The Princess of Wales has admitted to editing an image of her and her three children.  

The first image since her abdominal surgery, it was posted to mark Mother's Day in the UK.  

It was then pulled by numerous media photo agencies over concerns it'd been manipulated.  

Catherine says like many amateur photographers, she occasionally experiments with editing.  

Daily Mirror Royal Editor Russell Myers told Mike Hosking that he's not sure why they'd publish the photo themselves or send the photo to the world's media organisations.  

He says there's still a litany of issues: how much it was edited, how many photos it was taken from, and when it was edited.
