A couple weeks ago I posted about the Strobist article "Variations on a Two-Light Theme, Pt. 1", well yesterday they posted part 2 of the series - "Variations on a Two-Light Theme, Pt. 2".
So if you were anything like me you'll wanna jump right over there and take a look, because it's a great series with outstanding information.
For that matter, I think Strobist is the single greatest lighting resource on the web.
I have included the setup image below, so often if you see the setup first you think "Ain't no way you're gonna get a good picture here". And as usual, I'm wrong.
