The exhibition, entitled ?Active Witness? brings together 27 works by photographers representing each member of the European Union.
The aim of the exhibition is not only to illustrate circumstances and issues of concern, but also to raise awareness of the importance of active participation and volunteering as a positive response, the organisers say.
Tamás Dezső?s photographs have been published in Time Magazine, The New York Times, National Geographic, GEO, Le Monde Magazine, Ojo de Pez and Polka Magazine.
