Agfa Variomat
The Agfa Variomat was an exposure frame for the photo laboratory . With it, the exposure of the photo paper in the positive process could be automated for the first time . For this purpose, it had a built-in light meter in the housing . An elaborate circuit of electron tubes and relays switched off the darkroom lighting and at the same time switched on the enlarger . If the device was carefully calibrated, the Variomat automatically switched off the enlarger again and switched on the darkroom lighting after the correct exposure time had been reached .
In its time this represented a revolutionary relief and the most modern state of the photo laboratory technology. The model Agfa Variomat C was already suitable for the Agfacolor positive process - the processing of color images.
The trademark was registered in 1954.
