Wow... I definitely don't deserve to have a shot named after me! But thanks Chris. I learned this technique from the great Matt McGraw (he really showed me step by step) and by looking at work from Christobal Perez, Sol Tomargo, Matt Adcock, Marc Climie and lots of others. Frank Amodo does this really well too.
http://www.flashflavor.com is a site totally dedicated to using flash to enhance a photograph and create effects.
As far as what I do to get the shot... I set the flash at about 1/4 - 1/8 power either on a light stand or a monopod carried with me. The trick is to mess with f-stop. With most flash photography, the goal is to try to maintain the ambient light... but this works best when you expose for the highlights of the flash instead. When backlighting, I set my f-stop at f/8 or smaller.
It's a great way to draw attention to the subject. But it can quickly take over your photography. I've missed some really great shots because I was playing with the flash. So, be careful to keep the photography real too. But this is a great technique to add unique shots to your client's album! It can create a great sense of intimacy, bringing the viewer right into the heart of a dancing shot.
Have fun!
here are a few past examples:
My wife is standing underneath holding the flash in this one... I didn't even have to clone her out because it was so dark.




This is an extreme high/monopod angle with the flash off-camera.
