Since 1994, photographer Ari Versluis and author Ellie Uyttenbroek have been documenting the striking similarities in how people dress and express themselves in cities across the globe—Rotterdam, St. Petersburg, Zurich, Milan, Beijing, Rio de Janeiro, Casablanca, Praia, New York, Bordeaux, London and Paris. In a typological framework, they present each of their subjects against a white background, creating a scientific approach to street photography that seems to subvert the iconoclasm of the genre as a whole—a style that critic Gil Blank termed "August Sander and Eugène Atget turned on their heads by Bernd and Hilla Becher." Originally published in 1995, revised in 2013 and again in 2015, this final collector's edition of 'Exactitudes' includes more than 200 series of their signature grids, including the 19 additional works that Versluis and Uyttenbroek produced on the 20th anniversary of the project.
