How to Capture the Motion of Moving Water in Photography
A slow shutter speed will need to be chosen to show the motion of the water. The slower your shutter speed the greater the motion captured. I suggest you experiment. After a shot immediately check the results on your LCD screen. Then adjust, to a slower or faster shutter speed, until you get the shot you want. To achieve optimum results will require a shutter speed of at least 1/15 of a second, or longer. Truly smooth water should be captured if you leave the shutter open for over a second.
