Posted - Jul 22 2009 : 04:16:04 AM Hello Luiz, the optical path is different, but it is the same principle: the film is moving while the document is scanned. When using a rollover camera you scan manually, Jan III does it automatically. Regards, Detlev

Posted - Jul 19 2009 : 4:49:07 PM Hello Luiz, The rollover technique was not unknown to the west. Keith Melton shows in his book "Spycraft" an OTS (CIA) rollover camera from 1968. Detlev
