Paper Abstract

As part of an overall program to develop techniques for the intensification of severely underexposed photographic negatives, a technique involving the use of a scanning electron microscope (SEM) to scan the film and display the electron beam scattering intensity on a CRT was investigated. While the program was curtailed before the technique could be fully evaluated, the ability to enhance underexposed film by the equivalent of 5 stops a factor of 32 was demonstrated. This compares favorably with other techniques being investigated, such as autoradiographic sensitization. The SEM technique has the further advantages of being real-time, maintaining the high resolution of the original negative, and being nondestructive. In addition to the above mentioned application, this technique has promise as a convenient means of scanning photographic images for digitization and signal processing.
