Film For Digital Cameras

In an optical camera the details of the picture are captured in an intricate pattern of light sensitive grains embedded within an emulsion that forms the traditional camera film. Each grain undergoes a chemical change when it is exposed to light. This chemical change makes the grain visible in the final print. In a small print these individual grains appear to merge together. However, the density of these grains affects the quality of an enlargement as the bigger the enlargement becomes the more noticeable the grain becomes.In a digital camera there is no film but the equivalent of the chemical grain is the picture element, commonly known as a pixel.
