Abstract
A new high resolution method of photographic image enhancement is described that uses induced fluorescence emission from the processed original negative image. The visible wavelength light flux emitted from each region of the negative is proportional to the silver density of the original negative, even at extremely low densities. The fluorescent light emitted can be detected, integrated, and thereby enhanced by many methods, including rephotography, fluorescence microscopy, or digital image processing methods. The fluorescence image enhancement method is nondestructive and applicable to both underexposed imagery and low-optical-density regions of properly exposed imagery.
