New m3 problem Not a M3 mystery solved.

[Radost]

Hi I just purchased an M3 that has I believe a shutter issue. any help?

Strap in front of the lens?

If it were a shutter problem then the unexposed would be vertical, not horizontal.
If it were developing, then it would not have the edge marks so clear..
So looks like something obstructing the frame.
assuming we talking about a Leica M3.

 

[Radost]

Leica m3. Just purchased it. It does not look like a chem problem because of the clear markings at the end of the film. I checked the shutter when I purchased it looked fine.

 

[Radost]

The only thing is I did ecn2 before a week ago and I don’t remember if I cleaned the jobo. But I washed the film for a long time.

 

[awty]

There's only two possibilities that I can see, an obstruction which would need to be at the top of the camera frame, which would be very noticeable or something went wrong while developing, not sure what, looks like half the film wasn't submerged in the developer, even has a wavey line consistent with that....except for the edge markings are developed.

Jobo rotation impossible to get this development sideways.

I rolled another 15 frames and will try again.

 

[mshchem]

Yep, try another roll. I doubt it's chemistry.

 

[Radost]

I tried another roll. Looks better. No dark lines, some light leak around the sprocket.
Run a film from my Minolta A7. Perfect.
I think I did not clean the jobo after the ECN2 and something might have cross contaminated.

Good to hear you found the issue.

Possibly that was the problem. its a mystery

 

[Radost]

Just taught of something. Is it possible to be airport scanner? I shot the film at 1000 iso and flew through a very small airport

 

[koraks]

Is it possible to be airport scanner?

No, that would have created fog. You've got pretty much the opposite on your film.

 

[Radost]

No, that would have created fog. You've got pretty much the opposite on your film.

So I might have used the same stop bath that I used for ECN-2 chems…
Dont know if this is the reason….

 

[koraks]

It isn't.

If chemicals are the problem you wouldn't get the frame numbers 33, 33A, 34, etc. developed either because they also need developing and fixing. Do you have a strap on the camera, if the answer is 'yes' that is probably the cause.

Not a strap. don’t have a strap. Look at the line at the top of the frame, WHat caused that?

The problem is, no one can say. The shutter in an M3 is a horizontal-travel cloth shutter - when things go wrong with it, it does not produce film that looks like that. Development problems don't selectively develop certain parts of certain frames and not others - you may get a bit of mottling if there was some incorrect stuff in your tank, but it would quickly disperse into the volume of developer you pour in. Stop bath doesn't erase film.

The missing parts look like lens obstruction. The dark line on the opposite side? No idea.

You mentioned light leaks around sprocket holes - that should be pretty much impossible in an M3.

 

[Radost]

It turned out it is not the camera. The other rolls I processed were good.
I think the leak at the beginning of the film sprockets is because of me using a lead extractor with a bulk cassette. Next

 

[mshchem]

Back in the Instamatic days one's finger could cause this sort result. Camera and lens so small it was easy to obstruct.

Even that consistent black line ?

 

[MattKing]

Even that consistent black line ?

The black line is most likely from a light leak.
The clear parts of the negatives are most likely from an obstruction.
Perhaps that roll was hexed?

It should be sacrificed. Burn it.
