'Tough' meant it was an uncompromising image, something that came from your gut, out of instinct, raw, of the moment, something that couldn't be described in any other way. So it was tough. Tough to like, tough to see, tough to make, tough to understand. The tougher they were the more beautiful they became.

I have to say, taking photographs is such an instantaneous act. The recognition and the acting on the recognition, depending on your equipment, is close to instantaneous.

When you're on the street, and, as you're walking along, a woman turns the corner going away from you, and for an instant you have a glimpse of the side of her face, of the gesture of her shoulder, the shape of her body, and you are committed... You are in love for an instant, or your senses are rocked for an instant. That person then disappears and is lost to you forever.

It comes down to risk, again and again. If you risk coming out, if you risk making pictures that aren’t good, you might discover something in a photograph that is the key. The very doorway to your own interest.

Making any statement of your feelings is risky. It's just like making pictures.

You look at it [a photograph] and all around the real world is humming, buzzing and moving, and yet in this little frame there is stillness that looks like the world. That connection, that collision, that interfacing, is one of the most astonishing things we can experience.

I photographed the entire thing in color because to photograph it in black and white would be to keep it as a tragedy. Because there is a tragic element to photographing, in this case not war, but the collapse. It was just destruction.
