This is a more artistic moment because it's in black and white. If this was in a video, Damon would appreciate the way that this was shot. She looks beautiful in the filter, even without being particularly dressed up. He loves that he can see her big genuine smile and even see her laugh. Her smile seems even more beautiful because it looks especially white in this filter, which makes it stand out even more. He wouldn't be able to help smiling too if he saw this.
