The Douglas Historical Society, AZ, has a large collection of GPNs. A volunteer photographer digitized a large sample of them by placing the negatives on a small light table, using a camera stand to mount a digital camera and photographing the negative. The photos are then reversed in Photoshop. This produces a superb image. Our photographer-consultant said this was the preferred way to digitize GPNs. He used an on-line resource to produce a bound book of the most interesting photos we can display.
