Depth of Field? (Blurring some area of the frame)
Is there any method that can be used to create a depth of field effect? Like a certain area of the frame is out of focus. I imagine it could be done with some kind of shader applied to a layer maybe? But it should only be on parts of the screen.. Any ideas for a good way to go about creating this?
The effect I am looking for can be seen in these videos for example:
