GecT thanks for posting the results that way... it's great to see what happens when one setting is changed, and seeing what value was used in the change, and then changing another setting and seeing the difference and what each does. it helps the newbs in the tweaking process so they don't waste their time with a setting they shouldn't even be touching... plus having the images in close proximity also lets you see the differences in the values and their effects. nice.

when i was learning lighting and shadows (hell i STILL don't use MR, let alone haven't really learned how to use it) for raytracing and soft shadows and the like, there were only a few tutorials that helped, because instead of saying 'do this, now do this, now do this' (which just gave you their result instead of how to achieve your own) they would have images like yours that would show incrementations of settings to show you how it alters the render and to what extent.
