Tuning global illumination

So I've added global illumination to this scene. You can see from the initial rendering that the default settings don't look very good. So there are a few things I need to do in order to improve the quality of this render. So I want to store this image and minimize it. And I'm going to take a look at my lights in the scene. So here is the point light, which is the photon-casting light. The way in which Global Illumination works is virtual photons are shot out from the point light, and when they contact the surface, a round area of lightness is created. So each photon has a round area of light.

These are blended together by mental ray to sort of create that indirect lighting effect. So the first thing I can do in order to improve the effect is increase the number of photons that are being shot out of this light. So the default setting is 10,000. I want to set this up to 100,000, and create another test render, and see if that's improved. It looks a little bit better. We're ...
