Keira Knightley may not like Photoshop very much.

The 29-year-old "Imitation Game" actress explained why she deliberately bared her breasts on the Sept. 2014 cover of Interview magazine. Hollywood Life cited her interview with The Times (subscription required to view), where she spoke of being digitalized multiple times, "I've had my body manipulated so many different times for so many different reasons, whether it's paparazzi photographers or for film posters."

The said photograph belongs to a series of shots captured by Patrick Demarchelier. In their dialogue via Interview (click to see pictures), Keira mentioned about getting a piece of advice from the photographer, "You have to relax your face, because that's what good movie acting is, a relaxed face. It's the same thing as having pictures taken."

And relaxed she was. Sporting wet-looking hair, Keira flaunted her feminine form wearing a pair of pants and lace gloves -- nothing more.

Another excerpt of Keira's interview with The Times was cited by CNN, where she particularly referred to her breasts, "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."

MTV noted a part of the interview where she expressed her opinion about society's current outlook on the female body, "I think women's bodies are a battleground and photography is partly to blame... Our society is so photographic now, it becomes more difficult to see all of those different varieties of shape."

However, this isn't the first time Keira went for a topless shoot. Back in 2012, USA Today wrote that the actress also did the same thing for Allure -- only that her breasts weren't completely exposed. At the time, Keira already didn't care about going naked, "I don't mind exposing my tits because they're so small-people really aren't that interested!"

It goes to say that Keira is comfortable in her own skin -- and that size doesn't really matter at all!

Keira has appeared in "Star Wars: Episode I - The Phantom Menace," "Bend It Like Beckham," "Pirates of the Caribbean: The Curse of the Black Pearl," "Pride and Prejudice," "Pirates of the Caribbean: Dead Man's Chest," "Atonement," "Pirates of the Caribbean: At Worlds End," "The Duchess," "Never Let Me Go," "Stars In Shorts" and "Anna Karenina," as listed by Rotten Tomatoes.
