Ancient technology took eight hours and more to capture the first images. Louis-Jacques-Mande Daguerre is considered as the indenter of photography as we use it today. The former models of camera used a light sensitive film role to capture images. But today number of images with unbelievable resolution could be digitalized in a fraction of a second. Along with the computer revolution, photography also became digitalized and more sharp, high resolution pictures could be captured, stored and modified with modern digital cameras. World today passes through a digital era, and photography also moves along with this digitalization. Camera manufactures compete each other to add more and more features to every product thus adding advantages to camera users.

How does your digital cam work?
When you take a picture with a digital camera the light strikes a digital sensor array. These digital sensors resembles computer chips. The digital sensor is made of millions of tiny sensor points called "pixels," which is short for "picture elements. A camera with six mega pixel resolution means an image will have six million light dots in it. Greater the pixel rate higher the resolution and clarity of the image. When the image strikes the sensor, it gets all those mega-pixels excited. First the image goes through color filters above the individual sensors. The sensor converts the image from light waves into an analog electrical signal.
The analog signal is then run through an analog to digital converter where it becomes a pure digital signal. Then it is again put through a series of electronic filters that adjust the white balance, color, and aliasing of the image. Next a compression cycle makes the image as small as possible by dumping unnecessary pixels, for more efficient storage. The image is then transferred into a temporary storage area or into a memory card.
Now let us see few of the advanced digital cameras available in the market:
