Shot with Tokina AF 12-24mm at 21mm (effective) focal length and window light and Nikon SB 600 with off camera sync chord heald high and to the left. Balanced nicely with the window light (to left also) at ISO 400 with day light from window. Holding the strobe high and to the left (about 11 o'clock) dropped any shadow that the strobe would produce, and gave a nice catch light. Strobe also helpful in photographing a black dog (Jake). Developed in Lightroom 3.
