Agfa Variomat type 8627 The Agfa Variomat is an image frame for the photo laboratory. For the first time it became possible to automate the exposure of the photo paper in the positive process. It had a built-in light meter in the housing. An extensive circuit of electron tubes and relays switched off the lighting the dark room and at the same time the enlarging device. If the device has been carefully calibrated, the Variomat automatically switches off the enlarger after the correct exposure time has been reached and the darkroom light will be turned on. At that time it was a revolutionary relief and the most modern technology for the photo lab.
