Personally, I have had the good fortune of always being able to do what I wanted, never working for others. Maybe it is a silly principle, but the idea that no one can buy me is important for me. I refuse assignments, even for projects that I have decided to do anyhow. It is somewhat the same with my books. When my first book, the one on the gypsies, was published, it was hard for me to accept the idea that I could no longer choose the people to whom I would show my photos, that any one could buy them.
