I bought a second Hasselblad 201F with film back recently.
Something weird happened in my tests, and I can’t figure out what happened.
Besides doing a roll all shot with new body with new back (which turned out fine), I did combinations of new body plus old back and old body with new back to check for light leaks in new items. I know my old body and old back do not have leaks.
I did two rolls where I was switching things around.
In the first of those rolls, I took my old back which had four shots taken on my old camera and put it on the new camera. The first frame (#5) shot on new camera (with old back) was way overexposed. The image was just slightly visible on the right side of the frame, the rest of the frame was basically white. There were also flashes of light on the top and bottom in area around frame on left side. The rest of the frames shot with old back on new body were fine (6 through 12). So it was just the FIRST frame after old back put on new body that was extremely overexposed.
Then for another roll, I shot the first 10 frames with new camera with new back. Then I moved the new back to my old camera. In this case, it was the LAST frame shot on the new camera before new back was moved to old camera that was overexposed. Again, the image barely visible, mostly white. No white in the border this time. The remaining two frames shot with new back on old camera were fine.
The common denominator for the overexposed frames is the new body. In one case, it was the first frame shot on new body after a back attached. In the other case, it was the last frame shot on the new body before back taken off.
Frames where I shot something black with combinations of new back/old camera and old back/new camera were fine. No light leaks. And, as I said, the roll I shot all with new camera/new back (no back changes) was fine.
It’s possible I didn’t wind film to next frame before moving backs. But that shouldn’t matter either, should it? Of course, the dark slide was on backs when they were moved.
I’ll attach a sketch of what happened in case what I described isn’t clear. Also scans of parts of contact sheets with overexposed frames. In first, overexposed frame is frame number 5. In second, overexposed frame is frame number 10.
I’ve been using Hassy’s for years and have never had this problem when moving backs to a different camera. I wonder if there’s something wrong with the new camera, or if I just did something wrong in my rush to do the tests.
Thanks.
