                            Digital Camera

A digital camera stores an image digitally instead of recording it on film.

Once a picture is taken, it can be downloaded to a computer system,
and then manipulated and printed using a graphics program.
The biggest advantage of a digital camera is that it makes the creation of images inexpensive and quick,
because it does not require film processing.                                                                                                                                                                Type of Digital Camera                                                                                                                                                                                                                                 1.Professional Video Camera:-

These cameras specifically have multiple image sensors, one for each color,
which enhance the camera's resolution and color range.
Unlike conventional video cameras, they do not have built-in features like VTR (Video Tape Recorder) or microphones.                                                                                               2.Camcorders used by amateurs:-
