The world today has been conditioned, overwhelmingly, to visualize. The picture has almost replaced the word as a means of communication. Tabloids, educational and documentary films, popular movies, magazines, and television surround us. It almost seems that the existence of the word is threatened. The picture is one of the principal mediums of interpretation, and its importance is thus growing ever vaster.Today the challenge to photographers is great because we are living in a momentous period. History is pushing us to the brink of a realistic age as never before. I believe there is no more creative medium than photography to recreate the living world of our time.Photography gladly accepts the challenge because it is at home and in its element: namely, realism - real life - the now. In fact, the photographic medium is standing at its own crossroads of history, possibly at the end of its first major cycle. A decision as to which direction it shall take is necessary, and a new chapter in photography is being made - as indeed many new chapters are now taking the place of many older ones.The time comes when we progress, must go forward, must grow. Else we wither, decay, die. This is as true for photography as for every other human activity in this atom age. It is more important than ever to assess and value photography in the contemporary world. To understand the now with which photography is essentially concerned, it is necessary to look at its roots, to measure its past achievements, to learn the lessons of its tradition. Let us briefly span its beginnings - they were truly spectacular.
