Dutch photographer Arie Versluis, 1961, has been working on a series called Exactitudes together with profiler Ellie Uyttenbroek, 1965, since 1994. They have worked mainly in Rotterdam, but also in various other places. Drawn by the theme of social groups and dress codes they photograph people in the similar poses. The people are chosen on the streets by how they look and what they wear. After 16 years an archive has been build. The photographs have been published in a book, that every few years is revised and reprinted.
