If you haven't already, meet my wife. I rarely shoot portraits, but when Christina needed a photo taken for her work's website, I was more than happy to pull out my nifty 50mm f/1.4 and give it a shot. I'm extremely happy with how they turned out, especially this one.
The late afternoon light was perfect, and all I did in Lightroom was a little warming up of the white balance and boosting the contrast. It helps that the model was so good looking also.
