When using slow shutter speeds at night, a camera can record patterns of moving lights that can’t be seen by the eye. Cars and amusement park rides are excellent subjects for this technique. To capture the blur of moving lights, it’s best to set up a tripod at a location where you can get a great view of your subject, and where the ambient light is not too strong. You’ll be using long shutter speeds of about 5 seconds on up to about a minute.
