I did some experimentation at a sporting event last night (before my hands got frozen...) with a blur technique. The idea is to use a slower shutter speed while tracking a subject by moving the camera so that the subject is in focus while everything else is blurred. I didn't really get to the point where I could determine my optimal shutter speed because I ran into a different problem: while the shutter is open, the eye piece is closed. (I assume this is to prevent light from entering through the eye piece and messing up the image.) So I found myself guessing where the subject was as he moved.
Has anyone tried this technique and have any tips?
