Strange 'Photo Plus' results...

[Peter G1G2]

Hello all,

Just came back from Berlin.

Had a wonderful time with my new MP (and my wife).

Did 9 rolls, all turned out fine, except for the 'Photo Plus 200' I thought I might try... (penny wise, and pound foolish?)

Please take a look at the screencapture below.

I've never before seen this. It's all over the negatives...

Question:

Is it:

- the film?
- my beloved MP?
- me?

Thanks in advance,

Peter

The film or an Xray machine, although I doubt the latter at 200 ASA.

Looks like you got light into the film canister.

looks like light leak from shutter to me, of course might be wrong . I'd check if the shutter curtains stay closed when you re winding shutter, x-ray hypothezis is possible, at certain angles x-rays leave similar pattern click

Thanks,

Dunno about x-rays. I had some 120 xrayed (forgot about it in checked baggage) and the pattern was basically a sine wave through the whole roll. The wave pattern varies I guess depending on the orientation to the xray but it should still look like a wavy line.

This theoretically could still be from an xray but I like the shutter theory although you'd think all the rolls would have this line if it was the shutter. Did you have to pass by any other scanners or detectors when you went to Photo Plus ?

Look at your negatives, if the light streak (looks dark) extends into the film sprocket area, you can eliminate the shutter as the cause. I have had film canisters leak at the gate and where the metal caps meet the body, causing similar streaks. In this case, the streaks get a little closer together toward the end of the roll. If the lab loaded your film incorrectly into their machine, this could also happen, usually fogging one or more frames at the beginning of the roll.

Because the streak is perfectly vertical, that would seem to rule out the x-ray, and point towards a shutter problem. However, some frames have TWO streaks of "light", seemingly ruling out a shutter problem. And since the "streaks" are not in sthe same spot on every frame, it does not seem to indicate a light leak. But it must be one of these!!??!!. Was the film in checked luggage or carried on board the cabin?

 

[Windwalker57]

As film is rolled onto the spool, each turn gets just a little longer, thus if it is exposed to light while wound on a spool, the streaks will appear at different distances from each other, most noticeable at one end or the other. Peter G1G2, do the edges of the negatives also have streaks?

Yes, this is true. But if it is a light leak the spacing of the streaks could indicate where the leak happened, as you imply (in the camera or in the film cassette) I never heard of this particular film but if it's a "budget" film perhaps they use cheapo casettes. So given it only happened to this one film, and considering the placement of the streaks, Windwalker could well be correct. Much will depend on this qustion about the streaks being on the edges of the film or not....

 

[Peter G1G2]

Thanks for the replies, guys.

The edges are uneffected.

I posted the same question at LUF and I think the verdict - shutter or X- ray - is not out yet... :bang:

I can't rule out X-Ray problems; I just realised this particular roll was in the camera when we went through security visiting the Bundestag...

I would rule out shutter problems because all your other 8 rolls came
out fine. The Bundestag visit explains it, their Xray machine might
not comply to airport standards ...

Peter:

This is exactly what happened with my new MP. It's not x-ray exposure but is the shutter not capping when you wind the last partial frame. When you wind the shutter and film on the last frame and if won't wind to a complete frame that you can expose then rewind the film the shutter doesn't cap properly and there's a small slit that allows light to strike the film. Your film is EXACTLY what happened to me. It only happened some times and was only when the camera would'nt wind the last full frame.

I sent it off for warranty repair and received a confirmation last week. Leica said 4-5 weeks for a repair.

I never had this happen with any of my other earlier M's but it appears to be more common on MP's.

PS: I work with x-ray photograph all the time and this is not x-ray exposure. These shutter problems have to start somewhere and the previous 8 rolls may have been during th eperiod prior to the failure. I shot a few hundred through mine before it started.

 

[Windwalker57]

This would also account for the fogging/color shift on the whole roll.

Thanks for the reply.

Your explanation sounds very plausible to me. Would this mean that if you put the lenscap on, and rewind in the - relative - dark, this problem can be evoided?

Kind Regards,

Peter

@ x-ray:

it was roll # 3 out of 9...

All others were just fine. It happens quite often that on the end of the film I can wind only hafway... So how come I got 'lucky' on the other rolls? I never use a lenscap.

Peter the same thing happened to me. Only a roll here or there had this problem. I actually tried to make it happen by taking the lens off in bright sun light when I would rewind but never made it happen. It was a ramdom problem.

Magus there is a potential for any of the M's to do this although I have never had it happen i 40 years with a couple of dozen bodies.

I think the stripe happens when I would stop rewinding and reposition my fingers on the spindle to make another turn of the rewind spindle. With a crank like the M7 or M6 the rewind is one fluid motion without hesitation at a given spot. I also don't think the gap in the curtain is wery wide so not much light passes through. It might not happen in dim light and be more of a problem in bright. One other member of RFF had this happen on his MP. It might just be a problem in the MP's.

Yes if you put your lens cap on when you rewind you'll have no problem but the camera should'nt do this and Leica will fix it.

Magus this is why I've been bitching about quality controll in newer leica lenses and cameras. I've never seen this happen in previous generation cameras and the lens issues I've had and currently have have not happened in previous generations to the 80's vintage and newer lenses.

Hopefully you'll not see this in your M6 and if you have a new MP keep your eyes open to this problem. Three of us on here have had it happen.
