One of the most basic, overlooked, and fun aspects of photography is that you have the power to slow time down or catch a split second.
One image happens so slowly that we could never see it and the other happens so quickly in real time that we would never notice it. Play with shutter speed!
Use a slow shutter speed and a tripod to make a pretty picture of any creek or stream. On the other hand, you can use a fast shutter speed (1/500 and up) to capture an object in motion.
Combining a fast shutter speed with a long lens, you sports buffs can get a trophy of your own when you are able to catch the expression on your favorite runningback's face as he slips past the final defense toward a winning touchdown. Remember, catching the moment in fast-paced action photography may take a little more practice so hang in there.
