you should try the "cotton candy" effect some time, simply find a stream or something, then set your shudder speed so you can hold it open for like 20 -30 secs. You will need a tripod or something to keep the camera steady...experiment with the length of time and the the moving water will have a cool natural effect....you can also point it up at the sky, and leave the shudder open for a long time and capture the movement of the solar system...use less time and capture moving cars at night...also very cool...nice pics....keep sharing I love photos
