The Begining…

Its hard to make a start, especially when you don’t know what you want to start. Nevertheless, I am convinced that I have made an interesting start. Ever wondered how we capture beautiful pictures of those things we like, with just a click of a camera? Yes, the first things that come to our mind are the lens and shutter. While lens keeps the image focused and sharp, the shutter has a bit peculiar role to play. The shutter has to open and close in a jiffy to ensure that the CCD sensor/array is exposed to the light just for the right amount of time, large enough duration so that the light from the picture makes an impression on the sensor, and short enough duration so that it avoids capturing the motion of the objects in the scene which could result in smearing of the picture.
