The camera zooms in slightly, just enough to draw attention to Norma, but not enough to reveal any details. Not exactly a camera movement, a zoom is an adjustment of the lens, changing its focal length to alter its field of view. Norma's image grows bigger, but only slightly, thereby evoking Joe's shift of attention—and failure of recognition.
