The spacing is somehow proportional to how detailed the caustics are (not
precisely of course, this depends on the situation). This means
specifying spacing is very useful if you shoot photons at a varying number
of objects, you get similar results then. With a fixed count activating
photons on an additional object totally changes the outcome.
A disadvantage is of course you can't be sure in advance how many photons
will be shot. Specifying too small spacing can easily lead to a several
hundred MB photons data and hours of parsing time - you have better
control over this aspect with count.
