Andreas Feininger's latest book on photography (see Successful Photography, Successful Color Photography etc.) presents sound guideposts for the artist-photographer and categorizes the aspects of the photographic medium that make it unique- both in itself and in the many purposes it has. At the outset he states his principles of photography: that it is a universal language and an art with which humans can translate the meanings of reality. Covering the scope of photography then leads Feininger to comment on the many kinds of picture taking there are- utilitarian, documentary, creative- and their branches, but more important are the necessary traits of a good photographer and a good photograph. Not easily definable, these nevertheless arrange themselves into basic categories. For the picture there is its stopping power, its impact, its graphic qualities. For the photographer there must be the initial spark of interest that engenders a strongly personal way of seeing things plus technical skill which perfects the end result. Discussing these principles helps in the broader determination of good picture taking and in the study of some famous photographers and their work and the theory of the picture story. Invaluable for any amateur or professional who wants to think photography through all the way.
