A few very good YouTube tutorials
If you have an interest in studio photography, these are pretty good. I like this guy's stuff, and he explains things pretty well to a neophyte. Obvious product placement, (Broncolor), but, hey, somebody has to make a living. He sells tutorials, but these are of very high quality for the free pricing. There's a few more on YouTube. Check out his website for more.
