An Invert function has been requested in Lightroom Classic for more than a decade with no reponse.

I suspect that asking for it in Lightroom Classic is the wrong place since it ultimately needs to be a Camera Raw function.

Inverting the Tone Curve only partly works since tonal adjustments are reversed and many that work on colour 'see' the negative colours and therefore do not work well at all.

I would love to see a properly implemented Invert in ACR/LrC/Lr so that RAW files 'DSLR scanned' from negative film can be processed just as easily as normal positive RAW files.

Still waiting in hope.
