Yes, Kate Middleton’s photo was doctored. But so are a lot of images we see today

Rumours and conspiracies have been swirling following the abdominal surgery and long recovery period of Catherine, Princess of Wales, earlier this year. They intensified on Monday when Kensington Palace released a photo of the princess with her three children.

The photo had clear signs of tampering, and international wire services withdrew the image amid concerns around manipulation. The princess later apologised for any confusion and said she had “experimented with editing” as many amateur photographers do.

Image editing is extremely common these days, and not all of it is for nefarious purposes. However, in an age of rampant misinformation, how can we stay vigilant around suspicious images?

What happened with the royal photo?

A close look reveals at least eight inconsistencies with the image.

Two of these relate to unnatural blur. Catherine’s right hand is unnaturally blurred, even though her left hand is sharp and at the same distance from the camera. The left side of Catherine’s hair is also unnaturally blurred, while the right side of her hair is sharp.

These types of edits are usually made with a blur tool that softens pixels. It is often used to make the background of an image less distracting or to smooth rough patches of texture.

Five of the edits appear to use the “clone stamp” tool. This is a Photoshop tool that takes part of the same or a different image and “stamps” it onto another part.

You can see this with the repeated pattern on Louis’s (on the left) sweater and the tile on the ground. You can also see it with the step behind Louis’s legs and on Charlotte’s hair and sleeve. The zipper on Catherine’s jacket also doesn’t line up.

The most charitable interpretation is that the princess was trying to remove distracting or unflattering elements. But the artefacts could also point to multiple images being blended together.
