The short answer is, it can't. The one advantage that you have in
digital photography is that you don't have to make the transfer linear -
you can do some pretty weird curves that would be impossible in film.=20
But, you still loose data - you can never recreate data that you didn't
get - it's a sad reality. About the only thing you can do is make it
look better to the viewer of the picture.
The other response is: if it looks better for most people, who cares? ;)
