eranasoulin Posted January 9, 2019 Share #1 Posted January 9, 2019 Advertisement (gone after registration) Hi all, I have a problem with some of the photos from my Leica CL/Leitz Minolta CL (M-Rokkor-QF lens). About a third to half of the photos have this strange faint (and sometimes darker) black shadow. It's always in the same spot at the top of the photo and it also shows on the negatives/slides. Does anyone have any idea what could be causing this? Is this some sort of fogging maybe? Or a light leak? Thanks, Eran. Welcome, dear visitor!

Advertisement Posted January 9, 2019 Posted January 9, 2019 Hi eranasoulin, Take a look here Leica CL - What is this faint black shadow line on top of my photos/negatives?. I'm sure you'll find what you were looking for!
plaidshirts Posted January 9, 2019 Share #2 Posted January 9, 2019 Form the uniformity of it, it looks like the film is not aligned correctly with the lens. Since the top is dark, the affected area would be the bottom after the film is loaded. Could the pressure plate be off? It may have been pushed up and not getting the bottom edge down flat as it can be. I don't think it's due to fog because the delineation is so clean. It's not a light leak either. Those will look like light streaks and won't be darker than the rest of the exposure. Have you had the same problem with other film? It could also be just a defective roll. And there's always the possibility the lab did something too. Sorry, I couldn't be of more help, but I hope you find the culprit. Quote Link to post Share on other sites More sharing options...
TomB_tx Posted January 9, 2019 Share #3 Posted January 9, 2019 (edited) The CL uses a vertically traveling cloth shutter, moving top to bottom. Perhaps the first curtain stops with a bit still above the edge of the gate, so it leaves a shadow. Look through the back while operating the shutter on B to check this.

I've had the same problem with a few different films (both colour and black and white), and it's always the same dark line. Sometimes it's a bit wider than other times. I didn't think about the pressure plate being off. I'll check it to make sure. Before shooting this roll I had the camera CLA'd, so I'm hoping I can fix this without having to send it back.

I'll check out the first curtain. Though I'm not sure what it's supposed to look like when functioning properly. I'll try find some photos of the inside of the camera.

In B setting, after you've pressed down on the release and are still holding it, look for the first curtain when it goes down and see if it goes all the way. You shouldn't be able to see any part of the first curtain sticking out. If it is, the part that's out will be blocking the film, which would explain the dark line.

I just did that and I couldn't see anything obviously sticking out. Either way, I sent it back to the person who did the CLA, so hopefully he can fix this.

samueltlogan Posted June 4, 2020 Share #9 Posted June 4, 2020 Hi all, I have a similar problem with my digital 262. What ever happened with OP? Did the CLA fix the issue? Welcome, dear visitor!

jaapv Posted June 4, 2020 Share #10 Posted June 4, 2020 I rather doubt that you'll get your answer here. This is a forum for analog cameras and the thread is about a film CL. I would suggest that you ask your question in the forum dedicated to the digital M typ 262. Quote Link to post Share on other sites More sharing options...

I'm not sure I've seen it happen on a Leica/Minolta, but it was a known issue with the Contax rangefinders (II and to a lesser degree IIa), as well as their russian clones (Kiev 4 etc.). Basically what happens is, as the first curtain travels down at speeds, it hits the bottom a bit too hard and bounces up a little bit, meeting the second curtain and closing the slit before it finishes its travel, thus not allowing enough exposure in a thin strip at the bottom of the negative (i.e. the top of your photos as we view them). This usually happened at high/top shutter speeds. Is this the case with you as well @eranasoulin? Also can you confirm that this exists on the negatives too, and not just the scans?

adan Posted June 5, 2020 Share #12 Posted June 5, 2020 You have flare (foggy yellow patch from sun outside the picture area) - but part of the image is being protected from the flare by the shutter tunnel , which produces the unflared dark stripe. It is not a repairable or adjustable fault, simply how spill light can reflect inside the camera normally. Use a (better) lens hood - or recompose so that the sun is farther away from the picture edge. On 6/3/2020 at 10:42 PM, samueltlogan said: Hi all, I have a similar problem with my digital 262.

samueltlogan Posted June 5, 2020 Share #13 Posted June 5, 2020 Thank you. It's only happened once. I am using the 50 lux. Not sure if I had deployed the hood. Relieved to hear it's not a mechanical problem Quote Link to post Share on other sites More sharing options...
