This is a wonderful artcle on creating your own time lapse setup (especially since you will hardly find a mitchell or leave alone an intervalometer in Mumbai).Read here.
If your curiosity has been piqued, try your hand at time-lapse photography. All it takes is a digital camera (consumer cameras work fine) and a method for exposing a frame on an interval. The Canon Powershot line of consumer cameras, among others, has a built-in interval timer controlled from the camera's menus. With that ability, you don't need anything else except a tripod to take a series of time-lapse photos. Then assemble the frames into a movie using QuickTime Pro or the equivalent.
One note of caution: Beware of battery failure! A consumer camera will run for just a few hours on a standard battery. An external power supply is a necessary investment. Motorcycle batteries, for example, run a camera for several days without failing.
With the right vantage point, a time-lapse camera system, and enough storage, you too can make time fly with professional-looking results.
