We had a video shoot on the Wolf River (near Fremont) yesterday afternoon.  Always great fun to do shoot some video with old friend and to make some new friends.  Did a bit of still photo action shots along with the video and I will post them later this week.  The keys to this shot is a very high shutter speed to freeze the action and a smooth panning motion to reduce any camera shake.  The consequence of the high shutter speed is you need to shoot at an open aperture to avoid excessive ISO noise.  Focus precision becomes critical at the open aperture because the depth of field is so small.  Skill is good but a little bit of luck also helps!
