8 Easy Steps to Blur the Background in Photoshop

Following these eight easy steps will help you blur the background in Photoshop. In order to give you a good understanding of the process, we have added screenshots of each step.

Step 1: Load the picture in Photoshop

First of all, load the picture for which you want to blur the background. The image will be on the background layer. You can also resize the image if you think that the size should also be adjusted.

Step 2: Use Select and Mask to select the area in focus

The area in focus is the area you don’t want to blur. Click on the select tool and pick select and mask. Select the area in focus using any selection tool that you feel comfortable with.

Scroll down to “Output to” and select the “new layer with layer mask” option from the drop-down menu.

Step 3: Fill the black color in the focus area

Take on a new layer. Use a foreground or background color to fill in the black color in the selected area. Why do we fill black in this area? Because we want to make its depth map. We need to tell Photoshop that depth is from this point to this point. It means that everything that is black will not be blurred.

Step 4: Create a new layer with a gradient

Take a new layer beneath the above one and fill it with a black-and-white gradient. Press shift+click and drag your mouse after selecting the gradient tool.

After applying the above two steps, the layer panel will now look like this.

Step 5: take the layer with a gradient and place it on a channel

Click on the layer you just filled with a gradient, and then click on channels. Select any channel (Red, Green, or Blue) and make its copy. You can give any name to this channel. I named it “depth map”.

Just go back to RGB by selecting its name and then clicking on layers.

Step 6: Group all layers created so far

Select all layers by pressing the Ctrl button and clicking on each layer. Press Ctrl+G to group all the selected layers. Hide the group because we will not interact with any of the layers after this step.

Step 7: Make a copy of the background layer

You can make a copy of the layer by selecting it and then pressing Ctrl+J.

Step 8: Apply Filter

Go to the Filter menu and select Blur>Lens Blur. Once you are in the blur panel, select your source. Click on the drop-down menu and select your source. I had named it “Depth Map.”. Slide the radius slider to adjust the amount of blur you want. Check the preview tab to view the blur induced.
