If photography was once for special occasions, today we have an astonishing ability to document every passing moment. That can, of course, be a lot of fun. If nothing else, the whole world now knows that you really do look different after a few drinks. But the ease of photography has also spawned an ambition to create a record of our lives that is roughly as long as our lives. If some primitives once supposedly feared that photography would steal their souls, today we fear that to fail to photograph is to lose something forever. But fighting time is a losing battle. The effort to record everything is vain and soon starts to feel empty.
