Quotes from others about the person
Petr Tausk said of Sever's photography, "The unique work of Jin Sever was strongly influenced by the surrealism with which he came into touch with regard to his predilection for French poetry. Sever made from his images of various 'objets trouvés' closed cycles showing his admiration for the hidden poetry in the real world."
