Shane Dalyq Posted November 14, 2010 Share #1 Posted November 14, 2010 Advertisement (gone after registration) Hi all My first post here, I recently purchased my first Leica and after initial disappointment have quickly grown to love it dearly. I sold my f2 28mm for a f1.5 50mm Zeiss and an f1.4 Voigt 35mm which are both smashing. I have noticed that one some shots a pronounced horizontal striation manifesting above 800ASA on the M9 - are this sensor artifacts? They appear particularly evident when graded for B&W. Please advise! Thanks very much Shane Shane Daly ========= Cinematographer Shane Daly: Home UK +44 7973 445 428 US +1 310 746 6516 skype shanejustindaly Link to post Share on other sites More sharing options...
Advertisement Posted November 14, 2010 Posted November 14, 2010 Hi Shane Dalyq, Take a look here M9 Horizontal lines / striation. I'm sure you'll find what you were looking for!
viramati Posted November 14, 2010 Share #2 Posted November 14, 2010 I find this can happen at higher iso if image is underexposed. I you can keep the histogram to the right it should help to avoid this issue Link to post Share on other sites More sharing options...
jaapv Posted November 14, 2010 Share #3 Posted November 14, 2010 If you push the exposure hard enough-that is way beyond reasonable limits-, the M9 will produce a Tartan-like pattern. Link to post Share on other sites More sharing options...
Dan States Posted November 14, 2010 Share #4 Posted November 14, 2010 Jpeg or raw? It typical on jpegs. Link to post Share on other sites More sharing options...
zlatkob Posted November 14, 2010 Share #5 Posted November 14, 2010 I haven't noticed any such lines. Perhaps post a straight-out-of-camera example (no post-processing). Link to post Share on other sites More sharing options...
Shane Dalyq Posted November 14, 2010 Author Share #6 Posted November 14, 2010 Thanks for the replies guys. It was a RAW compressed, about 1 stop under. Really showed up when grading quite hard, will endeavour to be more careful with exposures in future Link to post Share on other sites More sharing options...
adan Posted November 15, 2010 Share #7 Posted November 15, 2010 Advertisement (gone after registration) "Grading"? Haven't heard that expression in this context. Does that derive from video post-production terminology, like "color timing" and such? I "graded" images when I was a teaching assistant in grad school - "This images gets an 'A'. That image gets an 'F'. " etc. Link to post Share on other sites More sharing options...
Shane Dalyq Posted August 15, 2011 Author Share #8 Posted August 15, 2011 Yes, grading is colour correction / timing, it's a film industry shorthand. Link to post Share on other sites More sharing options...
brill64 Posted August 17, 2011 Share #9 Posted August 17, 2011 i've recently experienced horizontal banding appearing quite frequently in the shadow areas of well exposed raw and in-camera jpg's and also files converted to jpg from dng. i habitually underexpose -2/3 stop but these files are mostly shot at iso160!! I'm not overly processing them either. the strange thing is that the banding appears intermittently, ie., the dng and jpg files either side can be completely fine. the oddest thing i noticed was that if i used the camera in portrait format, the banding would still appear left to right as in landscape format and not top to bottom as you'd imagine.

jaapv Posted August 17, 2011 Share #12 Posted August 17, 2011 Send these samples to Leica. I'm sure the camera has a problem with the motherboard and needs a motherboard/sensor replacement. Link to post Share on other sites More sharing options...

jaapv Posted August 23, 2011 Share #15 Posted August 23, 2011 If/when you send the camera in ( I would advise Fedex, despite the price), do send the SD card (with the images) with it. Link to post Share on other sites More sharing options...
ErickPRO Posted December 12, 2014 Share #16 Posted December 12, 2014 I'm experiencing something similar on my M9. Already sent the camera for repair today. I will let you know what happens.

Malvolio Posted December 13, 2014 Share #17 Posted December 13, 2014 I had this issue - it is card related and also shooting continuously provokes it. Link to post Share on other sites More sharing options...
Malvolio Posted December 13, 2014 Share #18 Posted December 13, 2014 I found also if you shoot before the red light stops blinking it can provoke it , especially in underexposed areas. I now own an M240 Link to post Share on other sites More sharing options...

exile Posted December 13, 2014 Share #20 Posted December 13, 2014 The thick horizontal green band you show on the second image is exactly what I experienced on my M9. It showed at every ISO but was far less pronounced at ISO180. Always at the same location in the frame, generally origination from a very high contrast transition and extending to the left hand side of the frame. I sent the camera to Leica and it has resided there since the start of October awaiting a replacement sensor. Link to post Share on other sites More sharing options...
