What I don't quite understand is why the number of samples has so much
effect over the overall brightness of the media (I'm thinking of dense
scattering media to simulate SSS). Sure, the sample number should affect
the quality and presence of possible artifacts, but why is "samples 15" so
much brighter than "samples 75" (method 3, intervals 1)? Is this maybe due
to some bad coding on my part?
