1) Busy making a prototype paper neg holder for my quarter plate camera. Using a commercial tin darkslide for the prototype. The focal plane is some 6mm above the rear flange on the camera so I've currently got some 2.5mm to play with. I can either stretch the neg bare across the window in the holder or I can install a 2mm glass plate to create a sandwich. I understand that the glass option was how this was originally done, with the neg between the glass and a backplate. Any views or suggestions? 2) Nowadays, does anybody use Gallic Acid in any part of the process? There seems to be a body of thought that it can be used at the end of development to enhance the blacks.
