Working with Light
Although nighttime is always dramatic, be careful when composing your shot, so large areas of black sky and land don't overwhelm your picture. Many "night" shooters, however, actually prefer twilight - the magical time between sundown and darkness in which land and sky take on dramatic tones and multiple colors. Another twilight benefit: A brighter sky means an overall brighter scene - less of the dark vs. light extreme that makes nighttime metering a challenge.
To achieve the slow shutter speeds that produce a real feeling of movement, you'll need late-day conditions (sunset, twilight, or nighttime), a low ISO, a small aperture (large f/stop number), and a tripod or other support to keep things steady. If possible, fill the image with the subject, since the closer you are to a moving object the easier it is to show motion.
Rides and compositions vary, so to achieve the desired effect, you might want to experiment with different shutter speeds. A good place to start is in Aperture Priority mode: Set your lens at the SMALLEST aperture (biggest f/stop number), which will automatically result in the slowest possible shutter speed for the given ISO and light level. Then try another photo or two with slightly larger apertures (thus, resulting in faster shutter speeds).
