Another vote for Julieanne Kost.
I watched one of Morganti's "tutorials" and the first thing he did was slam the highlights & shadows sliders to 100%, which I thought was very bad advice.
I haven't watched any more of Morganti's efforts, although I know some people think he's wonderful.
The trouble with YouTube, and the internet in general, is that anyone can proclaim themselves an "Expert" and post any old rubbish they want, and it's sometimes difficult to sort the good from the bad.
