Photography is more than a means of recording the obvious. It is a way of feeling, of touching, of loving. What you have caught on film is captured forever, whether it be a face or a flower, a place or a thing, a day or a moment. The camera is a perfect companion. It makes no demands, imposes no obligations. It becomes your notebook and your reference library, your microscope and your telescope. It sees what you are too lazy or too careless to notice, and it remembers little things, long after you have forgotten everything.
