freitz Posted October 2, 2015 Share #1 Posted October 2, 2015 Advertisement (gone after registration) I was not sure where to ask an a few quick searches didn't pull much up. The attached image shows a white line that is appearing in some of my pictures. Mostly sky backgrounds, F stop or ISO level does not seem to matter. Only prevalent with editing, very visible with any HDR software. Anyone know what that could be? L1000743_HDR-2 by Fred Reitz, on Flickr Link to post Share on other sites More sharing options...

Peter Kilmister Posted October 2, 2015 Share #2 Posted October 2, 2015 Have you cleaned the sensor? Link to post Share on other sites More sharing options...
freitz Posted October 2, 2015 Author Share #3 Posted October 2, 2015 Have you cleaned the sensor? I had the Sensor Cleaned by Leica in April. I have not cleaned since then but under inspection I don't see anything on the sensor. 1-2 tiny dust spots that Im not worried about and not visible until F16.

pop Posted October 2, 2015 Share #4 Posted October 2, 2015 I can not see any white lines. Where are they supposed to be and do they run in a particular direction? Link to post Share on other sites More sharing options...
freitz Posted October 2, 2015 Author Share #5 Posted October 2, 2015 I can not see any white lines. Where are they supposed to be and do they run in a particular direction? Its not stand out ish white. Something similar to what it looks like when the sensor needs remapping. But I don't think that is it. Ill add another picture showcasing the line more easily Link to post Share on other sites More sharing options...
freitz Posted October 2, 2015 Author Share #6 Posted October 2, 2015 L1003424_HDR-Edit by Fred Reitz, on Flickr This is an way over edit with HDR software but can you see the line better in this photo? Link to post Share on other sites More sharing options...
Peter Kilmister Posted October 2, 2015 Share #7 Posted October 2, 2015 Advertisement (gone after registration) Yes, you have a white line. I could see that in the original shot. Very annoying too! If you have tried cleaning the sensor then I don't know what to suggest. It's probably best to await the services of someone far more knowledgeable than me. Meanwhile it can't hurt to use an manual air blaster to clean the sensor again in line with all the recommended methods. Link to post Share on other sites More sharing options...

Schrödinger's cat Posted October 3, 2015 Share #9 Posted October 3, 2015 WAG. While I've never seen it displayed in exactly this manner, it suggests to me a pile readout issue. I rather suspect that this is a service issue and not something that will respond to user intervention. Link to post Share on other sites More sharing options...

thighslapper Posted October 3, 2015 Share #11 Posted October 3, 2015 This was present is some images on the M8/9 and was exactly midline ...... due to the fact that the CCD sensor was read out in 2 halves and subsequent corrections carried out to the data shows up as a faint mismatch between the two halves in certain conditions and ISO's. Not sure if this is the same for CMOS sensors...... I doubt it because the architecture is different ....... but it does look suspiciously central to me. Otherwise, no a clue.

luigi bertolotti Posted October 3, 2015 Share #12 Posted October 3, 2015 It looks not straight... not a problem located on some pixels strings, I'd say...and if you say it becomes more visible on skies, I tend to think is a problem related to the sensor's assembly... something in a certain area of glass/bayer filter/UV filter package... an issue to be solved at factory, definitely.

edwardkaraa Posted October 3, 2015 Share #14 Posted October 3, 2015 I'm just guessing but this looks like a cleaning mark. Perhaps a wet cleaning would be advisable before sending it to service. By the way, never let Leica clean your sensor, as their cleaning methods are actually ineffective and dangerous. Sensor swabs with eclipse remains the best safest most effective way.

freitz Posted October 3, 2015 Author Share #15 Posted October 3, 2015 Just checked older photos. Not cleaning marks, also checked sensor. The line is suspiciously straight when I look at other photos. It definitely split right down the middle. Crazy thing is once you notice it you find it in s lot more pictures.

Peter Kilmister Posted October 3, 2015 Share #16 Posted October 3, 2015 Please describe exactly what camera type you are using and how long you have had it. My reason for asking is not nosiness, it is so that the experts might have a better chance of analysing the problem. Link to post Share on other sites More sharing options...
