Lighting Technique Q&A: Doorway Shot

QUESTION
How did the shot of the couple dancing in the doorway with the two lamps on each side happen? Was that staged? It doesn't look like it but it is perfect (it's towards the end of your slideshow).

ANSWER
The photo in the doorway at the end of the slideshow was a naturally occurring moment; the bride and groom weren't aware of my presence as I shot it. I had a White Lightning (inside the cottage) powered down to the minimum, bounced out of the far corner of the room triggered with a Pocket Wizard. I was shooting with one of my favorite lenses, the Canon 50mm f/1.4 (at f/1.4) on my Canon EOS 1D Mark II to pick up the ambient light from the two lights outside the building.
