I've read about "adaptive optics" as used by the US military, intelligence agencies, etc in satellite imagery, but what about using optics to correct out of focus pictures? Is this possible?
Suppose you've taken a photo that is blurred (not due to
movement, but due to improper focus).
Would it be possible, if you could look through just the right
type of lens, to see the picture correctly focused?
If so, would it be possible for software to calculate the
focus problem, or even for a photographer to just go through
progressively different foci to fix something that is blurred?
