Below texts came from the website of Henri Cartier Bresson, the great photographer.
Those words are so meaningful and beautiful, I have to record it here and read repeatly.
"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.
To take a photograph is to hold one’s breath when all faculties converge in a face of fleeing reality. It is at that moment that mastering an image becomes a great physical and intellectual joy.
To take a photograph means to recognize – simultaneously and within a fraction of a second– both the fact itself and the rigorous organisation of visually perceived forms that give it meaning.
It is putting one’s head, one’s eye, and one’s heart on the same axis."
