Abstract: The methods and apparatus disclosed herein provide commercially viable means to selectively improve the input and output characteristics of photosensitive materials, especially the output contrast variables. The present invention allows commercially available photosensitive material such as the high contrast Ilford Cibachrome Copy CCO Paper.RTM. to display dramatically improved color balance and contrast range characteristics when making reproductions from slides or prints. Recreational, professional and military photo duplication techniques are greatly improved by the present invention.
