left top branch exhibits strong purple fringing

picture taken with R, raw format, converted in DPP, also tried LR and Luminar, could not remove the purple fringing in the branches.

Modern software deals with this well, in particular, DXO PL4 works well on purple fringing (it could not do DeepPrime as the file was not raw).  I ran you picture through DXO PL4 and applied purple fringe removal. DXO PL4 also did some lens distortion correction (not sure if it should have, but it was enabled by default and it also did some sharpening/detail improvement).

I started with the Purple Fringing "automatic" settings and it suggested 100% and size=8, but I upped the size to 10 as it seemed to kill more of the purple. BTW, I would suggest punching up the saturation by about 20% (not done to the picture below) and the picture looked better IMO as it was a gray overcast day and the purple fringing did not come back.

DXO PL4 HQ mode with Purple Fringe = 100% and  size=10
