Since Philippe mentioned it, IIRC the Antwerp photography museum has some exquisite daguerreotypes on display... the Charleroi one never stroke me as something really worth visiting, although things might have changed since I was there... at least the director has changed, for sure... for the one that was in charge back then was really incompetent...

But I thought that you were looking for something contemporary, avant-garde, new... not museum pieces or old and widely known work by established artists...
