As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! Just thought I'd post the above image in the hope that someone might be able to offer advice on the probable cause of what you can see happening in the lower RH corner of the shot. There were other images which exhibited the same problem albeit to a lesser degree on some other frames. In October the body was sent to Solms for investigation /repair and after 5 weeks was returned stating that the fault could not be found. On Tuesday we visited Bath and there I ran a 24 exp Fuji 400 ASA Superia X-Tra film through using a 50mm f/2 Summicron. This was processed the same day and after examining the negs & prints was a little dismayed to see the problem was still there. In fairness I contacted Leica CS and was asked to send it back to them for further investigation. It would be nice though to see if any of the Leica experts who use the forum could give a steer in the right direction, so if anyone has any thoughts whatsoever on what might be the cause feel free to let me know.

pop Posted December 8, 2011 Share #5 Posted December 8, 2011 The bright corner of the negative lies toward the top of the body on the left hand side (as seen from behind), i.e. it's the corner closest to the rewind crank. That's also where the light in the scene comes from. Link to post Share on other sites More sharing options...
earleygallery Posted December 8, 2011 Share #6 Posted December 8, 2011 What does the neg look like? Probably a leak coming in through the viewfinder area. Link to post Share on other sites More sharing options...
mikebidwell Posted December 8, 2011 Author Share #7 Posted December 8, 2011 Advertisement (gone after registration) What does the neg look like? Probably a leak coming in through the viewfinder area. Sorry for the quality of the scan but I wasn't sure of the best way to be able to show you. It looks as though there is a double image along the bottom of the neg but looking at the neg in question through a loop it perfectly clean except for the dark area which comes up on the print. if anyone can tell me how to scan the neg properly I'll do it.

adan Posted December 9, 2011 Share #8 Posted December 9, 2011 I would say the pink blob lower right is your large pink index finger sticking in front of the lens as it rests on the aperture ring or focus tab. Happens to me at times with certain lenses if I'm not paying attention. Notably the ultracompact medium wideangles (28/35 mm). The double images in the second scan look like reflections off the glass of a flatbed scanner - especially since you say they are not visible viewing the film iteself.

That was one of my thoughts, however I took particular care on this occasion to try to make sure this possibility didn't happen. The Lenshood on my 50mm Summicron which i was using was fully extended and at the time I pressed the shutter release my left hand was firmly holding the lower left hand corner of the camera so it could not be near the front of the lens..

What about your right hand - as I agree with Andy. That does not look like a light leak. Your fourth or fifth finger protruding when you press the shutter? I have done it and the results look exactly like that, and also had problems with wrist straps intruding into the frame. Link to post Share on other sites More sharing options...
250swb Posted December 10, 2011 Share #11 Posted December 10, 2011 As has already been said the pink area is the top left of the negative, not even on the same side as the hand that presses the shutter. So I go with the theory that it is your left hand, the one focsuing the lens or operating the aperture. A finger is partially getting in the way. If only you had obscured the image even more the solution would be easier to spot. Steve Link to post Share on other sites More sharing options...
pgk Posted December 10, 2011 Share #12 Posted December 10, 2011 Looks to me as though you have a light leak. The scan you show has enhanced this but if you correlate it with the original image posted it is clear that there is a similarly placed colour variation across the frame. It is an odd one but as a pure guess it might be in the region of the sprocket drive and so may be shielded by the sprockets as they engage - hence the odd unaffected patches. I'd also guess that its very slight and the effect depends on ambient light and how long the section of film sits on the sprockets - so you might find it variable depending on brightness and how long it is between exposures?

becker Posted December 10, 2011 Share #13 Posted December 10, 2011 as said before, finger on the front lense could be reasonable. kr matt Link to post Share on other sites More sharing options...

I'd also guess that its very slight and the effect depends on ambient light and how long the section of film sits on the sprockets - quote] It needs saying again, look at the back of your camera, the sprocket drive is on the right hand side of the camera. But the pink patch is top left, on the opposite side to the sprockets gears, you are forgetting the image is projected upside down in the camera.

adan Posted December 10, 2011 Share #16 Posted December 10, 2011 So why aren't they over the whole frame and is it merely a coincidence that they are worst where the problem shows most? In that second scan, the film is not in a carrier (since we can see the whole film, including sprocket holes and white background all around). Without a carrier or holder, the film has curved up at the bottom, so the bottom edge is separated physically and visually from the scanner glass/reflection, while the rest of the film is lying right on top of its reflection. The fact that the bar codes along the film edge are also duplicated show that it is an artifact of the scanning - no "light leak" or processing error would cause doubled bar codes, but a scanning reflection would.

mikebidwell Posted December 10, 2011 Author Share #17 Posted December 10, 2011 So why aren't they over the whole frame and is it merely a coincidence that they are worst where the problem shows most? In order to clear up the confusion regarding the sprocket holes shown in the first negative image I've just rescanned the neg using the film holder. This gives a better view of the neg and I've converted it to B&W. Welcome, dear visitor!

adan Posted December 10, 2011 Share #18 Posted December 10, 2011 I still lean to the finger theory - but it could, at least in this back/side-lit shot, be a flare patch from the sun. The 50 'cron gets a rap from some as being flare-prone, and the built-in hood is pretty small and ineffective. Depends on whether the other shots you mention were also back-lit from the left.

Hi Andy My original thoughts on this whole problem was what you said, however what is confusing me now is that with that thought in mind I paid particular attention to the way I was taking each shot. After focusing and checking the aperture setting I ensured that before I pressed the shutter release I made sure there was no way my fingers could be anywhere near the front of the lens and on every occasion the hood was fully extended and yet this shot exhibits the problem quite clearly. So unless my lens can pick up things behind it, I cant see this being caused by a finger. Regards Mike Link to post Share on other sites More sharing options...
earleygallery Posted December 10, 2011 Share #20 Posted December 10, 2011 It could indeed be flare - there is bright sunlight falling on the scene almost in front of the camera from the left. That's why I immediately thought a light leak via the viewfinder area. I think you need to load a new film and try to replicate the effect. Try shining a torch into the viewfinder from all angles on a blank frame of film, and shooting semi into the sun, if you're lucky enough to see it anytime soon!!
