So I borrowed your photo to see if I could get Cleanup to do a bit better, and I would argue I did. Instead of circling the area, I swiped vertically across the tattoo area several times, with each iteration removing a bit more. It took like 5 swipes and less than 10 seconds.
Update: Just wanted to add that ideally, we want the cleanup tool to work with just a single tap/circle/swipe gesture, but it’s nice to know there are some workarounds to get a better output with it.
For many things I find scrubbing to select works better than circling. Sometimes it is the reverse. Still a beta.
