Digital photography is a revolutionary new way to take pictures. However, it is very much based on traditional photography and uses many of the same principals. Both types of photography need a lens to focus the light and a shutter to allow the light to enter the camera. The difference between digital and traditional photography is how the image is captured.
Digital photography uses an electronic sensor to capture the image. The sensor is made up of millions of individual 'pixels' which convert light into a number. Rather than waiting for the picture to be developed, digital pictures can be seen almost immediately on the viewfinder of the digital camera.Traditional photography uses film which must be developed in a darkroom using various chemicals. The developing process produces 'negatives' which must be printed before you can see the picture.
Digital photograph quality depends a lot on how many pixels it has. The number of pixels is sometimes referred to as the 'resolution' of an image, and can be expressed as a dimension (800 x 600), or the number of pixels per inch. A common resolution for computer screens is 800 x 600 and this means the monitor can display 800 pixels from side to side and 600 pixels from top to bottom for a total of 480,000.
