andybarton Posted February 15, 2009 Share #1 Posted February 15, 2009 Advertisement (gone after registration) In the sky on this shot, you can see some vertical streaks. I can't work out what they might be. I thought that they might be a light leak, but this streaking hasn't shown on any of the other films I have taken recently. This is taken with the M2, a camera which was CLA'd by Leica about 2 years ago. If the streaks were running across the frame, I could put it down to development technique, but this has got me confused this afternoon, I have to say. Any ideas?

thetooth Posted February 15, 2009 Share #2 Posted February 15, 2009 do you pre wet the film before start development . i soak my film for 2 to 3 minutes before i start the process . Link to post Share on other sites More sharing options...
andybarton Posted February 15, 2009 Author Share #3 Posted February 15, 2009 No I tried that once years ago and was not happy with the result I got. Maybe I should try again. Link to post Share on other sites More sharing options...
MPerson Posted February 15, 2009 Share #4 Posted February 15, 2009 Andy - 1. was this via the Nikon scanner? 2. was this roll the first you scanned? 3. are the streaks visible on all the frames? I had something similar but not so pronounced and I resolved it by letting the scanner warm up for 10 mins. Link to post Share on other sites More sharing options...
thetooth Posted February 15, 2009 Share #5 Posted February 15, 2009 yes i find it produces a more even development . like i said i let the film soak for a good 2 minutes before i start the process , just make sure the temperature does not vary form the developer temperature much . also when you pour out the pre soak the water may be black or purple this is normal and will not affect development .

Shootist Posted February 15, 2009 Share #6 Posted February 15, 2009 There was a thread recently about bad/old/weak Fixer causing streaks. If this was the top roll of the 2 then it could be you didn't fill the tank enough with fixer or you didn't agitate good enogh during the fixing process.

andybarton Posted February 15, 2009 Author Share #7 Posted February 15, 2009 Advertisement (gone after registration) That could be it. The fixer was the end of one bottle and the beginning of a new one. I don't know whether this was the top or bottom of the tank, but that could explain it. Cheers for the help guys. Andy - 1. was this via the Nikon scanner? 2. was this roll the first you scanned? 3. are the streaks visible on all the frames? I had something similar but not so pronounced and I resolved it by letting the scanner warm up for 10 mins. Yes this was the Nikon. It was not on the first roll, and the scanner had been on for quite some time. The streaks are visible on the negatives. Link to post Share on other sites More sharing options...
gravastar Posted February 15, 2009 Share #8 Posted February 15, 2009 If the streaks have been caused by insufficient or exhausted fixer then you should be able to remove them by re fixing the film in fresh fixer. Before re fixing I'd suggest soaking the film in water to which a few drops of wetting agent have been added. Then fix, wash and dry as normal. In the meantime keep the negatives out of very bright light since any remaining silver halide would be somewhat light sensitive. I'm assuming the shot is a vertical one and that the streaks don't correspond to sprocket hole positions. Bob. Link to post Share on other sites More sharing options...
earleygallery Posted February 15, 2009 Share #9 Posted February 15, 2009 Odd one, different to the 'sprocket hole' phenomenom. I'd try re-fixing anyway, it's not going to harm the film to do so and it will at least eliminate one possible cause! Link to post Share on other sites More sharing options...
stunsworth Posted February 15, 2009 Share #10 Posted February 15, 2009 Can you see the lines on the negative? My first thought was that it was a scanner problem, but if that was the case I'd expect the lines to be horizontal not vertical. Link to post Share on other sites More sharing options...

lincoln_m Posted February 16, 2009 Share #14 Posted February 16, 2009 Andy it is mucky rubber on the shutter blind edge which shows up on clear sky and fast shutter say 1/1000. Regards Lincoln Link to post Share on other sites More sharing options...
andybarton Posted February 16, 2009 Author Share #15 Posted February 16, 2009 Thanks Lincoln The shutter speed would have been around 1/250th for these Link to post Share on other sites More sharing options...
Don'tknowmuch Posted February 16, 2009 Share #16 Posted February 16, 2009 I thought the speed the shutters travel at remains the same regardless of shutter-speed? They just set off at different moments trailing a gap of different magnitudes. Thus, if it was some sort of shutter deposit it would happen at all speeds. Besides, the streaks do look a little off-line; not truly along the line of the neg. And they look somehow fluid in origin... All of the recent Fixer Problems have manifested themselves with streaks running across the neg, between sprocket holes, and this is clearly running along the film. not to say it isn't some sort of fixer issue, though it could equally well be a developer one. Do you stop the developer before fixing? Was the film unwashed or unstopped for a period after draining out the developer before the fixer went in? Is it possible, say, that you were tipping out the developer, with a twist to the tank, and fresher developer ran lengthwise along the film on its way out? Maybe we should entrust this one to Sherlock Holmes who, when all probable causes have been eliminated, would have to conclude that the sky was actually streaked when you took the photo?

elansprint72 Posted February 16, 2009 Share #17 Posted February 16, 2009 I've never seen fixer streaks running along the film, how could that happen? I do have some fine examples in my collection where streaks run across the film, starting from the sprocket holes. Northern Lights- IR effect?

johnbanting Posted February 16, 2009 Share #18 Posted February 16, 2009 Andy, If this is one of the first frames on the roll, it could be a slight leak through the light trap on the film cannister when loading or unloading from the camera or, depending on your processing set up, when loading into the developing tank. Or it could be a film manufacturing fault, but that's probably unlikely. Link to post Share on other sites More sharing options...
andybarton Posted February 16, 2009 Author Share #19 Posted February 16, 2009 Thanks again - I will check the frame number (I think that this is from mid-roll, but I can't be certain). The tank is loaded in a lightproof bag, so I don't think it could be that Link to post Share on other sites More sharing options...
lincoln_m Posted February 16, 2009 Share #20 Posted February 16, 2009 Andy, How about trying either a slide film or colour print film (24 exposure) as a test and getting Jessops to just develop the film ( or also make prints ) as 6x4 for 24 shots would only be about £10 maybe less, just as a test to see if it is the camera or your developing. I assume it is visible on the neg and is not a scanner issue? When I had an issue with my M6TTL shutter a few years back it only happened with 1/1000th because the shutter blind gap is only 2mm and a small bit of old rubber say 0.5mm will give a 1.5mm gap for a small part of the film ( a line along the length ). Initially I saw this on my slides and even Leica did not know what it was until they had the camera in and could see the muck on the shutter blind edge. Personally I do not know how I could have seen it without taking the camera apart. You could also run a film through your R8 and do the same developing but I suspect that will be OK. Leica only charged about £50 a few years ago to clean the shutter blind and check but it did take a few weeks to fix. I think I bought my MP soon after, but Leica did a good job in making the M6TTL better than new. Regards, Lincoln Link to post Share on other sites More sharing options...
