For this picture I used a flash off-camera left with a shoot-thru umbrella. This allows me to really frame the face with light.
This shot is all natural light but requires careful positioning to balance the face just right. Turn the face too much towards the window and you will wash out the right side... turn it too little and the left will be dark.
