to difficult to use

It's not hard, it can be if your computer can't handle it, then trying to select the object to focus on can be a pain, otherwise, it's pretty easy, just open the Super DOF menu and left click the object and part of the object you want to stay in focus, then change the blur factor to the desired setting and click Render then Take Screenshot
I understand that it can be a bother in some cases where it blurs things you don't want blurred, in those cases, you can just lower the blur or use Simple DOF
