I'm very happy to hear that :-) The very simple "linear radial" option should come soon. And I'm also working on a "polynomial radial" option. > The algorithm takes some time, but I suspect because it happens at a > very early stage of the processing chain, caching should be very > efficient here, shouldn't it? Yes, currently the analysis phase takes some time. It can be improved, but more importantly it should be done only once, since as you mentioned it comes in at the very early stages of the processing. Darktable's general caching strategy should be improved, or maybe I haven't found yet how to use/activate it? I'm also making some progress towards moving lensfun before cacorrect. Currently I've got very good results placing it just after the temperature module, but it seems that the color scale is already non-linear and (even small) highlights are bleeding due to interpolation. AMAZE gets lost completely on the highlights. I hope I'll be able to fix that.
