One of the challenges in the studio when using off camera flash is getting the right balance between light on the background and your subject. I use the "Group" control on my Canon flash system to get the look I want.
For this shot, I used four Canon flashes: two on the backdrop and two for the subject. I set the backdrop flashes to "Group B" and the subject flashes to "Group A". I then used the flash control menu on the Canon 60D to play with the ratios between the two groups. When I want a bright background, the ratio can be as extreme as 8:1. Usually I'm set around 4:1 or 2:1.
By simply changing the settings in the menu on the 60D, I can adjust my lighting scheme without ever moving from the shooting position. If you haven't experimented using Groups this way, give it a try.

Derrick, I'm not sure how to put this, but the photo in this post looks as if the model is simply positioned for maximal flesh exposure. Looking forward to the more family-friendly postings you usually have. :)
