rivi1969 Posted April 25, 2015 Share #1 Posted April 25, 2015 Advertisement (gone after registration) Good evening friends, Well, another case of the sad vertical line issue here. So I would like to know -considering the sensor is no longer replaceable- if there is somebody else like me who has to live with this situation in all of its pics. The truth is I am a patient man and I could spend a couple of minutes with each raw file removing it manually in Lightroom, But my main concern is how bad it could get with time... Does it will develop more vertical lines until the whole sensor is infected? (I can see them at all ISO settings) So far I see one long in the left portion of the image and one tiny coming from bottom to top on the right. I can live with it as it is, but I wonder once the sensor dies, should I simply trash it? I don´t think Leica will take it as down payment for a sweet M-E anymore. Kind regards, Ricardo 1 Quote Link to post Share on other sites More sharing options...

Lenshacker Posted April 25, 2015 Share #2 Posted April 25, 2015 (edited) Leica should be able to map out the Bad Pixel and stop the line from happening. You can also use Arvid's M8RAW2DNG and map out the bad pixel. Also get the benefit of Uncompressed DNG, which is very much worth it. http://m8raw2dng.de/ You can also try this software, http://people.csail.mit.edu/ericchan/tmp/FixBadPixels.pdf Which puts the instructions in the DNG file to correct the bad lines.

rivi1969 Posted April 25, 2015 Author Share #3 Posted April 25, 2015 Thank you Lenshacker, I will try the second option, when I download http://m8raw2dng.de/ on my Mac it only opens a text message who says: # m8raw2dng v1.10 # ################### Program converts Leica M8 RAW+JPEG pairs to DNG. Usage: m8raw2dng.exe -switch1 value1 -switch2 value2 ... Supported switches (values) [default value]: -i input: (folder or file) [location of m8raw2dng.exe] -o output: (folder) [input folder] -v verbose -r refresh: existing DNG files will be overwritten -b blacklevel estimation -p preview image 320x240 in DNG -c embed M9 color matrix -l load lens exif from lensdb.ini Help, feature suggestions & bug reports => m8raw2dng.de © 2013 Arvid Kuehl logout [Proceso completado] I will try the second process to see if I get lucky. Thank again! R Quote Link to post Share on other sites More sharing options...
pop Posted April 25, 2015 Share #4 Posted April 25, 2015 -considering the sensor is no longer replaceable- Who told you that the sensor is not replaceable? We all know that the display can not be replaced; to the best of my knowledge, Leica still carries and replaces all other parts of the M8. 1 Quote Link to post Share on other sites More sharing options...
david strachan Posted April 25, 2015 Share #5 Posted April 25, 2015 Oh Ricardo...not your new M8 gone bad already... This problem can be fixed using Photoshop: max zoom, select one column (or row), copy, move over line of dead pixels, paste. This covers up the line with a new set of pixels from "next door".

williamgm Posted April 25, 2015 Share #6 Posted April 25, 2015 Who told you that the sensor is not replaceable? We all know that the display can not be replaced; to the best of my knowledge, Leica still carries and replaces all other parts of the M8. Indeed, while considering a Leica M8.2 early in March this year I contacted Leica customer services and, with the exception of the rear display/lcd, they confirmed that all parts were still available for repairs. You should therefore be able to have the sensor replaced if you wanted to. Geoff 1 Quote Link to post Share on other sites More sharing options...

Somewhere in the vast world wide web I read they don't have any more sensors for the M8. But it is good to know they do I think I will learn to live with it as-is and fix the files manually, anyway I only shoot RAW and I don´t mind spending a couple more minutes doing the job. Thanks!

All best Dave S I know my friend! I felt disappointed but mostly worried because I thought the sensor was gonna die and be irreplaceable, but now I read Leica can remapped it (or even change it) so the fear is gone and I think I don´t want to send it away now that I just got it, I will "embrace it" and do the PS trick ) Thank you.

All best Dave S Use 100%. Beyond that PS will manufacture pixels to make the line wider. Find the start point, hold down shift key to keep perpendicular to edge, select the line. On the top, make the selection 1 pixel wide. There are options to make the line take on nearest neighbor. Try smart fill. The start point will have x,y, coordinates. Write an action to preform this function and the computer can run through a whole folder of files in short order, say 2 sec per image. Leica really needs a fix for this. Nikon.Canon do not have it. 1 Quote Link to post Share on other sites More sharing options...
rivi1969 Posted April 30, 2015 Author Share #13 Posted April 30, 2015 (edited) Thanks for the advice... The problem is the vertical line is wider than 1PX... it is 1 pixel causing the problem, but the affected lines are 3 pixels wide, one on each side. So I guess the best option is simply sending the camera to NJ and wait a couple of months to get it fixed. Doing the Photoshop work is ok with a few pics, but going through hundreds will make me wish I took them with my always reliable 5D instead.

Lenshacker Posted April 30, 2015 Share #14 Posted April 30, 2015 The one pixel should be leaving 1 column dead, but the demosaic routine will cause it to affect those next to it. If the software can fix it in the DNG file, the spillage should not be as bad. Did you have any luck with the "Bad Pixel Fixer"? Quote Link to post Share on other sites More sharing options...

Have you contacted the repair department at Leica, USA in New Jersey? You may be surprised at the time to remap the sensor. Quote Link to post Share on other sites More sharing options...
rivi1969 Posted April 30, 2015 Author Share #16 Posted April 30, 2015 No luck with the Fix Bad Pixel... I did all steps including creating a diagnostic TIFF to get the pixel coordinates, but once I drop the original M8 DNG file into the FIXBADPIXEL app, it shows this: ***Error: File format is invalid *** (1) so I don´t know what´s going on here, because when I use the .dng file that comes as example with the app it works just fine. My files are .DNG (?) I am just one step away from success. Quote Link to post Share on other sites More sharing options...
Lenshacker Posted April 30, 2015 Share #17 Posted April 30, 2015 That is frustrating! You might want to contact the person that wrote the software, probably would be interested to know about the problem. The M8 DNG files straight from the camera use a compression scheme with a "look-up-table" to get the values restored. I'll bet the software cannot figure it out. Very frustrating! It would be best to have Leica map the bad pixel out, too bad the "quick fix" isn't quick and does not fix! Quote Link to post Share on other sites More sharing options...
david strachan Posted May 1, 2015 Share #18 Posted May 1, 2015 (edited) Your camera is old. It needs a service anyway. Leica may be good enough to replace the sensor, free. They are very good like that; it keeps a lot of Leica loyals confident they back their products for life. It'll come back with new covering, full clean, rangefinder calibration, full service and a one year warranty; and a brand new sensor. You'll miss it for only a short time then will have a "new" camera. cheers Dave S Edited May 1, 2015 by david strachan Quote Link to post Share on other sites More sharing options...
rivi1969 Posted May 1, 2015 Author Share #19 Posted May 1, 2015 Lenshacker & Dave, Yes... The best bet is simply ship the camera to NJ and have it remapped -I doubt it will be free- since it will be gone for a few weeks I will order a nice CLA, and even change the leatherette skin for the vulcanite or the one on the new M-E. I hope the sensor work won't be too expensive, I am thinking something in the 300dlls range. Cheers! Quote Link to post Share on other sites More sharing options...
jaapv Posted May 1, 2015 Share #20 Posted May 1, 2015 I've never heard of anybody being charged for sensor remapping, but there could always be a first... After all, it is just running a remapping program over the firmware. If the number of affected pixels exceeds the maximum the sensor will be replaced. In that case you won't have to specify a CLA and leatherette, as it will be done automatically. 1 Quote Link to post Share on other sites More sharing options...
