Look at the things around you, the immediate world around you. If you are alive, it will mean something to you, and if you care enough about photography, and if you know how to use it, you will want to photograph that meaningness. If you let other people's vision get between the world and your own, you will achieve that extremely common and worthless thing, a pictorial photograph.
Paul StrandThe portrait of a person is one of the most difficult things to do. It means you must almost bring the presence of that person photographed to other people in such a way that they don't have to know that person personally, but that they are still confronted with a human being that they won't forget. That's a portrait.
Paul StrandThe documentary photographer aims his camera at the real world to record truthfulness. At the same time, he must strive for form, to devise effective ways of organizing and using the material. For content and form are interrelated. The problems presented by content and form must be so developed that the result is fundimentally [sic] true to the realities of life as we know it. The chief problem is to find a form that adequately represents the reality.
