Ladies and Gentlemen - introducing: Frederik Steinmetz! He has prepared an intermediate tutorial on Cylces. Not the usual "How to start Cycles and set up a simple scene" kind of tutorial but a guided tour around current pitfalls and lots of tips and tricks!

This is the first guest appearance of Frederik Steinmetz on BlenderDiplom, and believe me, there will be more! He is a veteran from CG Tuts+ just like me and shares the same spirit of teaching broad-range techniques that will be helpfull in many situations. This tutorial on Cycles, the upcoming Blender renderer of awesomeness, is full of them!
