The best way to do this (without using MegaPOV which has a no_radiosity
flag) is create large black sphere that encloses your enitre scene and give
it no_image, no_reflection and no_shadow attributes.  This wayit doesn't
interact with your scene at all, but it will block out the radiosity
effects of anything outside it(i.e.,the sky_sphere).

If you take an outdoor photo with an interior film, everything will have a strong blue
cast. You 
don't notice it because your eyes are automaticaly compensating.
Optionaly, you can add a large white sphere with no_image. It will affect the
radiosity even if you 
can't see it. Also add no_reflection if you have any reflective object.
You can alter the colour of your object by making it a little yellow.
