Here’s a great video from Joe McNally and Adorama TV. Joe’s working a Nikon D800 with the built-in flash as the commander flash, a Lastolite Ezybox softbox with grid and a red-gelled speedlight for a background light.
If you haven’t checked out Joe’s book, The Hot Shoe Diaries, there’s lots more of great speedlight info like this in there.
