3. Next, Select Magnetic Lasso Tool (Shortcut – L). And then make selection around the object you want to blur in the image. Make sure you put feather = 5 before making selection. Using feather is always good while making selection because it soften edges of the selection. You can adjust size of the feather. Minimum is 0 and maximum value it can take is 255. With feather you can create soft edge around the selection. If you want to blend images or adjust harsh edges then you should use feather.

5. Next, Click Filter >> Blur >> Motion Blur.
6. In the Motion Blur popup window, set Distance = 110 pixels, Angle = 0 degree and click OK. You will notice two settings in motion blur box i.e. Distance and Angle. Here, the distance is the length of blurring path. This is measured in unit pixels (px). The more distance path you set the more blur effect you will notice. The angle is the degree of inclination. If you select 90 degree then the background blur will be applied in a 90 degree angle.
7. Now to remove selection, click Select >> Deselect (Shortcut – Ctrl+d) on the menu bar.
