Velvia 50 development problem ?

[Paul Ozzello]

Can anyone tell me what happened to this roll of Velvia 50 ? The lab claims my roll of 120 wasn't sealed tightly enough. But it doesn't really make sense as the problem is worst at the beginning of the roll (and closer to the center of the spool).

Well if the roll tried to unwind you can see something like this happen I suppose. Had a case were a roll from my adapt-a-roll 620 tried to unwind on me, but I don't think that this was it.

Those marks look too regular, like sprocket marks. You don't suppose some fool tried to process it like 35mm through their machine do you? In that case it might be from bending of the film base causing marks. That would, naturally make it their fault, but again naturally they'll never admit it.

That wouldn't explain this kind of defect.

I think they're right...

I think they're right..

But then wouldn't it get worst approaching the end of the roll? It's actually the opposite : the problem is really bad at the beginning and there are barely any blue spots at the end of the roll.

The lab processed it manually in a tank I believe.

I've processed a reasonable amount of E6 film in my Jobo and haven't seen this defect before, or anything similar with negative film, any light ingress associated with "fat rolls" has shown up at the end of the roll as you reference. - I do try and carry a roll of electrical tape to deal with occasions when I might not be 100% convinced of light tightness but don't recall having an issue with the Fuji self-seal approach.

The lab processed it manually in a tank I believe.

- as in by hand with inversion? - this seems like a slightly strange approach for E6 or C-41 for that matter.

Depends on when the problem happens - when loading the roll into the camera, or when unloading it from the camera.

I've done a few loose rolls in my time, doesn't look at all like that.
Looks like some mechanical fault.

What a beautiful panoramic. Its a shame about the dev problem, Have never seen anything like it in the years Ive self-dev'd 120 film

I might be wrong about the specifics but the lab told me they process B&W and E-6 "manually".

That was a lab I went to in France to avoid taking my films through the airport scanner. I took them to my trusted lab in Montreal and they said there was no way it was from a loosely wound roll. On two other rolls there were spots from chemicals that has sprayed onto the film so I'm concluding it wasn't the photographer ;-)

Thank you. From what I can tell someone at the lab didn't know what they were doing.

Agreed. I would be furious if a lab destroyed an image like this of mine.

The regular nature of the marks makes me suspect a mechanical issue of some kind with the lab's development, but what exactly I couldn't say.

at least we live in the modern era so you can repair it without the difficulties you may have encountered 10 or 30 years ago.
YMMV

It would still be a nightmare to correct in Photoshop.

IDK. just takes time and a light touch. .. I had to reconstruct old silver gelatin tintypes from 120 years ago once
and these days PS is pretty powerful. ...

I sadly agree.

Thankfully it was only a test roll and my remaining films were developed back home. What irked me more was the lab telling me it was my fault... It's a pretty easy fix in photoshop but luckily I also shot a version on Portra 400 so all is not lost.

These sorts of problems are one aspect of why I prefer to process my own colour film.
