This was one that was easier to do back in the film days (film images do not have noise), but it can be done with a digital camera by stacking several shorter duration exposures to get one long exposure. Have you ever seen a photo of a waterfall where the water looked white and fluffy? Ever seen a photo of a road where the light of the cars going past are streaked, like a river of light? Those are two examples of long exposures. It is hard to do this with a digital camera because, generally speaking, even with low ISO settings, they start generating artifacts (noise) after about 30 seconds. While this will work fine for waterfalls, for many other types of subjects, 30 seconds is kind of on the short side for long exposures. To shoot waterfalls, one of the first things you are going to want to get is a neutral density filter. This will reduce the amount of light entering your camera and allow you to take a longer exposure. The next thing you are going to want (for longer exposures) is a cable release. You are not going to want to stand there with your finger on the shutter button for 10, 15, or 20 minutes, and a cable release will allow you to lock the shutter button down for the requisite amount of time. Of course a tripod is an absolute necessity, because you will not be physically able to  hold a camera steady enough to take long exposures.

Next, you will want to find a good subject, and a good position to shoot from. If you are living in a city, the top of any tall building at night will do. Put on your neutral density filter, put the camera on the tripod, set the shutter on B and the aperture on f/8 or f/11, aim, focus and shoot. The brilliantly lit buildings will look like islands of light in a river of flowing light. Waves breaking on a shore might be another good one. That would look like masses of cotton candy all along the shore. Stars are always good. Those are all clichéd though. The fun part comes when you can use your imagination and think of other things that might look nice when shot this way, and that no one else has tried. That will give you a sense of accomplishment that you won't believe.

Another cool use for long exposures: emptying out tourist attractions of annoying tourists. Of course, you may end up needing to use exposures even longer than 20 minutes, but it's a pretty cool trick.
