Warning! Painful newb questions ahead. If that bores you, move along. Like the title says, can someone explain static versus dynamic action shots in relation to shutter speeds and aperture? I can get decent action shots in auto ("green box" mode) or in shutter priority mode, but I think if I understood the principles behind getting the shot I would be able to apply it to my camera better. Someone in another thread mentioned opening up the aperture to "smooth" out a water scene. That would make a more dynamic photo, showing motion, as opposed to a really crisp static photo. Right? I mostly take pictures of kid and my dogs and horses, so, lots of movement. I want to get nice crisp shots of the subjects, but not necessarily of the surrounding environment as well. I'm having a hard time finding the happy medium between that, and a blurred subject, or a totally static picture.
