That's "Top Shot" which is the entire frame. The feature I'm referring to would adjust multiple faces in a frame by selecting the same faces/sections from different frames to a single target frame

I swear that's what was announced, but I assume you're right because you actually know the term Top Shot, and I had no memory of that.

So your memory is probably better than mine. :)

I just remember some demo of a family shot and it automatically opening a little boys eyes by using another photo. And another auto combining of images so that you could take a lot of photos of a busy tourist place and automatically remove all the people.

Yeah there is a version of the smart fill available on Pixel phones
