So then you just feed RealFill the 20 pictures you took and your uncle is magically painted in.
It was supposed to adjust eyes to open them if you took multiple photos.
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.
