Pictorial arts create their separate spaces with distinct features and relations to reality. The depicting space is two-dimensional and closed unlike the depicted space, which can be three-dimensional and open. A flat projection of a volumetric original is formed in a real object (drawing, painting, photo, etc.). This external model can be perceived as a separate object in its internal spatial image. However, the depicting space serves for evoking another internal model of depicted space. Both these perceptual images can relate in different ways. A viewer may concentrate on the picture’s surface or look as if “trough” it. Accordingly, the colour spots on a plane become either independent object of perception, or sensory material for perceptual image of depicted space. Relations between these two ways of vision are differently formed in art history. The picture surface can be treated more as a “wall” with some paints on it, albeit depicting something else. It can be interpreted also rather as a “window”, behind which another space is located. Thereby, various spatial codes can dominate in semiotization of pictorial spaces. Gestural, mimic, haptic, proxemic, object-functional, social-symbolic and other codes can be equally used to interpret depicted objects and things beyond them. The architectonic and synesthetic codes can dominate in interpretation of lines and colours on the depicting surface independent on their figurative functions. The perceptographic code mediates connections between depicted and depicting spaces, and the demarcation code regulates arrangement of frameworks separating pictorial spaces from space of viewers.
