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 involved in what one frames through the viewfinder. This attitude requires concentration, discipline of mind, sensitivity, and a sense of geometry. It is by economy of means that one arrives at simplicity of expression.
