Distance fog and night lighting techniques.

[Heiko_Schmitz]

I am creating a night forest scene inspired by this image and I am struggling with the lighting and the fog setup: I want to have a slight mist which intensifies with distance and so that a bleak light source leaves light trails on it, just like in the bottom left corner of the image. How do I do it?
