This was taken after I made a fixture on which to rest my digital camera on the twin lens. The interior magnifier popped up so this is shot through that with only a small portion of the ground glass visible. The glass and magnifier are both very dirty but I think that could be a slight advantage as I could photoshop random spots out of each image. Or, I could clean it the best I can and leave the spots in every image much as Atget had his consistent negative holder markings. This will work itself out in time.
