Guys! I've been looking for this kind of effect for a while now. I searched the forums and a lot of other places and somehow I managed to think of a simple way of reaching the effect I needed.
I know this is probably silly, but since I couldn't find something like this that didn't use outter plug-ins and stuff, I thought I'd share it with you guys.
Line of Sight - Effect based
Supposebly, if you change the effect from Brightness to blur, you could reach some cool results :D
