This is an alternative Dof for your ENB.
It gives you only distant blur in 1st and 3rd person.
This blur is very static, so no obscuring while toggling between the 1st and 3rd person view, or while looking from far to close or close to far objects.
I don't know if this was done before but I could not find it, when I needed it. Well not as satisfying.

To change your blur distance all you need to do is changing "FarBlurDepth" Higher number for further away blur. Lower number for closer blur.
My default is 45.


This requires any ENB preset for Oblivion to work.
Install the file (in the zip) to your Data folder, where your Oblivion exe is.
