“A photograph may speak to the photographer's envy or disappointment just as much as it may reveal his anger or disapproval. And even if a photograph records a joyous occasion, behind it there may still be more than a small measure of heartbreak on the part of the photographer. A small measure of heartbreak? One might think such a thing is impossible--if your heart is broken, then surely it is broken completely. Yet the truth is that we can live with a minor fault-line in the heart--most of us do, in one way or another.”
