You can fine tune the spacing on a per object basis using target.

target can be followed by a float. That value is a multiplicator to the 
spacing.
If you use target 0.5, the spacing for that object will be half the 
general spacing resulting in shooting 4 times as many photons to that 
object, and 8 times as many photons in a media.
Using target 2 will double the spacing and thus divide the photons 
density by 4 for that object.

It's good if you have about the right photons density in general but 
some object need more, or can do with less, photons.
