Christy Turlington

I remember doing a shoot for Herb Ritts, hanging off the Eiffel Tower - that wasn't your usual day at the office. It was terrifying, and in the end, you couldn't really tell how high I was because the photographer was scared of heights, so he was quite far away from me.

There have been so many photographers and editors who mentored me over the years. At the very beginning, the person who taught me the most was Arthur Elgort. I always loved working with him. We traveled a lot together.

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.
