You have probably noticed a fashionable and stylish effect of a defocused and blurred background in a wide variety of photographs with clear focus in the foreground. For example, a model shot clearly and brightly will look very profitable and unusual in a photo, but at the same time the background behind the model may be blurry and indistinct. Such a background accentuates the foreground, softens the photo, makes it more artistic and compositionally thought out.

Instructions
Step 1
Open the photo where you want to blur the background. Select the person or object that should be in the foreground using the Lasso Tool or any other selection method, trying to outline the path as detailed as possible. Copy the image to a new layer by right-clicking on the selection and choosing the Layer via Copy option.
Step 2
Go to the original background layer and open the filters menu. Select the Gaussian Blur filter and set the desired blur radius while watching the photo change in the preview window.
Step 3
For a strong blur, set the radius to 60-70 pixels. You will see how the background will become blurred, and the image of a person or any other object in the foreground will retain its clarity.
Step 4
However, if the contours of the person were complex, for example, you had to select a hairstyle with fluttering strands, the selection may turn out to be incorrect, and the photo may show bright boundaries between the blurred background and your character.
Step 5
To smooth out these areas, use the Lasso Tool and select all the bright parts of the background. Then go to Image> Adjustment> HueSaturation and change the hue and saturation of the selected areas. Reduce the saturation of the fragments to -59.
Step 6
Then use the blur option on the toolbar (call it with the R key) and process the selected areas. Adjust the Brightness / Contrast option in the Image menu to give the photo a finished look.
