This shot is a great example of the ability to completely control ambient light through super fast shutter speeds with Nikon's CLS system.
This Yoga studio had a good amount of natural light coming in from many large windows that lined the entire wall to camera right.
By using the Nikon CLS system I was able to use flash with a sync speed of 1/1600 of a second. At that speed the ambient light was pretty much eliminated and only the light from the Nikon SB900 flash registered in the exposure.
