Hi, my lens is not yet supported by lensfun. I therefore searched for a method to to get the right distortion and chromatic aberration profile to be used in daktable. (And I was not very successful applying the "manual" method using Hugin.)
However, as this is a modern lens the profiles are already integrated in the RAW file and I therefore followed this procedure: 1. convert the RAW file (NEF) to DNG using Adobe DNG Converter 2. extract OpCoodeList3 parameters from DNG file using dng-validate.exe (at the bottom) I assume I can implement these values using the lensfun distortion profile model "acm". However I'm puzzled that values are provided in several "planes". Are the planes referring to different color channels? How to implement the planes in lensfun? How can I cover chromatic aberration using these information? Thanks in advance for the insight! Sample output from dng-validate.exe -v: >>>>>>>>>>>>>>>> Opcode: WarpRectilinear, minVersion = 1.3.0.0, flags = 0 Planes: 3 Optical center: h = 0.501405 v = 0.504913 Plane 0: Radial params: 1.025498, -0.124349, 0.058447, -0.003755 Tangential params: 0.000000, 0.000000 Plane 1: Radial params: 1.025181, -0.124368, 0.058438, -0.003759 Tangential params: 0.000000, 0.000000 Plane 2: Radial params: 1.025277, -0.124355, 0.058413, -0.003751 Tangential params: 0.000000, 0.000000 <<<<<<<<<<<<<<<<<
