A PHOTOGRAPHY exhibition featuring the works of three contemporary German photographers is being held at the Sheung Wan Civic Centre. The exhibition, called ''Photo Works by Rudolf Bonvie and Astrid Klein and Truce by Michael Schmidt'', is jointly organised by the Urban Council and Goethe-Institut Hongkong. The exhibition hours are 10 am to 7 pm daily. Admission is free. Works selected for the exhibition are being shown in Hongkong for the first time. The photographs bring out different emotions in viewers. The three photographers started their careers in Germany and have unique working methods. Rudolf Bonvie has been working with photography since the mid-1970's. He won a scholarship for Contemporary German Photography in 1982. Some of his works on nuclear destruction, which display vivid imagination, will be featured in the exhibition. Astrid Klein won various scholarships and prizes in the 1980's. Unlike Bonvie who usually takes the photographs which he uses, Astrid always proceeds from the research of available photographs and pictures. ''Title'' is an essential element in her work. Michael Schmidt is a self-taught photographer who has been taking photographs in Berlin ever since 1965. He is the founder of the ''Workshop for Photography'' at the Adult Education Institute. Schmidt is also a teacher and a writer. The exhibition will run till April 23. The works of Michael Schmidt will be moved to the Ngau Chi Wan Civic Centre for display from May 1 to 11.
