ANP says World Portraits is a fair trade photo collection of people from around the world. The people you see in WP photos are not professional models but ordinary people who sign a model release contract on the spot. Their photos are taken with no make-up or staging. Every time his photo is sold, the person in the photo receives a royalty (details here).
ANP can do this because of the backing of the DOEN Foundation, who supports the WP concept. Dutch Princess MÃ¡xima recently launched World Portraits in the Museon in The Hague.
