How you remove the grain or texture like this photo with #gimp 2.10? i remember there was a plugin but forgot the name. Help please? i don't own the photo, is an example. I used time ago FFT technique. @GIMP_Official Thanks

Maybe @patdavid ?with his knowledge about photo retouch? i am a bit lost. btw median filter works pretty fine. thanks @gimp team.

After using @gmic_ip very good. i need to explore more but is nice. Why are the edges with this kind of pattern in the left side and the right side? :O
