No, I’ve never touched that, and my setting apparently was “off”.
I was just reading this:
https://forum.dxo.com/t/active-corrections-comment/16634/2
Why would I want to use this? I assume it’s to find a “list” of the corrections currently active in an image I’m editing? I guess it would be good to know what things I am using in a specific image, but how would this help me?
