Only one of the photo editors I have on my Mac (Dxo's PhotoLab) actually seems to do automatic lens corrections. Several of the others say that they do, but either require manual correction or do not handle my Olympus 8mm FE properly. Because of that I decided to look into LensFun with the idea of using it as a plugin for some of my pixel editors. When I visited the LensFun website all that they seemed to have was a source download and some 'makefiles' to create the tool on my system, but no real information on how to use it. I thought there might be some information about that on this forum, but a search did not show me anything that answered my questions and I decided to ask specific questions. Perhaps someone has looked into this and can tell me. 1) Does the LensFun make produce a usable stand-alone tool? Either a console app or a GUI? 2) If so, can it be called as a plugin from a pixel editor? 3) If not, what does the make give you? Perhaps I can build a 'swift' wrapper around it. 4) And, perhaps most important, is there a downloaded version of LensFun that is already built? I am not sure I have the proper libraries on my system to build it, and am not sure I want to install what I might need. Thank you for any information you can give me.
