Horizont...this one's got me stumped!

[Matt Fattori]

Hope someone can shed some light on this. I've been shooting a Horizont swing lens camera for a few years and have had it cla'd and seals replaced not so long ago; it's been fine until very recently. I just developed the last two rolls that have been through it and discovered this bizarre artifact on every frame as if the film is lifting away from the film plane at the end of the lens circuit. Here are a couple photos of the negatives and the camera.
Any insight is much appreciated.

Thanks,
Matt

You gave the best explanation for this artefact yourself:
Film being "loose" at one side of the frame.
I don't know whether such is technically possible, but it completely explains the artefact.

You did not load film properly. Just follow picture attached to inside of the film chamber.

 

[Matt Fattori]

I suppose that's possible, even likely, though I have been loading by the same method without trouble for several years. I'm trying to visualize how this would recur precisely in every frame and can't see it.

 

[Matt Fattori]

Well, I just loaded a new roll and immediately realized I'd neglected to go under the first bar on the last roll. I suppose pulling the film across the back has become automatic since I've started shooting more 35mm cameras.

Thanks for sorting me out gentlemen,
Matt

It happens! Just enjoy taking that new roll knowing that is loaded correctly.

I did the same thing with my WideLux when I had not used it for a long time. By the way to avoid banding shoot the camera a number of times without film to smooth out the lubrication before loading the film, if the camera has sat for a long time.

This can be said for any camera.

Ah, but more so with rotating lens cameras which are susceptible to banding.

 

[AgX]

You are right, banding is more visible than for instance a unprecise leaf shutter.

Banding is very rare with Horizont unless you accidentally touch with one of your fingers rotating drum on the top of the camera, but again, with Horizont you can expect everything. They are amazing cameras when they work properly (as with any other camera). I absolutely LOVE them all! Old (metal ones), 202s and S3s.

Thats normal- I have my own rotating panoramic camera-forum at delphiforum all about the Horizon and widelux problems-mostly.

banding resulting from light-leak.
similar overexposure with too slow rotation at start with widelux 1500 and widepan 140(despite smaller image-110 versus 122mm) at 1/250. thats why we dont have that in Horizon 205 PC with its 1/60 and slower exp. times.
but with 202 also a lot of banding-problems. my repair-man had to rebuild-adding a new drum.
also reflexion-problems.
widelux 1500 was badly built- first batch. then improved. with widepan 140 everything was better(w1500-copy)
only noblex was the best short-rotation pancam. with also some disadvantages. had one of the first for long testing-could compare with w1500.
from horizons 35mm format: S3pro was best if only they would have used the old lens. the new "better" lens gives unsharp results at full stop-down at f16. reported endlessly. comparison indoor shots gone in pbase. yes i had filmrail-shim to get better DOF. it was at 5m and showed clearly image of S3pro is not as sharp as from 202. inspected with 30x loupe. in 12x print maybe one cannot detect the failure. but the large size 24 x 58mm is made to be enlarged big.
