There will come a day when memories become the most precious thing we have, more than objects, more than words. They will be the place to which we return to recognise ourselves, to rediscover who we have been and who we have loved. On that day photography will be our silent companion: it will not speak, but it will know how to tell everything. It will hold our hand through time, giving back faces, gestures, moments that we believed far away. And in a shot we will rediscover not only the past, but the profound meaning of what has stayed with us.
