First few photos are on high shutter speed. The water looks great at slow shutter speed. High speed or Action mode will take away the beauty of flowing water.
had to shoot at higher shutter speeds coz most of these were at 300mm and the subjects were not stationary. and it was not flowing water - this was in a lake !!
