supercrouton Posted May 22, 2018 Share #1 Posted May 22, 2018 Advertisement (gone after registration) M3 Horizontal light leak / streak? Help! :-) Greeting all! Attached are images from a '59 M3 seviced by DAG at some undetermined time before I bought it. This issue only occurred on this roll after 20+ previous perfect rolls. This horizontal streak showed up an most of the 38 exposures. It seems worse on longer exposures but is still visible on a few of the faster shutter speeds. It does NOT show at the 1/1000 range. The first two pics are from the first part of the roll, the third pic is from the end of the roll. Film: Ilford 400, lens Sumilux 50mm (with hood). Any help would be appreciated. If this symptom has been discussed and solved, let me know where and I will gladly delete this post :-) The scans just hit my email, and I have asked the lab to check the negatives' rebate to see if it was processing, since I do not have the negatives in hand yet. Many thanks, Dan. Link to post Share on other sites More sharing options...

earleygallery Posted May 22, 2018 Share #2 Posted May 22, 2018 Hi, My first suggestion was going to be to check the negs! Almost certainly not a shutter fault and light leaks are usually less regular. I’m guessing a processing or scanning fault. Link to post Share on other sites More sharing options...
plaidshirts Posted May 22, 2018 Share #3 Posted May 22, 2018 ... light leaks are usually less regular. I’m guessing a processing or scanning fault. I agree. My money is on scanning. My scanner did something like this before where it created a line when there wasn't one. Replacing it solved the problem. The intensity of light is too uniform and consistent to be a light leak imho.

adan Posted May 22, 2018 Share #4 Posted May 22, 2018 Could be a contaminated roller, if the film was machine-processed. A "deposit" of crystallized developer around a roller would over-develop a stripe as the film rolls over it. It is theoretically possible that a failed shutter light trap could result in light leaking "up" past the shutter, but 1) the marks are usually within a couple of mm of the edge, 2) usually have at least one "sharp" side and 3) would vary more with the intensity/angle of the ambient room light.

supercrouton Posted May 22, 2018 Author Share #5 Posted May 22, 2018 Thanks for the quick responses! The lab already shipped the negs, so were unable to examine them. I will check them myself as soon as they arrive. The lab say they will happily re-scan if the negs are clear. Either way I will post the results to hopefully help others with similar issue.

arnaud33 Posted January 26, 2023 Share #7 Posted January 26, 2023 Advertisement (gone after registration) Hi, I know this topic is quite old but I have a similar issue on my m4-P Had this light steak appear on a few exposures on most of my rolls for a while, quite randomly, usually high daylight conditions. Not the lens, as I have changed lenses and had similar issues in both. Have you found the source of the problem for yours? Arnaud Welcome, dear visitor!

Huss Posted January 26, 2023 Share #8 Posted January 26, 2023 It's one of two things: 1/ As light leak through the bottom hinge of your film door. Put a piece of masking tape over that to see if it makes a difference 2/ A flare from inside of your lens box (the area behind where the lens attaches to the camera). Perhaps a shiny/less matte area at the bottom? Remove your lens and take a look. I've received similar flare patterns with a Nikon F2, all to do with the angle of the light hitting the inside of the camera just wrong. Link to post Share on other sites More sharing options...

Happened to my m2-r but quite irregularly it didnt bother me for a couple of years, i shot plenty during these years however i got the chance to see out a local tech and spoke about it, he reported back, my leaks happened only after i cocked the shutter, which probably explained why it never always happened, sometimes it didnt happen since i only cock the shutter prior shooting it very thin leaks, light gathering, he sent me the video which showed it 1 Link to post Share on other sites More sharing options...
