Salt Prints on Expired Glass Plates
Glass Plates In a past post I explored salt prints on expired 4x5 film. I thought this technique should apply to old glass plates. I had experimented in the past with glass plates in the darkroom to various success. I had some old Air Ministry plates from the Second World War which were fogged nearly to blackness. These would be good candidates for experimentation. Air Ministry Plates Box Clearing the Plates My first attempt resulted in a lot of learning :).
