Usually, we are viewing photos that capture a short moment in time, but these pictures are completely different. The intent of long exposure photography is to create an image that highlights the effect of passing time. There is no fixed definition of what constitutes "long" because a 30-minute picture of a static object might not be distinguishable from a short exposure. Therefore, the inclusion of motion (mostly through light) is the main factor that adds intrigue to these images.
Bored Panda has compiled a list of interesting and innovative examples of long exposure photography. It will not only please your eye but give you some ideas about what to look for when trying to achieve a similar effect as well. From traffic lights on an empty street to fireflies in a jar, the photographers behind these shots certainly found an interesting way to picture their objects.
