Yes. This will have a huge impact on photon settings. If you are still
making use of the "phd" variable, then set it to a huge value (like 100 or
maybe even bigger). If, for example, the "separation" of photons is 0.02,
then imagine a grid of photons with all photons spaced 0.02 POV units apart.
Now, if the size of your object is 1x1, then all is OK. But if your object
is 1000x1000, then you'll have TONS of photons.
