So I recently got my hands on an old Kodak Six-20 fold-out, and decided to give it a go. It takes 620 medium format film, but that's not available anymore, so you apparently have to buy 120 and then respool it. So, for my first roll, I respooled, shall we say, sloppily. For some reason, I decided that a combination of ISO 100 film and weak light would be somehow okay. Now, I'm guessing it probably wasn't.
I took the first roll in yesterday for processing, and I got a call that said the film was completely overexposed, with nothing recoverable, although some traces of image on some of the frames (and there were, apparently, distinct frames). The guy on the phone thought it was something wrong with the camera, because there were distinct frames. My thought, though, is that I exposed the film some when I was respooling, and then trying to expose the film normally exposed it even further (I was using Sunny 16 in broad daylight, or modifying it for shade and such, so I'm assuming my exposures were generally correct). Also, if it helps any, the film was Fujichrome Superia. Who do y'all think was likely right?
If it really could be the camera, then I should probably spend my next roll doing some controlled tests, to determine to what extent the camera's markings are off, if they are. But if it was just the spooling process, then I may as well just go on and shoot normally with the next roll (I've loaded another roll onto the spare spool, and this time I did it in an interior bathroom, with the door closed, at night. I could see a slightly less dark patch at the bottom of the door, but throughout the process I couldn't see anything in the room, the film included, so that should be safe, right?).
So, what do y'all think? Should I just go ahead with the next roll, or could it really be a problem with the camera? Also, just out of curiosity, does anyone know just how much exposure lattitude you get with these films?
I don't even get a viewfinder that can tell me focus: I get to focus by estimating distance to subject
