Automatic-Exposure Control for a High-Resolution Camera

Photography of distant objects requires accurate exposure to achieve maximum contrast with high-contrast emulsions. The autoexposure unit described in this paper has been designed for the ROTI Mark II tracking instrument to provide the necessary control. A pair of graduated neutral density disks is used to vary the light level at the film plane. By maintaining full aperture, maximum resolution is achieved for all light conditions.
