Donít be afraid to play with the shutter speed to create some interesting effects. When taking a night time shot, use a tripod and try shooting with the shutter speed set at 4 seconds. You will see that the movement of the object is captured along with some light trails. If you choose a faster shutter speed of say 1/250th of a second, the trails will not be as long or bright; instead you will freeze the action. This technique works well if you are using a tripod and if you are photographing a moving object.
