Keeping your shutter open for an extended period or time has both its benefits and drawbacks in photography.
While it can be difficult to work with a long exposure without a stabilization mechanism such as a good tripod, and you do have to consider the possibility of overexposing the image to the point of a completely blown out shot, this approach can produce some really artistic and eye catch results as well. See the examples below.
Effective usage of long exposure:
Exposure: 117.4 sec – Vehicle lights on a busy road.
Beautiful stars in the night sky.
Colorful, artsy image with interesting background.
Beautiful misty appeal to a shot of a waterfall.
Jouster on horse in an image intended to show motion.
