As a popular hobby over the past 170 years, one feature that remained constant in photography is the need for a camera to be loaded with a film that needs chemical processing. In a traditional camera, the photographic film, a strip of plastic covered in chemicals that react when exposed to lights, is the crucial factor. In a digital camera, the place of the film is taken by a small chip called a CCD. CCD reacts to the light just as film does. CCD converts the light into a digital electronic form, instead of storing the image chemically which can be stored in a computer.
Computer programs can be used to sort digital images into an album on a personal computer (PC). Certain printers can directly be linked to the digital camera for making prints. Once this versatile piece of equipment is attached to a PC, one can open a world of photographic and artistic possibilities.
