Troubleshooting Mamiya C330: Part 2

I previously described my efforts to troubleshoot some vertical lines showing up on the negatives taken from my C330. Suspecting problems with the reel, I shot a second roll of Tri-x, all frames of the same scene. When I loaded the film for developing this time, I reversed the direction of the roll so that it loaded frame #1 first.  You can see the results here:

Frame #1, loaded onto reel first.

Frame #12, loaded onto reel last.

This time, there was no difference in the frames; the vertical lines showed up equally in both.  Back to the drawing board, although I still suspect reel issues. The next time I load onto the reel, I'm actually going to do so upside down and see if that makes a difference. If it does, I will have solved my problem. If not, then it really is back to the drawing board.

Which brings me to my last point: Even though I've narrowed it down to a developing issue, there's still the nagging feeling that's not it. I don't get this problem with my Zero Image pinhole, although it's been several weeks since I've used that camera. In Part 3 I'll show the results from upside-down reel loading and discuss some next steps from there.

  1. Change tank and reels. Sell or give away the first. Or M80 it, July 4th around the corner.

    1. Ha ha...Actually, my last resort will be to use a steel tank that I've never used.
