Wow, so much for Nodes for Dummies. This thread makes my head hurt. :)

Can we talk about Turbulence?

I've been attempting to get a satisfactory level of bump, and have been experimenting with Turbulence. I can't say I'm making a whole lot of sense of my experiments, so I need a basic understanding of what does what.

So some basic questions.

Does Turbulence interpret the bump map, or is it creating extra turbulence, quite apart from the map?

If I'm trying to get smoother and rougher, should I be doing this primarily with the Gain parameter, or the xyz Scales?

What's the difference between "Original" and "Improved" Noise Types?

What is Octaves? Is this a multiplier of some sort?

Edit: I guess part of what I'm trying to determine is whether I need to be doing most of my tweaking in the Material Room, or the real answer lies in improving my bump map itself in terms of levels of contrast etc. I'm struggling to get a balance between the visibility of wrinkles I'm creating over against the more general turbulence of the skin.
