The first frame shows a corridor and a black light switch. A woman walks into the frame from the left, into the corridor, and then returns ... The stain on the wall, meaningless figure at first hand, gains meaning little by little. The space is constructed with a pronounced depth, with a foreground and a background, and with doors that lead to spaces beyond the frame. The small, black square which serves as the focuses of the image, captures and fixes the viewer's gaze all the more because no sound disturb him. The figure breaks our concentration on that black stain. She is the disturber of the peace of the classic composition.
