<p>I thank all for the helpful feedback.</p> <p>I did as 'Bill C' suggested:</p> <blockquote> <p>There are a lot of good ideas here, but I think an effective way to troubleshoot would be to run a roll halfway through the camera (taking photos) then rewind. If you find scratches halfway through the roll and then they stop, you know they are from either the camera or cassette. Additionally, you'd be able to find the exact spot in the camera based on the last frame exposed.</p> </blockquote> <p>Hereafter, I could conclude that the problem was in the camera, as I didn't have any scratches on the unexposed part of the negativ.<br> The camera has therefore been sent to service at Leica in Germany, again.<br> Once again, thanks for all the responses. </p>

<p>#1 <br />Mr. Angel, I doubt that the problem is coming from the Leica, as I always keep it nice and clean. And even just got it back from service. <br> As I use a wetting agent, hereafter, I just let the negatives hang dry; the problem can't be from a squeegee tool.<br /><br />Particles on water, I don't belief that the water can leave these lines, however I also use desterilized water for the final wash.<br /><br> If you look at some of the (now) attached photos, you might notice that two parallel straight lines occur sometimes. And the only thing I can think of, is the wheel inside of the scanner. <br />However then I read this: http://www.photo.net/digital-darkroom-forum/00DQLx<br> <br />#2 Mr. Lewis, I only use fresh cartridges.<br /><br />#3 Mr. Monday, I'm of the same idea regarding the 'test', and I try it out. However, do you think the nikon coolscan 4000ed is able to make those scratches, see below: <br /><br /><img src="http://d6d2h4gfvy8t8.cloudfront.net/18120662-md.jpg" alt="" width="680" height="446" /><img src="http://d6d2h4gfvy8t8.cloudfront.net/18120661-md.jpg" alt="" width="680" height="445" /><img src="http://d6d2h4gfvy8t8.cloudfront.net/18120660-md.jpg" alt="" width="680" height="446" /><img src="http://d6d2h4gfvy8t8.cloudfront.net/18120665-md.jpg" alt="" width="680" height="445" /><img src="http://d6d2h4gfvy8t8.cloudfront.net/18120664-md.jpg" alt="" width="680" height="447" /><img src="http://d6d2h4gfvy8t8.cloudfront.net/18120663-md.jpg" alt="" width="680" height="444" /></p> <p> </p>

<p><img src="file:///Users/DenizGyl/Desktop/scanPB/scan0012.jpg" alt="" />Hello,<br /> Lately, I have had a problem with my negatives being scratched with long straight lines.<br />I have tried to isolated every single process to find out, where in the process this happens, without luck.<br /> The scratches occurs at different places, however, mostly on the mid - or lower mid of the image.<br />It occurs randomly on the negatives. In other words, some on the first part of the roll, and some could occur on the last part.<br /> It would be really helpful if anyone have an idea about, where they could come from.<br />My workflow underneath, step for step, for a deeper insight in where it could have gone wrong.<br /> My workflow:<br />Shooting on a Leica m6 with a 50mm summicron<br />I only shoot on Kodak Tri-X (non-expired).<br /><br />Develop with Kodak D-76 in a Paterson tank, which carries 3 wheels.<br />Stop with vinegar<br />Fix with Ilford Rapid fixer<br />Final wash is with desalinized water and adox adoflo - wetting agent<br />I hang dry the negatives in the bathroom<br /> I cut them and archive them in folders<br />I scan them on a Nikon Coolscan 4000ed using the sa-21 head. <br /><br /><br /> Attached some examples... how do I even do that?<br /> thanks,<br />Deniz</p>
