Thank you!

The shadows are bright in my image because I used radiosity with a bright
environment, so there are no completely shadowed areas. However, if you have a
sphere and a single light source, a largely dark shadow with a single bright
spot is to be expected. It only looks odd because you don't often get that
lighting setup in reality.

Having said that, count does need to be fairly high to get good results. I
typically use at least 1e6, but 1e4-1e5 could be sufficient for something
really simple like a sphere.

Sometimes, the knowledge that something can be done is all the motivation you
need to work out how to do it. :)
