The BBC says "Photo tool could fix bad images" but I think it's far more likely to be used to create fake images. I guess I wouldn't have thought of an image that shows what was actually present as 'bad' – maybe it's not the best postcard if you want the recipient to think you were in an undeveloped paradise, but it's an accurate depiction of the scene.
I'm reminded of the way the Soviets would remove people from historic photos when they fell out of favour – now the ability to rewrite history is available for you at home!
