Long exposure is one of the techniques that I find the most amazing. The way that the camera captures those few seconds and you're able to see it, is really amazing. Pictures like that got a special feeling, somewhat magical.
When an image is taken including stationary and moving subjects (for example, a fixed street and moving cars or a camera within a car showing a fixed dash-board and moving scenery) using a slow shutter speed, interesting effects, such as light trails occur.
Long exposures are easiest to accomplish in low-light conditions, but can be done in brighter light using neutral density filters or specially designed cameras. We'd love to see your pictures! Post them in a commentary! And don't forget to visit these photographer's photostreams! Cheers! ;)
