Mostly I take photographs in times of research. Whores' Glory was shot in 30 days, 10 days for each segment, but the research for each part lasted a couple of months.

Prostitution will always exist in every society, so I believe in a fair trade. Open the doors for women to earn their money without having pimps. The worst thing is to criminalize it, because then you open the doors for pimps, criminals, and trading.

I've made many documentaries, but prostitution was the hardest in terms of gaining the trust of the people being filmed.

Sometimes the presence of a camera is like opening a door, because many people want what Andy Warhol called "15 minutes of fame." But prostitutes don't want that.

On one hand, they [prostitutes] don't struggle because it's simply their life. In Mexico and elsewhere, once they get out of these places [brothels] they have a pretty square life.

If you connect with someone just once, that's something. But if you can connect twice, that's something else.

It's interesting because the Thai king says there's no prostitution in Thailand, it doesn't exist, so the prostitutes don't pay taxes. They can work other jobs if they want and put away money, maybe leave when they're 40.
