Earlier in the day before this shot was taken, my brother was sitting where my Mum is, and the setting sun was shining in through the patio doors, lighting him up nicely from the left hand side of the shot. When this one was taken the sun had long gone down, and so I setup a strobe in the garden and balanced the flash with the ambient light in the room to get this setup. Strobist info: One Canon 580 EX II to the left of the scene, aimed slightly upwards with the little white bounce card out, set to 1/2 power. See my blog for more info on how I set it up.
