Stop Motion is when the aperature is set really high so that when something happens, it is able to basically make it appear as frozen. This photgrapher did a great job of showing stop action. If you look, every piece of coffee seems as if it is stopped in mid air. I really like this photograph because it is unique from most of the other fotographs. Most photographers like to focus on water and common events, this picture is unique and you can tell that it had some planning involved as to how the coffee flew out of the cup like that.
