[darktable-user] Lens distortion: Fujifilm 35mm f/2
In the video listed below I show that distortion in images produced with the Fujifilm XF 35mm f/2 R WR lens is prety sizable. It seems that Lightroom and Darktable deal with such distortion quite differently. Any thoughts on that?

darktable uses lensfun for all the lens corrections.

[darktable-user] issue with detecting canon EF16-35mm f/4L IS USM
Hello, I just relaized that I have an issue with DT detecting the above mentioned Canon lens. Photos taken until December 2014 show the correct exif and the proper lens in the correction modul. Starting in Jan 2015 (sorry, I do not use that lens very often and do not pay attention a lot to the exif and lens correction), the lens name in the exif is "(507)". Whats wrong here? The only odd thing I found is that with the old pictures the lens name is not left aligned to all the other exif fields. It looks like a preceding white space: Hersteller: Canon Objectiv:Canon EF 16-35mm f/4L IS USM Blende: F/4.0 Thats all. When I compare the exif data of 2 RAw files with exiv2 on the commandline I do not see a difference between old and new RAW files. Both show: Exif.CanonCs.LensTypeShort 1 (507) Exif.CanonCs.LensShort 3 16.0 - 35.0 mm Exif.Canon.LensModel Ascii 74 EF16-35mm f/4L IS USM Exif.Photo.LensSpecification Rational4 16/1 35/1 0/1 0/1 Exif.Photo.LensModel Ascii 22 EF16-35mm f/4L IS USM Exif.Photo.LensSerialNumber Ascii 11 225331 Any help is appreciated.

[darktable-user] Warning: git master now uses rawspeed as submodule !
Hi everyone. Starting with today, darktable git master tracks rawspeed library as a submodule. Which means, after updating darktable repo (git pull/git fetch), and before building, you now need to make sure that the submodule is updated to. After fresh clone, you need to run this once: $ git submodule update --init And day-to-day, after git pull for darktable (i'm not 100% sure about the exact command, someone with more knowledge please do chime in) $ cd src/external/rawspeed && git pull && \ git checkout -f && git submodule update -f Roman. darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org

Re: [darktable-user] 2.2.x for Fedora?
2.2.0 is already available as a update for Fedora 25. 2.2.1 is only 5 hours old as I write this, but the person that manages the Fedora packages updates them fairly quickly so it shouldn't take long.

[darktable-user] Re: issue with detecting canon EF16-35mm f/4L IS USM
I am pretty sure that this is related to my self compiled binaries in conjunction with exvi2 0.24 which does not include the Canon 16-35 mm f/4L. I can not easily install exiv2 0.25 with apt from testing ... too many dependencies. So I compiled exiv2 0.25 on my own. That was pretty easy. But now I have the issue that I need to tell DT during compile time to use the new header files and libs. I installed exiv2 in /home/software/exiv2 with subdirectories for lib and include. What do I need to add to the build script now? I tried export C_INCLUDE_PATH=/home/software/exiv2/include export LD_LIBRARY_PATH=/home/software/exiv2/lib But that did not do the trick.

Please write down your thoughts because citing a video does not work. :-) You are right, Lightroom applies lens corrections automatically for µ4/3 and Fujifilm lenses. In Darktable, you have to switch it on explicitly. That is not a big difference in my opinion, though. A much bigger difference is that at least for µ4/3, you can't even switch that off in Lightroom I think. But I don't see any point in doing that anyway. µ4/3 and Fujifilm X both store the lens correction parameters in the lens, which is then embedded into the RAW. So, no extra profiles are needed. Hopefully DT will be able to extract that info as well and pass it to Lensfun. But we are far away from that because there is not even a description how the parameters are stored and which formulae to apply. At the same time, lens correction is part of the mount specification, and lenses are designed to be corrected afterwards. And yes, this *is* a trend for lens builders: They build lenses to be digitally corrected. Seasoned photographers may not like that but there we go. My personal opinion is that every lens design is a tradeoff, and in the digital era, there should be other priorities (like weight, size, price) than the unnecessity to correct.

[darktable-user] Things are dark.....
After processing my pictures the images are dark. at least they were. You fixed that but now the 'profile' which used to give different image brigtnesses and other such things now produces all the same image. -- :-)~MIKE~(-: darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org
