发明名称 Method and apparatus for making photographic prints from negatives
摘要 The present invention concerns a method of making photographic prints on stock from negatives that differ in density range. The appropriateness of the exposure gradient of the stock for the particular negative is ensured by employing stock with a definite "contrast-Schwarzchild-effect" and by so varying the intensity of the light that the negative is exposed to during printing that the gradient is adapted to the characteristics of the particular negative as a function of the accordingly varied printing time.
