发明名称 High contrast, photography and printing - has image splitter for congruent negatives with high intensity and low intensity
摘要 <p>The prismatic image splitter (3,4) is adjustable on the enlarger so that its separation can be adapted to the partic. separation produced by the camera. This allows the enlarger to be used in conjunction with any image splitting camera. The prisms are positioned between the objective and the film and can include integral filters. The two congruent images are exposed alongside each other. One image is filtered and records the detail in the lighter parts of the scene while the other image records the detail in the shadows. The combination of both images provides detail over a wide range of contrast.</p>
