In order to give an image a stop-action look, I learned you need to use your camera’s sports/action mode (indicated by the running figure on the basic shooting mode dial), or your shutter-priority mode to set a fast shutter speed. In this mode, denoted by the Tv (time value) or S (shutter) mode on your shooting dial, you set the desired shutter speed and your camera will automatically set the aperture to get the best exposure. I also learned that panning requires shutter to be 1/30th of a second while freezing action is 1/1000th of a second.
