"Documentary Film is a broad category of visual expression based on the attempt, in one fashion or another, to document reality. Knowledge comes in different ways through our five senses. Hearing, watching, touching, smelling & tasting are the only doorways to the outer world. The wise men say that if something is not truly experienced with all our five senses, the experience will be partial, not total. So in a way almost all our gained knowledge through life is partial." topdocumentaries.com
