Are you referring to the 'worms'? https://www.exploringexposure.com …pening-fujifilm-raw-files
I have this with my X100T in Lightroom, I believe it's has improved over the years, and I only get it on foliage. My most recent photos of the heather and trees showed a huge amount of it. I haven't tried other editing software as it's doesn't effect me enough to warrant it, but Capture One etc. don't seem to have this issue.
Which sensor do you have? There's Lightroom sharpening settings that can mitigate the worms.
Thanks for the link.. that could be it.. although its not just in foiliage .. even straight edges take on a weird look..
Ill post a sample photo after work.. ill also try the suggested setting in that link
Xt2 is what im using
