Using information provided earlier about their weekly routine, the photographer will arrive on the scene, and unseen, take shots of the subject. The subject will be photographed walking through the streets, going about their daily business. Without posing and artifice, the camera captures only the natural beauty of the person.
Andrew Hearst calls it "surveilling yourself".
