No don’t!!! They are more important and more useful than writing stuff to the RAW file. Rather switch off writing to the RAW files.
PL only uses XMP files for writing to. It never writes to the RAW file (as I previously explained - please take the time to read my post on the subject). It only reads from the RAW file if there is no XMP sidecar, but then it creates and writes everything back to the XMP.
Correction. Due to a change in their licensing https://home.camerabits.com, you now only own PM as long as you don’t upgrade the operating system. Then it switches to rental.
No problem. I’ll even give you a hands on tutorial via screen sharing if you want? it really is a lot simpler than anything else you’ve ever used.
