I used a roll of TMAX 400 in a Leica R3 without batteries. I thought the exposure was adequate for the settings and everything sounded ok in the camera as i took the photos but when i processed it today, (D76 and Polymax fixer) i get NOTHING on the frames but a black line. Only a black stripe where the frame starts/ends but no image. I don't think it has anything to do with the way i developed it since i always do the same thing and it always works, so i believe there is an issue with the camera. When taking a photo the camera acts normal and the times seems fine so i wonder if anyone has encountered this before? Could it have something to do about the lack of batteries?
