Take a photo with a three-layer Polaroid camera.
The photo should look like a regular photo, with no visible subject or props. There should be a steady light source, like a flash in a dark room, distributed throughout the photo. The first photo shows the couple smiling at the camera. The second photo shows the girl with her eyes wide open, like an attractive girl, pointing at the boy while the boy smiles and looks at her affectionately. The third photo shows the girl's head on the boy's shoulders while the girl has her eyes closed and the boy looks at the girl.
