Great tut Christian! I did a few tuts myself, and I know there goes a lot of work in a 'good' tutorial: and you did very well.
Clear and right to the point. You gave a lot of interesting tips and uses away, always worth watching it.
Specialy liked the 'homebrew smoke'. This reminds me of something:
I was looking for that for a while: Andrew K. also made a few on the subject, but I wasn't ready for it at the time.
I made a nature docu, filmed in the mist (fog), but I missed a few scenes. Of course when I went back, there was a harsh bright sunlight instead of the romantic hazy fog.
With your 'smoke' tip, maybe I'll be able to fix the sunny shots.
Thanx for this nice tutorial, and maybe yo will do some other ones in the near future? Hope so.
