First-person view: a hand on one side of the frame holds a vertical smartphone up to the person in front of you. Outside the phone he is fully dressed and looking up into the lens; on the screen it is the same man, same pose, same background, wearing nothing.

Put it anywhere: a subway car, a meeting, a convenience store, a dunk on the court, the bus, a courier, a security guard, the top bunk, a café, a yoga class, a couple. The screen can be plain nudity or add a twist: a seated man wearing only his socks on the screen, two men in suits pressed together in the elevator on the screen, someone kneeling under the office desk that only the phone can see. Men and women.

How to prompt: start with xrayphoneconcept,, say which side of the frame the shooter's hand holds the vertical phone and who stands outside it, then what the same person looks like on the screen. Add a separate sentence that nudity appears only on the screen and everyone in the real scene is fully dressed with nothing exposed, or the people outside the phone get undressed too. Do not list people who exist only on the screen as characters, or they will appear in the real scene. Describe each person's look, age like "an adult man aged 23", clothes and expression; it works best when the person outside the phone looks straight into the lens.
