The beams are visible because they are brighter, right? Just use a 
dimmer background then. You can't get whiter than white. I'm not sure 
what you want white beams on a white background to look like...kind of 
like a polar bear in a snowstorm. If the beams are colored...well, you 
still have them being added to a 100% white background. Absorbing or 
extinction will make the beams visible by blocking the background...not 
white any more. The dynamic range patches floating around recently might 
be able to do what you want, otherwise you will have to post process the 
image.
