In Germany, Katharina Sieverding is considered a pioneer of an art that utilizes photography without overemphasizing its mimetic capabilities. Instead, she concentrates on the process, and her works refer more to the registration of light on the film than to the documented subject matter. It may be a coincidence, albeit not an extraordinary one, that five of the exhibited pieces depict the artist herself; the self-portrait does, however, constitute one of the most frequent motifs in her oeuvre. Transformer, 1973, the oldest piece on display, consists of several superimposed versions of her face.
