I took the following photo at Saratoga Race Course yesterday: The lens used was the 55-200VR at an aperture of 5.6. I would have liked to isolate the horse and jockey more, but don't really have the right lens to do it. So, my next best way is to do it in NX2 using Gaussian Blur for the background, right? What is the easiest way of separating (masking) the jockey and horse, so that I can blur only the background? Is it easier to somehow use Control Points (if so, please explain how), or do I need to trace the selection using my Wacom Tablet? I don't have that steady a hand, so would prefer to not rely on my tracing. Thanks!
