If the chemistry is right between star and photographer and the geometry of the pictures pleases the star, often the two people end up with a long-term professional friendship during which they continue to work together and to produce highly personal images.

What drove me and kept me going over the decades? If I had to use a single word, it would be 'curiosity.

A studio session ... provides the greatest chance for control. Even though there is total freedom, I still dislike studio photography and the contrived images that usually stem from this genre.

If the photographer is interested in the people in front of his lens, and if he is compassionate, it's already a lot. The instrument is not the camera but the photographer.

I can't hold a camera anymore.

Recording sessions were stimulating to photograph, because everything was in motion: the subject, the musicians, the technicians and the photographer. You needed fast reflexes to keep up with moving targets, and sensitivity and skill to get the pictures while keeping out of the performers' eyeline so as not to break their concentration.

I realize that I had the best of serious picture journalism.
