TK! Posted August 9, 2015 Share #1 Posted August 9, 2015 Advertisement (gone after registration) Hi all, due to the unsatisfying colour of my JPEGS I shot raw yesterday for the first time in my life. (My memory card filled up quite fast. If I continue with raw my hard disk will do too. Wonder how to deal with that...) I am a full Linux user. No Microsoft, no Applestuff. DNG is a open standard. And many open source tools know to deal with it. This is the good part. In the first step this is true. But at a second glance I do not see a chance to get "the right colors" from the raws. Moreover how do I apply the lens correction to my raw pics? Open source tools are available for both tasks. But where do I get the colour and lens correction files from? Best whishes and thank you for the great help I already got from this forum TK P.S.: I saw the raw files without lens correction in my gimp. I will further investigate on this but sometimes the uncorrected pictures seemed much more natural than the corrected ones. Link to post Share on other sites More sharing options...

TK! Posted August 11, 2015 Author Share #3 Posted August 11, 2015 Using Linux for PP, that is brave. So which software do you use? Hi, please forgive if it's not Q-specific enough... I mainly use "www.digikam.org" which I think is a great tool for managing my pictures. It still scales perfectly with my 180.000+ files. My PP-Workflow is quite straight forward: copy pictures into digikam, there geolocate all picture based on bookmarks and gps-tracks from my external gps-logger (this became slow over the time with growing number of pictures), then quickly pass through all pics by keyboard strokes, add a star to each pic that I want to keep. If I am unsure I go to digikams 1:1-view (always a great pleasure with pics from the Q) And finished. Not deleting any pictures speeds up this process as I do not need to think too deeply about each pic because nothing is lost. And I think speed is important here, otherwise you never get through. Or even worse you never even start. Also I do crops and basic color correction with digikam from my JPGs before print. (Digikam keeps the original files, so working around with the JPGs is okay.). For really editing pics (removing cigarette stubs from wedding pictures etc.) I use www.gimp.org. This tool is very mighty but of course the bravery you mentioned is needed here. Both tools allow to directly import and work with DNG-files. But as mentioned both know nothing about the Leica Q i.e. both need the appropriate parameters for colours and lens correction for doing their job. This is where I am still stuck right now...

TimJM Posted August 12, 2015 Share #4 Posted August 12, 2015 Linux (Mint) is my preferred OS, but I have not found native Linux tools that work well for me. Now I run Windows 7 in VirtualBox and use Lightroom, Gimp and SNS-HDR as my cataloguing and processing tools. Windows is not used for web browsing or email, and is only rarely connected to the internet. No useful data are kept on the Windows virtual drive: my images, Lightroom catalogue and presets are kept on a shared Linux drive. There is a simple workaround to force Lightroom to store its catalogue on what appears to it as a network drive. Having Windows running in a window or full screen on a Linux session is far more convenient than having a dual boot system, as I can switch easily from one system to the other and back again. tjm Link to post Share on other sites More sharing options...
aalkaabi Posted August 12, 2015 Share #5 Posted August 12, 2015 Good to know TK and my best wishes. I can't do without my Mac it's a workhorse, never hang never quite, it just works. I'm not brand loyal kind of guy, I use what I feel works best. However, I respect your choice with Linux, I think you are one of very few photographers that use Linux. Good luck. I hope leica and other companies start supporting it soon. Link to post Share on other sites More sharing options...
TK! Posted August 20, 2015 Author Share #6 Posted August 20, 2015 Using Linux for PP, that is brave. So which software do you use? In the mean time I became quite frustrated. Without the colour and lens profiles all the open source software does makes sense. Lens correction might be feasible to calibrate but not colours on my low end display. So I installed Adobe's Camera Raw under Linux (straight forward with Wine!) in the hope to convert the DNGs to colour and lens corrected Tiffs for further processing. But I only get stand alone ACR to output DNGs that contain a processed Jpeg-Preview but the DNG-part does not improve. Seeing the "right" colours in the Jpeg-preview now really gave me a bad feeling concerning the out-of-the-camera-jpegs. The latter are really bad concerning the colours! Finally I gave up and registered at Adobe and downloaded Lightroom that comes with the Q. But what a disappointment, it's not a stand alone version but some cloud stuff. This will never ever run under Linux... Frustrated - TK Link to post Share on other sites More sharing options...

This will never ever run under Linux... Frustrated - TK Sorry about this late reply / comment. In case you haven't yet decided on a solution, here's my comments. Your Q was supplied with a TAN number that allows you to download (from your Leica product registration page on the Internet, ), a full version of the latest Lightroom and to licence it at no cost. That version is standalone and definitely not the cloud version. If if you proceed, is it going to be possible for you to install and run it within your preferred operating system environment. I feel that in following your principles of no windows or Apple you have made life very difficult for yourself. If you install a standalone version of LR, you will be able to run it offline to meet your safety concerns. I can can also recommend having an external hard drive for your many original image files. I use a LaCie drive and I process my RAW files in LR directly from the LaCie. Then I store my best finished files on my MacBook and iPad. Hope le that helps.

CharlesL Posted October 13, 2015 Share #8 Posted October 13, 2015 Raw Therapee is available in Linux builds. See http://rawtherapee.com/downloadsIt has a straightforward tool for correcting distortion, one of the main jobs that the Q lens requires, and a partially satisfactory tool for correcting vignetting.RT has many tools for modifying colors by hand: the R,G, and B curves, HSV equalizer, channel mixer, Lab color space curves, etc. Later, you may explore the building of a camera profile yourself for the Q, too, that RT can use.

xme53 Posted November 6, 2015 Share #9 Posted November 6, 2015 Hi, good to see other people like linux too , i am rather satisfied with the possibilities of PP in Linux. I manage my catalog in Shotwell, do my rating and tagging there and can go with a right click to Darktable which allows for color profiling and is a very powerful tool for raw development. Once brought the raw to one or two versions which give me the best for shadows and highlights i combine the layers in gimp with some alpha masks and filtering to the image i am looking for. Gimp as well allows for color profiling and i don't miss the 6bit i loose on my way. So this might not be the straightest way to get things done but it works for me. Pixls.us is a nice site where you might find more possible workflows and software that might get you where you wanna be. Of course your mileage may vary.
