Hodc Posted December 19, 2009 Share #1 Posted December 19, 2009 Advertisement (gone after registration) Hello, Winter as arrived in The Netherlands so i almost fell this morning with M8. PFFFFFfffff... The camera unfortunately did fall, on the lenshood, i managed to keep upright. When viewing the pictures a noticed this line. Strangly its only on some of the pictures and mostly or always on the horse. This is a 1200 ISO-shot, forgot the ISO after inside-pictures in stable. Could this be a failure as result of the fall? C1-processing. Advice is very welcome. Harry Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

Advertisement Posted December 19, 2009 Posted December 19, 2009 Hi Hodc, Take a look here Whats this line on the horse?. I'm sure you'll find what you were looking for!
andybarton Posted December 19, 2009 Share #2 Posted December 19, 2009 Perhaps it's the horse... Try photographing a blank painted wall to see if you can see any anomalies Link to post Share on other sites More sharing options...
jsrockit Posted December 19, 2009 Share #3 Posted December 19, 2009 Looks great anyway... it is weird it is only on the horse though. Link to post Share on other sites More sharing options...
lct Posted December 19, 2009 Share #4 Posted December 19, 2009 Sounds like banding on one underexposed subject. More visible at high isos. Welcome, dear visitor!

nhabedi Posted December 19, 2009 Share #5 Posted December 19, 2009 Sounds like banding on one underexposed subject. More visible at high isos. The question is whether this part was really underexposed and if so by how much. From the posted JPG it doesn't look like it, so maybe the DNG would be helpful. Harry, did you do anything to the picture in C1 except for converting and exporting it? Link to post Share on other sites More sharing options...

Nhabedi, It is also visible on the unconverted DNG. I only did adjust whitebalance in C1. It was far off. The horse is slightly underexposed, i think. I try the black wall Andy. The horse is called Pandor. So ..... Thanks Lct and Jsrockit, Harry Link to post Share on other sites More sharing options...
rob_x2004 Posted December 19, 2009 Share #7 Posted December 19, 2009 Advertisement (gone after registration) Hunt around. You will find it pretty much all the way across. Id say the high exposed whites are masking it. Seems to have a hard edge top and fade out below over a fair area, (or above I guess on the sensor.). ..... Welcome, dear visitor!

adan Posted December 19, 2009 Share #8 Posted December 19, 2009 What is the history of the camera? This looks like the green bands that turned up in the very first batch of M8s in 2006. Did you buy it used or new...and when? What are the first digits in the serial number (310xxxx or lower?) (It also looks like the green bands caused by bright light sources on the frame edge - but since there is no obvious bright light source....) Link to post Share on other sites More sharing options...

Thanks Andy. Ok Rob, had not seen that yet. Here is another one, now i can see its all the way. Tryed on a black wall as Andy suggested, no line visible. Welcome, dear visitor!

dpattinson Posted December 19, 2009 Share #10 Posted December 19, 2009 I get similar effect on high iso shots recently with my M8 (which was serviced in Solms early this year). It's generally a full-width section of the image with a distinct edge. Visible in both the DNG and jpeg. I don't think it's necessarily an issue of underexposure as the section always includes the entire width of the frame. It is of course more visible on darker areas of the frame. I generally manage to mask it out by using a levels adjustment in the affected area. I haven't noticed it correlating to any particular light source or conditions, happens to me indoors as well as out. Link to post Share on other sites More sharing options...
Hodc Posted December 19, 2009 Author Share #11 Posted December 19, 2009 David, Thats a fine advice to mask it out. May i ask. How do you fix that, selecting the line and adjust levels how? Harry Link to post Share on other sites More sharing options...
dpattinson Posted December 19, 2009 Share #12 Posted December 19, 2009 David, Thats a fine advice to mask it out. May i ask. How do you fix that, selecting the line and adjust levels how? Harry Usually the affected area is slightly lighter than the rest of the image in my case. However the general approach should work fine for your shot too: Open in CS4 Create a new levels layer, set it to 'Luminosity' to avoid changing colours. Select the area using the rectangular marquee tool. Mask the unaffected part of the image, you will need to play around with the edge of the mask to minimize any overlap of the levels adjustment. Depending on the detail in the edge area - you may need to do some healing brush work after fixing the levels. Adjust the black and midtone levels until the affected area appears identical to the rest of the image. Do any final edge fixes with healing brush or clone stamp if required. This generally gets the image back to acceptable, or entirely removes the issue depending on your patience and what kind of detail was in the edge area. Hope this helps, do let me know if you get any sensible info on this issue from Leica. Link to post Share on other sites More sharing options...
Hodc Posted December 19, 2009 Author Share #13 Posted December 19, 2009 Ok thank you David, i will try that the next days. And will send you a PM if Leica does react. Harry Link to post Share on other sites More sharing options...
mikki Posted December 19, 2009 Share #14 Posted December 19, 2009 Yep, I've got exactly the same problem and my camera is in Solms at the moment to fix it. I hope they'll come up with a solution for this problem, but their emails didn't look very promissing. (they seemed a little suprised about it) I'll keep you informed :-) Link to post Share on other sites More sharing options...

Did you see it only at 1200 ISO? And could you post an image if its not too much trouble? I wonder if its on the same height.. Well there is our Christmas surprise. Thanks for posting.

Doc Henry Posted December 20, 2009 Share #16 Posted December 20, 2009 Harry, Sorry for this problem Try to change the card ! If another card with the same problem, i think it's a sensor problem ! Which card have you ? Sandisk Extreme III 4 gb for me ..... if other LUF friends have ideas ..... Link to post Share on other sites More sharing options...
rob_x2004 Posted December 20, 2009 Share #17 Posted December 20, 2009 On this one it really doesnt look like a line to me but the total area below, (or above on the sensor). If you cover the line your eye joins the halves, and it is less visible. You really need to be flicking the curves round real time to see the difference, but beneath the obvious line it just seems denser. Maybe adequate exposure covers it or it doesnt occur, and it is something you only experience at higher iso. Alternatively, you might want to check your file uploading and make sure it isnt a problem somewhere between card and stored file. I think hte only people that can tell you whether it is the camera will be Leica. Good luck with it. ..... Welcome, dear visitor!

Hodc Posted December 20, 2009 Author Share #18 Posted December 20, 2009 Thanks Rob and Henry, I try another card but use the same Sandisk. And i will check if there is an import-problem and try uploading again. I can see that the whole area is differently exposed. I wonder if the cold has something to do with it. Thanks guys for all your advice and suggestions. Harry Link to post Share on other sites More sharing options...
mikki Posted December 21, 2009 Share #19 Posted December 21, 2009 The line on my sensor isn't at the same height as yours, but I've got the feeling that it is placed rather randomly in the image. It occures mostly at ISO 1250 or 2500, but I think I've also seen it at ISO 640. Leica was quite suprised when they received my image and I've been told that they're still discussing it. Maybe they'll finally bring out a fix for it now. Below is an example at 2500. Apart from the color-cast, nothing has been altered (JPEG straight from the camera). Welcome, dear visitor!

mikki Posted December 21, 2009 Share #20 Posted December 21, 2009 Second example (same kitty). In the second image I increased the fill-light to make the line more visible. I browsed through my pictures, and it seems to me that the problem mainly occurs with slow shutter speeds. Maybe it a shadow from one of the shutterblades or a heat issue?? Welcome, dear visitor!
