philipus Posted November 10, 2011 Share #1 Posted November 10, 2011 Advertisement (gone after registration) Hi I'm not sure this should be posted in the Film forum so, Moderators, feel free to move the thread. I use an M3 with a 50mm Summilux LTM. On a few images of the last rolls that I have scanned, there is what looks like a light leak on some photos. Mostly, in the right-hand part of the image but sometimes on both sides. And on at least one below more in the middle of the image. I will post a few more photos in a new post. These light problems are on the film itself, ie it has nothing to do with the scan. I guess in theory it could be the lab but i doubt it. What could cause this? Cheers and thanks in advance for your help Philip Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

stunsworth Posted November 10, 2011 Share #3 Posted November 10, 2011 Looks like a shutter problem to me - there's uneven movement as it travels across the frame resulting in an overexposed vertical strip. Link to post Share on other sites More sharing options...

philipus Posted November 10, 2011 Author Share #5 Posted November 10, 2011 Thanks Steve. And Mauro (sorry I posted at the same time). If it were the shutter wouldn't more than just the odd photo be affected? cheers philip Link to post Share on other sites More sharing options...
TomB_tx Posted November 10, 2011 Share #6 Posted November 10, 2011 I'd guess a shutter brake problem. With the back open, trip the shutter. Are the metal ends of the shutter curtains still visible at the edge of the frame, or are then fully past the edge? Both my M6 and M4 developed this issue eventually, and after repair the ends of the curtain then went fully past the frame. I found the light leak affected frames that were left for some time with the shutter closed. If I wound the film immediately after exposure, no leak!

stunsworth Posted November 10, 2011 Share #7 Posted November 10, 2011 Advertisement (gone after registration) It's likely to be caused by one of the shutter curtains sticking, it may be that it doesn't stick for every exposure. Link to post Share on other sites More sharing options...

andybarton Posted November 10, 2011 Share #9 Posted November 10, 2011 If it were the shutter wouldn't more than just the odd photo be affected? cheers philip It might just be at one or two speeds. Link to post Share on other sites More sharing options...
duckrider Posted November 10, 2011 Share #10 Posted November 10, 2011 might ther be a light leak from the back side cover? Tape back side with black isolation tape & take some pics. is the M3 a double stroke model? If so, that might be the reason for the overexposure in the middle of the image, cam was only stroked once and stored for a while? good luck Thomas Link to post Share on other sites More sharing options...
earleygallery Posted November 10, 2011 Share #11 Posted November 10, 2011 If it's NOT the shutter the overexposed 'lines' or 'strips' (call them what you wish) will be visible on the film beyond the image area. It definately looks like a shutter issue to me. Link to post Share on other sites More sharing options...
stunsworth Posted November 10, 2011 Share #12 Posted November 10, 2011 Well, whatever the cause it needs to be sent for repair - with some sample photographs to help the technician. Link to post Share on other sites More sharing options...
mikebidwell Posted November 10, 2011 Share #13 Posted November 10, 2011 Well, whatever the cause it needs to be sent for repair - with some sample photographs to help the technician. Certainly agree with this but suggest you make sure you send both negs and prints. Best wishes Mike B Link to post Share on other sites More sharing options...
philipus Posted November 11, 2011 Author Share #14 Posted November 11, 2011 Thanks everyone for your quick and very informative replies. I appreciate your help a lot. I'd guess a shutter brake problem. With the back open, trip the shutter. Are the metal ends of the shutter curtains still visible at the edge of the frame, or are then fully past the edge? Both my M6 and M4 developed this issue eventually, and after repair the ends of the curtain then went fully past the frame. I found the light leak affected frames that were left for some time with the shutter closed. If I wound the film immediately after exposure, no leak! After tripping the shutter, the metal end of the shutter is visible on the left side of the frame. This happens on every speed (see pic below). Is this abnormal?? I find it interesting what you and Steve write that it might not happen for every exposure, for instance, like you say, when the film hasn't been wound directly after a shot. I don't exactly remember after which photos I've wound the film directly and after which I haven't. I've noticed that it varies how I do it. Philipus, Will van Manen in Zoetermeer is your man. Thanks for this tip. I still have warranty on the camera so if that fails to cover the issue I will contact Will. I've heard good things about him from several sources. might ther be a light leak from the back side cover? Tape back side with black isolation tape & take some pics. is the M3 a double stroke model? If so, that might be the reason for the overexposure in the middle of the image, cam was only stroked once and stored for a while? good luck Thomas Thanks Thomas. Sorry, I should have said in the first post, the camera is a single stroke model. I don't think that there is a leak from the back cover because almost all photos turn out ok. It is only a few percent that have this problem. However, I will mention it as a possibility in my message to the dealer. If it's NOT the shutter the overexposed 'lines' or 'strips' (call them what you wish) will be visible on the film beyond the image area. It definately looks like a shutter issue to me. Good thinking James, thanks. I've looked again at the film strips and the "leak" doesn't extend beyond the photo. Certainly agree with this but suggest you make sure you send both negs and prints. Best wishes Mike B Thanks Mike. I will send in both photos and negs. Once again, thank you for your help. Phili Welcome, dear visitor!

TomB_tx Posted November 11, 2011 Share #15 Posted November 11, 2011 From your photo of the open back, the shutter curtains are stopping too early. The metal "caps" should have moved completely out of sight. It needs adjustment - most likely the shutter brake mechanism. Link to post Share on other sites More sharing options...
