In 2001 Plamper produced the colour series ‘Uniforms Amsterdam’ and in 2004 she photographed ‘Uniforms Berlin’ for the German paper ‘DIE ZEIT’. The ‘Uniforms’ series shows double portraits of people once in working and once in private clothes.
Photographs from this series have been selected for the traveling exhibition ‘Zeichen. Sprache ohne Worte’ and are shown at Haus der Geschichte Bonn, at Zeitgeschichtliches Forum Leipzig, at Kulturbrauerei Berlin and at Musée d’Histoire de la Ville De Luxembourg (2011-2016).
The series ‘Uniforms’ includes about 40 double portraits which can be ordered on large size for exhibitions and sale.
