A digital representation is a symbolic representation of information. An analog representation is a representation that uses a physical model of the information to be represented. Writing is digital because it is symbolic. The word "tree" is not a physical model of a tree; it's just a symbol that stands for a tree. Film photography is analog because it is a physical model of the image being recorded; the film emulsion contains a model, in the form of more-or-less dense areas of silver or dye, of the light distribution in the original image. -- Anthony
