Dark-room methods of enhancing details in diabetic fundus photographs: a preliminary study.
A technique for the photographic pre-processing of fundus pictures prior to computer image storage and analysis is described. Contrast enhancement of small details proved to be possible using normal photographic equipment. It is suggested that this method of enhancement may be particularly suitable for the analysis of diabetic changes.
