I have a Nikon d800. I am processing NEF files using darktable 1.1.4 under Fedora Linux 17.
According to http://wilson.bronger.org/lensfun_coverage.html, both my lenses should be in the lensfun database. They are the Nikkor 24-70mm f/2.8G ED Nikkor 70-200mm f/2.8G ED-IF AF-S VR (Actually, I think I have the f/4 version of the second lens, but I am willing to try the f/2.8 data. If it doesn't work, I will try to provide data for producing a callibration entry.) But when I run the Lens correction module, it shows neither lens. (The exif data shown by darktable correctly identifies the lens.) What is going on? Do I just have an old version of the database. Can I correct that under Fedora 17, or do I have to install an more up to date version of Fedora? Another confusing thing: The file for nikon in /usr/share/lensfun doesn't contain an entry for the 24-70 mm lens but it does show one for the 70-200 mm lens. Yet neither shows up in darktable. Where is darktable looking for the lens correction data? Finally, note that the gimp filter GimpLensfun show exactly the same choices for lenses as darktable, so it seems they may be looking in the same place. I would like to get all this straight before going to the effort of providing calibration images, so if anyone can help me, I would appreciate it. -- Leonard Evens [email protected] Professor Emeritus, Department of Mathematics, Northwestern University ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
