The actress Jennifer Lawrence was chosen to be the face of the brand "Miss Dior". So when the images of the campaign were released, the TV show Access Hollywood asked her what she think about the finish result, to which she replied "That doesn't look like me at all. I love Photoshop more than anything in the world. Of course that's Photoshop. People don't look like that."
To see what she means by that, we made a comparison between a image of Jennifer Lawrence without Photoshop (left), taken in the set of the photoshoot and the one that was released as the ad campaign(right).
As we can see, they use Photoshop to elongated her neck and make her face a more slim.
