FWIW and if I'm not mistaken, count and spacing are two ways of 
specifying the same thing; either way, X number of photons are 
generated, with the only difference being that count lets you set the 
number directly while spacing makes POV-Ray determine how many to 
generate (not as useful as it sounds, since AFAIK there's no way to 
reconcile spacing with any meaningful real-world value, and if you set 
spacing too large, POV-Ray won't generate enough photons anyway).

If there's some reason why spacing is better than count, someone please 
feel free to point it out...

That said, I find you generally need a LOT of photons to get good 
results. If you use count, try something above 100000, and adjust upward 
as needed.
