Recorded images that are created as a personal or collective expression against political regimes during significant political changes are the counter-weight for those generated by the official media. The recorded document remains when the revolution is over and can often be interpreted not only by its content but also by the type of device used. On the more sophisticated level, video art and experimental cinema are continually using new approaches and forms of presentation. The viewer, shaken from accustomed visual habits, experiences new forms of perception and becomes more critical.
