Photography is unlike any other art form. In the other arts there is always a continuous interplay between the artist and his art. He has the painting or sculpture before him. What we have tried to do is to provide a medium for "artistic expression" to anyone with only a reasonable amount of time. By giving him a camera system with which he need only control his selection of focus, composition and lighting, we free him to select the moment and to criticize immediately what he has done. We enable him to see what else he wants to do on the basis of what he has just learned.
