Trying to add fog
I believe the fog setting only works with path tracer and hybrid-- it is time consuming and difficult since it does a volumetric calculation. I haven't tried it for a long time.
You might try a post-process fog-- saving the image as nXtImage and using the Haze setting in the Editor is one. There are others available in Photoshop, etc..
