DELETE A BACKGROUND? EASY. SMOOTH OUT A FACE? SEAMLESS. DIGITAL PHOTO MANIPULATION IS NOW MAINSTREAM

It’s been a common refrain when seeking proof that someone’s story or some event actually took place: “Pics, or it didn’t happen.”

But in a world where the spread of technology makes photo manipulation as easy as a tap on your phone, the idea that a visual image is an absolute truth is as outdated as the daguerreotype. And a photo can sometimes raise as many questions as it was meant to answer.

That was seen in recent days when controversy descended upon an image of Kate, Princess of Wales, and her three children. News agencies including The Associated Press published, then retracted, the image given out by Buckingham Palace over concerns it had been manipulated, leading to Kate saying on social media that she occasionally “experimented” with photo editing.

In that, she’s hardly alone.

From something that was time-consuming and required a great deal of technical expertise in the days of actual film and darkrooms, digital editing has become something practically anyone can do, from adding filters to cropping images and much more. Apps abound, offering the easiest of experiences in creating and retouching photos and videos which can then be easily transmitted online and through social media.

“Cover blemishes and let the real you shine through,” says an ad for the smartphone app Facetune. “Remove and change backgrounds instantly,” the Fotor app’s website enthuses. “Our AI object remover is ready to assist you in getting rid of unwanted objects.”

This Wild West of image-altering abilities is opening new frontiers for everyday people — and creating headaches for those who expect photos to be a documentary representation of reality.
