Hello! I bought a used Nikon F80 (N80 for Americans) from a local camerashop a little over half a year ago now and have been having issues with the negatives from that camera. On the negatives, there are thin, straight horizontal lines that go across the frame. But here is a little more background to that... Initially, I thought it was just residue or something or other from scanning, but I later looked closer at the negatives and found it embedded onto the negatives. So, I did some online research and figured it may have been the lab I'd been using. With that information, I decided to try another lab. Same issue. So then I thought, maybe there is a tiny dust particle causing this issue. Still, I figured it'd be best to go to the camera shop that I bought the F80 from as they should be pretty knowledgeable just to be sure. So I did, and the person there too thought it may be dust, so he did a thorough cleaning right then and there of the interior of the camera. He then put in a roll of Fuji Superia to test out if that worked. It did not, so the only other thing I was told it could be was the back pressure plate on the door of the camera. In order to do that, I'd have to give my camera to the store, and they would in turn send it to a local repair shop to get the plate replaced. I accepted that and did not have my F80 for about a month as a result. I was excited to get the camera back and immediately put in a roll of film and went about shooting. Yesterday, my film was done being processed by a local lab and scanned in the negatives at home (yeah yeah, I'm no purist). At first, no issues. However, by the fourth or fifth frame, I noticed the stupid horizontal line popping up again! I decided to call that same camera shop and see if they could offer me any help on the matter. In a nutshell, they said that as they aren't the repair shop, we can't know for sure, but we can send it back for a re-repair. But I'm questioning what good that's going to do. Should I even bother with this camera (which I've grown to really enjoy)? Should I just replace the F80 with something else (then again, the same problem could appear on another camera)? Because you guys seem to be quite experts on analogue photography, do you guys think there is anything else that could be wrong that could be fixed? Also, on a related note, I was hoping to begin processing my own film soon. While that would just entail develop only, down the line I may want to dabble in darkroom printing, considering the perceived higher quality of doing so (plus it just seems like a magical experience). With that, I'm assuming these lines will appear on a darkroom print as they would on a scanned negative. So is there any way to remove these lines safely on already processed negatives? P.S. I forgot to add that I noticed there was some dust on the interior of the camera, including on the pressure plate, and cleaned it off. Could it just have been that? Thanks for any and all help, APUGgers.
