That will be a major problem. And what should be allowed? Nobody will object to red eye reduction. But in former times photo manipulation was something dictatorial governments did a lot (like the Russians taking persons out when the guy was persona non grata).

It is normal that magazine cover girls are manipulated these days.

A not so good but very big German newspaper some years ago manipulated a historic picture. It showed our Foreign Department minister when he was a student in a demonstration. And they made it look as if he threw a stone. In this case the old historic pic was available and had been printed often before.

I am concerned very much about these issues as I'm afraid they cannot be solved.
