Jim Goldstein writes,
Employing long exposure photography techniques is a great way to create an image that makes others go “Wow!”. If you’re unfamiliar with long exposure photography the major ingredient needed is low light conditions, which will require your camera to expose for longer periods of time. In fact it’s even possible to use filters to reduce the amount of light that comes through your lens so as to produce long exposures even during the brightest times of day. Long exposures enable photographers to create an abstracted or surreal visual experience as opposed to reproducing a scene as we might see with our naked eye. In this regard long exposures allow you to artistically create something from a subject or scene that might otherwise seem ordinary with more standard photographic techniques.
