I've been on a house cleaning kick lately. Not my domicile, but my computer. I've got thousands of images that I tucked away for that "someday" when I'll take them all out, dust them off and create the world's next great photo exhibit.
I've been ruthless, slashing and burning my way through them, after all, I have worked as a press photographer and know that, at best, only one image in ten is worth keeping, and that was in the film days. With digital, probably one image in one hundred.
But, once in a while, I run across one that stops me in my tracks and makes me think.
