dho81, I think people get that it's not a permanent rating. And that there are some workflows for which this is a real time saver (see posts to date).
The point is that for some, why take the time to rate them if you have to reevaluate the ratings and rerate later, anyway? There's another concern, which is, if you rate from 1-5 in camera, how do you know which one's you've only rated on camera, and which ones you've done a final rating on after ingest?
I'm thinking that if I decide to rate on-camera, then it'll probably be a three point scale: bad = delete on the spot. unrated = maybes. 1 = the top ones to look at first.
Then, when I ingest, I can look at the 1s first and rerate. Then do the same for the unrated ones later. Ratings 2-5 are only applied after ingest, and I still get to triage a (single) group to look at first.
