Karl Maria Udo Remmes (born 2 July 1954 in Tübingen, West Germany – 25 November 2014 in Köln) was a German photographer and physician. He has become known especially for his work in backstage photography specializing in opera, ballet and musicals. The leading idea of Remmes' photographic work is not the documentation – he wants to capture the moments when the hard work of acting transmutes into art.
