bideford Posted December 26, 2013 Share #1 Posted December 26, 2013 Advertisement (gone after registration) Seasons greetings to everyone. Quick question - for sensor remapping due to a dead pixel - will the camera have to go to Solms or can it be done at Mayfair (I'm UK based)? I'm guessing Solms but thought it worth asking.

Advertisement Posted December 26, 2013 Posted December 26, 2013 Hi bideford, Take a look here Sensor remapping (dead pixel) - where?. I'm sure you'll find what you were looking for!
pico Posted December 26, 2013 Share #2 Posted December 26, 2013 One dead or stuck pixel is not worth the worry. If you have, for example Photoshop, you can make an action that quickly automatically fixes it - or very many files all at once. Link to post Share on other sites More sharing options...

Leonil Posted December 28, 2013 Share #4 Posted December 28, 2013 Or you can ask for a replacement, since you know - you spent 5000+ pounds on it and you expect good Quality Control at Leica. One Dead pixel isn't good enough imo. Link to post Share on other sites More sharing options...
John Black Posted December 28, 2013 Share #5 Posted December 28, 2013 All sensors have mapped out pixels. If the offending pixel is at ISO 200, then I would get it mapped out. If the offending pixel(s) only show hot at upper ISOs, then it is not worth having it mapped out (unless it's causing a column read out error where all or part of the column is just a blank line).

StephenPatterson Posted December 28, 2013 Share #6 Posted December 28, 2013 I know I will catch some flak for this but mapping out dead pixels, clusters, rows and columns should not require the camera be shipped off. I'm not suggesting a major rewrite of the code to include this in-camera, but certainly a program could be provided to distributors, or better yet dealers, or better still customers, allowing re-mapping via USB connection.

jippiejee Posted December 28, 2013 Share #7 Posted December 28, 2013 Advertisement (gone after registration) I wouldn't bother for single pixels, they're a fact of sensor life. Lightroom already automagically removes dead pixels in the develop mode. Link to post Share on other sites More sharing options...
pico Posted December 28, 2013 Share #8 Posted December 28, 2013 I'm not suggesting a major rewrite of the code to include this in-camera, I am. Olympus provides in-camera remapping. . Link to post Share on other sites More sharing options...
BerndReini Posted December 28, 2013 Share #9 Posted December 28, 2013 Considering the money they are charging for their products, Leica really need to hire some smart people to figure out some technical issues. I own an old Phase One back and, while I can't do pixel mapping myself, Phase One offers a service where you upload a few sample pictures and they write a correction in the form a firmware update specific to the digital back to get rid of offending pixels. Not free, but convenient. Link to post Share on other sites More sharing options...
Berlinman Posted December 30, 2013 Share #10 Posted December 30, 2013 Has someone a good simple way to repair pictutes with dead colomns ? I work with Aperture and LR5. Sent from my iPad using Tapatalk - now Free Link to post Share on other sites More sharing options...
Dougg Posted December 31, 2013 Share #11 Posted December 31, 2013 Has someone a good simple way to repair pictutes with dead colomns ? I work with Aperture and LR5. Well, there is Eric Chan's "FixBadPixels" which you can find here: Eric Chan (scroll down near the end to see the link to download the zip file). Back before this was around, I fixed my full-scale TIFF file that was output from the raw converter. Open the TIFF at 100% in a graphics editing program, find the bad column, select everything to the right of this column and bump it leftward one pixel. Save, done.

Berlinman Posted January 1, 2014 Share #12 Posted January 1, 2014 Dougg: thank You for the good idea. Sonds like this is what I need. I tried it, but it doesn't work on my system 10.9.1. I wrote a message to Eric. Hope he can help. Sent from my iPad using Tapatalk - now Free Link to post Share on other sites More sharing options...

bocaburger Posted January 6, 2014 Share #15 Posted January 6, 2014 Epson released an updated firmware with a pixel remapping utility for the R-D1. I would like to hear the technical explanation from Leica themselves as to why they can't or won't do so for the M (and ME, MM and M9/M9P). And yes I know LR will cancel out hot pixels, but sometimes I just want to shoot jpegs for someone else and burn them to a disc. Link to post Share on other sites More sharing options...
wlaidlaw Posted January 6, 2014 Share #16 Posted January 6, 2014 I suppose it would depend on what level of access the USB port on the M8/9 grants. Leica may have to plug a cable into the main PCB to re-map. Wilson Link to post Share on other sites More sharing options...

Leica may have to plug a cable into the main PCB to re-map. Wilson The Epson R-D1 firmware update didn't involve tethering, there was a mapping utility on the in-camera menu. I suppose in the case of the Leicas it would be a matter of whether there is enough room in the firmware for a mapping utility but it would seem odd if the Epson had enough space and the Leicas don't.

I suppose in the case of the Leicas it would be a matter of whether there is enough room in the firmware for a mapping utility but it would seem odd if the Epson had enough space and the Leicas don't. The Epson doesn’t do in camera lens correction, which may occupy a lot of FW code space. Also Epson had a lot more experience in electronics than Leica had, so there may be more custom chips in the RD-1. The M8 uses pretty much all off-the-shelf components in its electronic suite.

jaapv Posted January 7, 2014 Share #19 Posted January 7, 2014 Also the RD 1 had a slightly less pixels and somewhat smaller files, so it would need less processing power. Link to post Share on other sites More sharing options...
