Abstract: A process for high resolution high accuracy photoreduction of radiographs, a rotatable photographic copy stand for the photoreduction process, and a high resolution high accuracy microfilm reader with built-in measuring capabilities are shown. The photoreduction process employs a camera with high precision optics, a high resolution copy film, and a first developing solution containing 0.014 to 0.025 moles per liter of a 3-pyrazolidone as the primary developing agent plus a lesser amount of a secondary developing agent, in a reversal process, to yield positive image having gamma values of 1.00 to 1.05. The copy stand has multiple workstations mounted on a rotatable frame, and several lightboxes.
