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.
After studying biology and medicine, Remmes did his medical doctorate in 1986 in neuroradiology, and became a consultant radiologist specialized in cross sectional imaging. He was awarded a Graduation in Professional Photography by the New York Institute of Photography.
Remmes' first photo exhibition "Operaria" at the University of Düsseldorf presents a portrait of backstage operations of the Deutsche Oper am Rhein. Remmes worked at various European opera and ballet theatres such as the Teatro Regio of Turin, the Graz Opera, the English National Opera in London, the Savonlinna Opera Festival in Finland and at the Chang'an Grand Theatre in Beijing, China. In 2002, the Theatre Museum Düsseldorf established the „Remmes Collection". Remmes was elected a Fellow of the Royal Photographic Society (FRPS), Fellow of the Royal Society of Arts (FRSA) and a Fellow of The Royal Society of Medicine. He represented the City of Düsseldorf at the World Exhibition EXPO 2010 in Shanghai, showing his work in an exhibition on the interface between theater work and theatrical stage art in Liu Haisu Art Museum Shanghai
