Usagi: Cracks the biggest, cheesiest grin. It looks silly but it makes everyone laugh, including the photographer.
Ami: They all turn out perfect but rather identical.
Makoto: Super nervous in front of the camera. Can’t relax and isn’t a good enough actor to fake it, so all her photos end up with a weird, uncomfortable smile.
Minako: One of those people who does a fresh manicure, haircut, face mask and makeup routine for school photos, resulting in her looking really nice but almost entirely unrecognisable. All her school photos look like strangers. Photographer eventually gives up trying to make her not flirt at the camera.
Manga!Rei: Turns up on the day, says “Oh, was today photo day?”, sits down and gets it perfect first time.
Anime!Rei: Same as above, but secretly spends all night practicing even more than Minako.
