The actor and director's daughter, Marin Hopper, said Wednesday of the exhibition at the German capital's Martin-Gropius-Bau: "It's a visit with him. It's like being with him - it's a very intimate experience seeing the photographs."
The black-and-white, small-format photos were taken between 1961 and 1967, when Hopper was out of favor in Hollywood and before he directed "Easy Rider." The prints were selected by Hopper for an exhibition in Fort Worth, Texas, in 1970.
The prints - some now showing signs of wear - were found among Hopper's belongings after he died in 2010.
