How to blur background in Photoshop
There are many ways to recreate Dept Of Field (DOF) effect using Photoshop, let's have a look at one of the better ones.

|
|
 |
1.
|
|
|
Open a picture you want to blur the background on.
|
|
| |
2.
|
|

Select the object or objects you want to keep sharp.
I selected the lion and the front part of the shot.
|
|
| |
4.
|
|
|
In the menu click File and choose Refine Edge... (Alt + Ctrl + R for a keyboard shortcut).
|
|
| |
5.
|
|
|
In the new window set Output to Layer Mask.
|
|
| |
6.
|
|
|
Choose the similar settings to mine and click OK.
You can choose the settings that work best for your selection.
|
|
| |
7.
|
|
|
You made the selection a bit smoother so the cut object should look much better then it would without using Refine Edge function.
|
|
| |
8.
|
|
|
In the menu click Filter, Blur and choose Lens Blur...
In the new window set the Source to Layer Mask and check the Invert option.
Click OK.
|
|
| |

|
|
|
Lets disable the layer mask we activated in previous step.
Right click the layer mask next to the layer thumb picture and choose Disable Layer Mask.
