I had been trying to figure out how to get images like you see in the Nike ads. I always thought it was as much about the lighting as it was about the post processing but its about 25% lighting and 75% post. The nice thing is that the post processing is so simple, its a feature called the High Pass Filter. Its just a matter of making a layer, desaturate it, add the High Pass Filter and then combine the layers. The place where I learned to do it was on the Strobist blog
As far as the image itself goes I shot this with a 70-200 and had 3 SB-800s camera left and a silver reflector camera right.
