" For me the camera is a sketch book, an instrument of intuition and spontaneity, the master of the instant which, in visual terms, questions and decides simultaneously. In order to "give a meaning" to the world, one has to feel oneself involved in what one frames through the viewfinder. This attitude requires concentration, a discipline of the mind, sensitivity, and a sense of geometry. "
