The image is from a 1980 performance called Don't Smile; You're on Camera, where she trained a video camera onto a seated audience in front of her. Behind her was a video monitor apparently displaying what the camera recorded. Behind the scenes was an assistant mixing the feed so that when Hatoum trained the camera on someone's clothed chest, either an image of a naked chest appeared, a chest clad in underwear or an x-ray of lungs. At times the gender would be switched as well. Audience members left in anger.
