Abstract
n spite of today's emphasis on electro-optic imaging, film cameras continue to be used in overwhelming numbers in the tactical air forces of the world. All indications are that widespread deployment of E-O cameras is still several years away. This makes improvements to the performance of film cameras desirable and even, in many applications, necessary. Film camera performance has recently seen dramatic improvement both in image resolution and system reliability. Film magazines with direct-drive metering rollers have been developed and placed into operational inventories to improve film velocity control and reduce self-generated motion disturbances. This paper describes the changes and addresses the resulting levels of improvements.
