Marjatta Oja's practice-based doctorate in fine arts includes an extensive theoretical publication Sculpture between the Artist and the Viewer. The art of Marjatta Oja employs moving images, racks or stands, mirrors and projection materials to explore the dispersing of images in space and the new situation this gives rise to for the viewer. One of Oja's aims is to map the spatial boundaries of the moving image. She also has a holistic interest in the process of art making, starting from the studio. She wants to construct a ‘multi-situational' research-like process in which the viewer does not identify merely with the finished piece, but also with the possible states of mind experienced by the artist while making the work. At the end of the publication, Oja presents a selection of photographs of her works, as well as conclusions, in which she reflects upon the methodology and key goals and results of the research.
