For whatever it's worth, all of the shots posted from Saturday's shoot with Bud at Grand Haven were taken on Provia 400F slide film. I was shooting with an 80-200 mm lens and was shooting in the shutter "S" priority mode, letting the camera adjust the aperature. The shutter speed was between 1/400th and 1/500th of a sec for all of these shots and I was using autofocus, although the waves sweeping across the pier occasionally drove the autofocus in my camera "wacko" for a few seconds.
