This is a continuation of other posts. I've found that darktable, at least the version I have, has some problems doing distortion control with my Nikon D800 NEF images and the 24-70 mm lens. Although it shows the exif data as seeing the camera and lens, the lens control module doesn't actually know about either the camera or the lens. (This may be a problem with the lensfun database.) What worked for my Nikon D90 with a Nikkor 18-200 mm and a Sigma 10-20 mm lens doesn't work for the new camera.
But, as best I can tell, my D800 NEF images don't seem to need much, if any, distortion correction. I think I have auto corrections set in the camera. According to Thom Hogan's book, auto correction works for NEF images only when converted by Nikon software. Is darktable doing the same thing? If that is the case, I need not worry about the matter. How does the camera do distortion correction? -- Leonard Evens [email protected] Professor Emeritus, Department of Mathematics, Northwestern University ------------------------------------------------------------------------------ Own the Future-Intel(R) Level Up Game Demo Contest 2013 Rise to greatness in Intel's independent game demo contest.
