open and closed framing

FORMS, OPEN AND CLOSED styles of graphic composition.

OPEN FORMS tend to emphasise looser, less controlled positioning of elements in the frame as if they were unplanned, extending beyond the boundaries of the frame as though the camera just discovered them. Open form compositions are characteristic of documentary films, accounting for their reputation as being more realistic.

CLOSED FORMS tend towards self-contained compositions carefully arranged to include everything of importance within the fram.
