Title: Werner H Holle: Innovator in Photographic Technology
Introduction
Werner H Holle is a notable inventor based in Wetzlar, Germany. He has made significant contributions to the field of photographic technology, holding a total of five patents. His work primarily focuses on improving exposure control mechanisms in photographic cameras.
Latest Patents
One of Holle's latest patents is an apparatus for storing a voltage analogous to an exposure parameter in photographic cameras equipped with an electronic timer and electric exposure measurement. This invention features an analog-to-digital converter as the storage unit, which includes a digital-to-analog converter. The output voltage from this converter is compared with the voltage delivered by the exposure meter. When the voltages are identical, the analog-to-digital converter is stopped, and the remaining voltage controls the exposure parameter in the camera. Another significant patent is an exposure control device for photographic cameras. This device utilizes electronic means to create a voltage analogous to a diaphragm setting based on the luminous density of an object, film sensitivity, and preselected time. The device includes a diaphragm path meter that operates simultaneously with the diaphragm, ensuring precise exposure control.
