Quote - I don't think Reality can do much to solve fireflies. Fireflies are a rendering artifact in Luxrender..

You'll need to let it render longer, sometimes scenes require thousands of Samples/pixel. I've had scenes render for 2 days before I was satisfied. :)

Actually FFs will not go away with longer rendering. In fact they can get worse. There is a difference between FFs and render noise, they are not the same. FFs are caused, generally, by a combination of overlighting and glossiness set too high. With glossiness I mean thet combination of specular and glossiness strength. Those two should always worked together.

Render noise is just a function of the render not having enough data. There are many ways of optimizing the scene to make it render faster. Of course it all comes down to processor speed. Having a modern quad-core or higher will help greatly. 

Experience with Lux pays off greatly. I never have FFs in my scenes and very rarely I feel the need to do any post processing for tonal adjustment or such. Of course I have been using nothing else but LuxRender for the past 2.5 years so that amount of experience helps :)

Cheers.
