Abstract : This program has resulted in the development of a portable fluorescence image enhancement capability. The processing apparatus provides an advanced development model image enhancement kit suitable for field testing and technical evaluation. This instruction manual contains a detailed description of all aspects of fluorescence image enhancement and an illustrated step-by-step simplified procedure. Only tap water and receptacle voltage need to be provided by the user; all other apparatus and chemicals required to fluorescent dye tone black-and-white negative films are provided. The toned image can be directly printed using conventional methods to obtain 2 to 4 f/stops of effective speed increase. Alternatively, the fluorescent image can be excited with green light illumination (Wratten No. 55) and rephotographed through a red emission filter (Wratten No. 26 or 29) to obtain 3 to 5 f/stops of effective speed increase. The lower the fog level of the original image, the more successful the enhancement process will be. Very little enhancement can be obtained for original images having fog levels greater than 0.3 optical density units. (Author)
