What is multi-pass? What is it for?
Here is a video tutorial explaining that and some other related things (like gamma correction inside Shade).

Well, so anybody that uses Shade can benefit, even those without Photoshop (as the Gimp is free). And for those that do own Photoshop, you can still use what you learn here
Anyway, I hope you like it.
