All the good pictures that came so easily now make the next set of pictures virtually impossible in your mind.

I can think of numberless males, from Bonnard to Callahan, who have photographed their lovers and spouses, but I am having trouble finding parallel examples among my sister photographers. The act of looking appraisingly at a man, making eye contact on the street, asking to photograph him, studying his body, has always been a brazen venture for a woman, though, for a man, these acts are commonplace, even expected.

Unless you photograph what you love, you're not going to make good art.

Like all photographers, I depend on serendipity, and when you're photographing children there's often an abundance of it. I would have an idea of what a photograph would look like and then something would happen - a dog might lumber in and become a critical element. I pray for what might be referred to as the angel of chance.

There's always a time in any series of work where you get to a certain point and your work is going steadily and each picture is better than the next, and then you sort of level off and that's when you realize that it's not that each picture is better then the next, it's that each picture up's the ante. And that every time you take one good picture, the next one has got to be better.

I don't see many artists who are not trying to bring their work to the public - -to the contrary I see artists nearly desperate to get attention for their art and, failing that, often for themselves.

As ephemeral as our footprints were in the sand along the river, so also were those moments of childhood caught in the photographs. And so will be our family itself, our marriage, the children who enriched it and the love that has carried us through so much. All this will be gone. What we hope will remain are these pictures, telling our brief story.
