I'll try posting a pic with this old d---tal camera off the light table. At first I thought it was fog across the entire area but the image area is not fogged. This seems to tell me that although the image is very faint at the top of this pic where the background sweeps up ( I'm not sure you will be able to see this from the photo) that although the image is not being registered since it is behind the rails the gap from the slop in the film rails and septum is allowing light to reach the edges of the film that is being pushed back against the septum (at the top) since the bottom of the film is sagging forward against the film rails. Keep in mind this is an 8x20 negative shot in the vertical position. I will post a pic taken with a 2MP camera. Robert
