Just tested myself.
You can see there’s (light) dust (actually oil) spots where I indicated them here:
PR correctly found them (and more I guess):
And erased them:
But when things get more complex than just a plain sky, it seemed not to be so helpful…
Same camera and same day, so all the spots are in the same place on the sensor. Here’s one where one of the spots is smack in the middle of the bridge lines:
PR was unable to detect it, even at 100% sensitivity:
I think it would be more helpful if you could also manually point out the spots, the way Capture One allows.
After my test results, I’m definitely not going to be sad if it doesn’t appear in PL10.
