Sounds like a very good plan. Is there intention to do this kind of annotation for only the raw scan, or for intermediate stages of dirt cleaning?
request the raw frame and the few around it from me, and work on doing the hard work that PFClean simply can’t handle.
Glue frames are a big perpetrator here. The glue itself is often not a big issue, unless there is major movement in that part of the frame. But it frequently throws the color and focus off for the shot and induces warping.
