Photo engraving - the process of reproducing pictures for printing - is another side in Johnstown's busy industrial field. The Conemaugh Engraving Company here operates one of the largest and most modern plants in the state. The above picture shows one of the first steps in the photo engraving process. The photo to be reproduced as a metal cut is recopied by this big camera to give it a screen (raised dots) for printing purposes. Adjusting the lens of the photo processing camera is Joseph Oravec, an employe of Ceco. This camera can make the reproduction three times as large as the original photo or reduce it to one-sixth of its size.
