Photo Booth Montage

A specific form of Photo Montage.

Some characters, usually a romantic couple, rush into a photo booth, and the audience is treated to a brief Montage of the photos they took there. The last picture must feature the characters making silly faces or mugging in some way—it's required. This is a common feature of girls' night out, too, and can usually be spotted as a small part of a greater montage.

Examples of Photo Booth Montage include:

Anime and Manga

In Mahou Sensei Negima, a bunch of the characters go to a photo booth and much Ship Tease ensues as the resultant pictures feature Negi and Asuna, Negi and Nodoka, Negi and Yue and Haruna, and Konoka and Setsuna.
In Love Hina, Keitaro has a tradition of taking photo booth pictures, but since he's such a loser, his album is full of pictures of just him, alone. Naturally he's very excited when Naru offers to take some pictures with him.

Music

In the video for Aerosmith's "Crazy", the two runaway delinquents (played by Alicia Silverstone and Liv Tyler) hop into a convenience-store photo booth to change clothes. Averted in that the audience never sees the photos, but the girls hand them off to the store clerk. His reaction to what he sees kinda makes you wish you could have seen the photos.
