Abstract

In recent years, techniques of obtaining astronomical imagery have been experiencing a conversion from traditional photographic emulsions to electronic arrays as the detection devices of choice. In spite of the great promise of linear scanners and area arrays, using CCDs or photodiodes as detectors, this transition has been evolutionary rather than revolutionary. Indeed, for many large volume applications, such as sky surveys, the photographic emulsion has remained highly desirable not only as the detector but as the archiving and display medium as well.
