer Mask to the Hair layer and paint them away with a soft black brush.
Step 9: Reposition the Subject and Edit the Blur Any Time
Because the subject lives on her own layer, you can move her to make room for text or build a better composition. Hold Shift and click both the Subject and Hair layers, then click the link icon in the Layers panel so they move together. Enable the Move Tool and drag.
If her shadow disappears after the move, paint with white on the Subject layer’s mask to reveal it.
And the blur is never final. Open the Smart Object’s Camera Raw Filter smart filter, change the Blur Amount, add a vignette in the Effects panel, and press OK. The image updates with your new settings.
Alternative: The Tilt-Shift Blur Filter
Before Lens Blur existed, this effect was built with Filter > Blur Gallery > Tilt-Shift, and it still works well when your scene’s focus falls in a horizontal band.
Tilt-Shift blurs the top and bottom of the image and keeps a band of pixels sharp. Everything between the solid lines stays in focus. From the solid line to the dashed line, the blur ramps up gradually. Past the dashed line, you get the full blur set on the slider.
Position the sharp band over the plane where your subject stands, so the blur mimics what a lens with a shallow depth of field would capture. The two-layer split from the pro method applies here too: blur the empty background plate, not the subject, and you avoid the ghosting that gives this effect away.
Note: If you used the Depth Blur Neural Filter for this effect, Adobe has withdrawn it. Lens Blur in Camera Raw is the replacement, and its depth map does the same job with better results.
Which Blur Method Should You Use?
| Method | Best for | Watch out for |
|---|---|---|
| Lens Blur, one-click Apply | Quick jobs and social posts | Rough edges around the subject; the Refine brushes only partly fix them |
| Pro two-layer method | Client work, portraits, anything where edges and hair must hold up | Takes longer; the payoff is clean edges and full editability |
| Tilt-Shift Blur | Scenes where the focus falls in a straight band, like streets and products on a table | The blur follows the band, not real depth, so tall subjects need the two-layer split |
Frequently Asked Questions
Split the photo into two layers first. Remove the subject from the background with Generative Fill, cut the subject out onto her own layer with Remove Background, and blur only the background plate. The subject was never part of what got blurred, so the edges stay clean.
A panel in the Camera Raw Filter that uses AI to build a depth map of your photo. The blur increases with distance like a real lens, and you control the focal point, blur amount, and bokeh style. Open it from Filter > Camera Raw Filter.
Adobe withdrew it. Lens Blur in Camera Raw is the replacement. It builds the same kind of depth map with better results and stays editable when you apply it to a Smart Object.
Digital blur is too smooth. Real photos carry grain, and a blurred area with none reads as manipulated. Open the Effects panel in Camera Raw and add about 5 points of grain. A slight vignette can also help drive focus to the subject.
Yes, if you converted the background into a Smart Object first. Double-click the Camera Raw Filter smart filter, adjust the Blur Amount in the Lens Blur panel, and press OK. Nothing about the technique is permanent.
Do not fight a hair selection that will not cooperate. Hide the stray strands by painting black on the layer mask, then paint new strands on their own layer with a custom hair brush, sampling colors from the real hair. It looks better than any mask.
Lens Blur follows a depth map, so the blur changes with actual distance in the scene. Tilt-Shift keeps a straight band sharp and blurs above and below it. Use Lens Blur for people and depth, and Tilt-Shift when the focus falls in a band.
Blur Backgrounds in Photoshop Like They Were Shot That Way
Use the one-click Lens Blur when speed matters. Split the photo into two layers when the edges matter. Either way, add grain, keep the focal plane where your subject stands, and let the Smart Object keep every decision reversible.

Hello I Follow You Regularly I Learned Very Good Tips Thank You.
I’m your fan i’m really enjoying your your tutorials
And i learn a lots from you .
i need helped with that background Blur thank you from:april To: bingham and brabb
Thank you for the hair brush. This tutorial is so good. You are an excellent teacher!
I really appreciate your clarity and the follow on graphic of each step helps me be able to follow your actions. I am trying to learn PS and am having trouble with the basics. Like how to engage ACR. I think you find it by clicking on filters and the click on Camera Raw.
YOU ARE A GREAT TEACHER. LEARNT A LOT FROM YOUR VIDEO TUTORIALS
Thank you!
Thank You so much! This is a wonderful tutorial.By the way, where is download hair brush?
If the selcetion does not get all of the subject how do you expand to get all of the subject please
Make a Selection Out of The Main SubjectThe next step is to remove the background from the main subject to avoid edge halos upon blurring the image, and to give you more flexibility when masking the Foreground element.
To create a selection with the latest version of Photoshop, choose Select > Subject and allow Adobe Sensei, Photoshop’s Artificial Intelligence (AI), to study the entire image, find the subject, and create a selection out of it.
Thank you for the hair brush
great tutorial! the best of all I have seen. Thank you!
From where we can download the hair brushes??
This entire tutorial neglects to cover what happens when the background is more complex and the Adobe Sensei fails to correctly determine the subject. Completely useless for what I needed help with.
I agree and I feel this tutorial is missing quite a few steps as well.
Thanks so much for a brilliant tutorial! You’re a true saviour!
thanks a lot!
Jesus, following along with tutorial I end up with three files listed in PS. One is background and one is smart object and one is foreground. Do I save them all when done or only the smart object? Sorry if question is juvenile. Just starting to learn PS. Great tutorial!
Can you please give us the tutorial pictures?
