I've been trying to create a scene of a foggy night with street
lamps. I can get the atmospheric media to work on a small level,
typically when the scene is built using regular intervals. (i.e.
1.2.3.4....) but, for the sake of detail, I multiply all the dimensions
by 12 and use anything less than that for inches.
    Here's where I run into problems.  After a certain size, the media
ceases to function as expected.  Does My problem stem from my scaling?
If so do I have to scale everything down to unmanageably long float
values or can i modify the media statement to function on a large scale?

The density of the media isn't scaled when you scale the density,
so you'll have to decrease the density.

You can say that again. :-)

What if no density is used?

Make the color of your media darker.
That will decrease its density.

I believe density is considered to be rgb 1 by default even if a density
statement doesn't exist.  So, what Simon was reffering to is that you'll
need to add one in and use a smaller rgb.

I was reffering to the color you use in your scattering or whatever
statement
for example:
scattering{1,rgb <1,0.5,0.239>}

I see, sorry.  Either way should result in the exact same thing.
