It is tough being patient when you are more than a half million dollars in debt.

The fact that a thirteen-year-old project still resonates and can still have a large exhibit with lots of newspaper, magazine and TV press shows the timelessness of the project.

Scientists are usually nice, organized, logical people who are very cooperative. I always learn a lot of science while shooting science stories and it helps to be able to speak intelligently to a subject about his or her field of work, i.e., do your homework before the photography.

We live in an idiotic capitalist self-indulgent society where the sex life of a pop star is more important than impending starvation, land mines and child soldiers in Africa, or more interesting than the world's biggest man-made natural disaster in oil fields of the Middle East.

I like to move as much as possible and look at reflections, weird angles, subjects from airplanes and cranes. I feel sorry for the Jabba the Hut types who can't do this. Once an obese student told me that he wanted to be a war photographer. I said, "Really?" and then I shot him.

Think about the photo you want to make beforehand. Then do it, but also don't be blind to better options that present themselves at the location. Be flexible, and be patient. Leave ego at home. Get the photo before you yell at the asshole, not after.

Before digital, I spent thirty years shooting color transparencies, which are very unforgiving of exposure. A half stop can make or break a good photo on slide film.
