An amateur photographer originally trained in the sciences, Henneberg came to the medium from his study of physics, chemistry, astronomy, and mathematics. His knowledge of the technical aspects of photography served his aesthetic interests particularly well, as he created gum bichromate prints that involved multiple stages of development. The resulting prints possessed a rich, engaging texture that augmented a satisfying spatial sense, as in this landscape-Henneberg's favorite genre.
