spoiler comment - - - - For those confused by the thought that eyes can move in a single photo: In the olden days, photos were taken over several seconds or even minutes, and the subjects had to stay perfectly still to avoid blurring the photo. So in the story, her eyes must have been a blur. If the story were written today, he would have taken 200 pictures on his phone, and eventually noticed that her eyes had moved between one photo and another.
