Spectacular panning and in low light you still managed to get excellent detail, even in the moving parts! This is NOT easy to do and it's exactly what this shot needed! I've done panning where I liked the moving parts more blurred, but that's for people running, etc.. For a horse running it's nice to see the details so well. Fantastic!
Thanks! I just checked the properties on this one, and it was shot at Shutter speed: 1/125.00, F-stop: 2.5, ISO speed: 400.

These were taken two different nights, the second page being the night this one was taken.
