Original: «A photograph is not a painting, a poem, a symphony, a dance. It is not just a pretty picture, not an exercise in contortionist tecniques and sheer print quality. I t is or should be a significant document, a penetrating statement, wich can be descibed in a very simple term - selectivity. To define selection, one may say that it should be focussed on the kind of subject matter which hits you hard with its impact and excites your imagination to the extent that you are forced to take it. Pictures are wasted unless the motive power which impelled you to action is strong and stirring». <br class="br">Fuente: Scala, Andrea A. L. About Photography. Editorial Lulu Press, Inc, 2014.
