Keira Knightley is hardly the first star to be vocal about her dismay at being photoshopped — but she is one of the first to respond so visibly. The star posed topless for famed photographer Patrick Demarchelier in Interview magazine, and as she tells the Times of London, she had a very good reason for doing so.

“I’ve had my body manipulated so many times for so many different reasons, whether it’s paparazzi photographers or for film posters. And that [shoot] was one of the ones where I said, ‘OK, I’m fine doing the topless shot so long as you don’t make them any bigger or retouch.’ Because it does feel important to say, It really doesn’t matter what shape you are.”

She went on, “I think women’s bodies are a battleground and photography is partly to blame. It’s much easier to take a picture of somebody without a shape; it simply is. Whereas you need tremendous skill to be able to get a woman’s shape and make it look like it does in life, which is always beautiful.”

Knightley also addresses the difficulty women face as far as aging goes. “It’s really desperate, the image we have of women, and when women became invisible or when you hear someone say, ‘She’s let herself go,’ whatever the f— that means. What — because she’s got grey hair? I do think it’s something that needs to be addressed.”
