Randomness: Clicking long exposure photos

I take photos in my free time, which is during weekends. I always enjoyed taking long exposure shots(with a shutter closing time of 1 second and more) at night time, to get those beautiful light trails of vehicles and starry street lights and smooth clouds at night.
After joining 500px.com, I had seen some amazing pictures of the seas captured in long exposure. After seeing those pictures, I too felt like capturing some long exposure shots at the beaches in Chennai and it was fun :-).

Here are some long exposure images captured at various parts of Chennai.

Note:

To get shots like these, you will need to use a shutter speed of at-least 5 seconds.
Which means you have to use a tripod to keep the camera still.
Now, even if the camera is on the tripod, the camera will shake when you press your camera's click button. Which will lead to slight blurring. Even the minutest of shakes can lead to blurring of some object in your photo. So use a cable release for a shake-free shot. It is a wired remote, which has a click button. A DSLR camera has slot to attach the cable of this remote to the camera.
These cable releases are available in any shop which specializes in cameras
