Leica MP / Lightleak?


Recommended Posts

Hi,

 
I got these strange streaks on my images
Especially visible when shooting in portrait format and underexposing a bit.
 
I think development can be ruled out as the streaks are always on the same position (throughout various films) and the films are developed hanging in large tanks (don't know the english word for this).
 
First I thought that the scanner might be the problem, but also here the streaks stay in the same position no matter how I place the negative (90°, upside down etc.).
 
So my only conclusion would be that these are caused be lightleaks, but I can't really be sure how and where the light should get in (Leica MP).
 
Has anybody seen something like this before?
 
thanks,
 
daniel

If the problem occurs with short exposure times, I'd suggest having a look at the  edges of the shutter cloth. Are they uneven or "hairy"?

 

thx. didn't see anything.

but "cleaned" the edges anyway. 

put in a new film and did some test-shots against the blue sky with shutter speeds from 1/60 to 1/1000.

Looks more like a Dev or scanner issue to me. I would try a film from a different camera as the next step.

 

The scanner can be ruled out because no matter in what direction I "insert" the negative the streaks always stay the same.

Might try another scanner some time.

Development also can be ruled out because nothing touches the negatives during processing. only one small clip at the start of the film.

No rollers or anything else involved.

How do you agitate? Wrong or insufficient agitation can make these stripes. Not enough developer can also result in stripes.

 

You wrote that you underexposed the negative. Underexposing colour film may also cause stripes in the negative. The photo below is underexposed Ektar 100 and there are visible stripes in the image. I don't know exactly how much I underexposed, but it should be something around one stop.

Not developing myself (at least not color).

But though it may be possible to get streaks from agitation they wouldn't be in the exact same spot through different films.

 

My issues really seems to come from dirty or uneven shutter curtain "ends".

Same as e.g. here:

El Niño, this is as pop says muck on the rubber curtain edges. I had this on an old M6TTL. It is most noticed at fast shutter speeds as the gap is only 2mm at 1/1000th so any muck closes the gap making dark lines in the longer direction. As the shutter curtains overlap it is difficult to clean yourself. Probably a job for Leica?
