Long exposure shots of traffic
I always had this fascination of taking a picture of moving traffic with a long exposure(So that the tail lamps of cars appear as continuous streak of red light) in the dusk. I had no idea how it was taken and used to think that this might be some 'magic camera trick'. But obviously its not a magic trick.
All you would need to take such a long exposed shot of traffic are
1. A camera where you can set really long shutter speed.
2. A stable surface to keep the camera(preferably a tripod)
3. Optionally(also preferably) a remote control for your camera.
Chose a good spot and set up your camera. set your shutter speed to say 10 seconds. take a picture. Dont go too high on the ISO(over 400), for issues with noise. Also try to reduce your aperture(means increasing the f/number) so that you would not get over exposed images. Also in theory, making the aperture smaller(Increasing the f/number) would increase the depth of field and hence get a sharper image of the vehicle tail lamp streak.
You are all set, just go ahead and start clicking. Change your shutter speed based on the natural/artificial light available.
The picture you see was taking in Denver at a traffic light. I love the quality in this pic simply because it was not shot using my SLR but with my canon powershot A710 IS and still pretty good.
I would be uploading one similar pic with my SLR and lets see how muc of a difference would the pic be!
Picture details:
Camera: canon powershot A710 IS
ISO: I am actually not sure, it does not show up in the pic now!
Shutter speed: 8.0 sec
Aperture: f/8.0
