In PSP Photo Kano, you are a high school who recently got a camera. By building relationships with girls, you can take photos of them in a variety of different situation, including inevitable skimpy pics.
Photo Kano is kind of like Pokémon Snap, but not as cute and with bigger tits. So I guess it's really not that much like Pokémon Snap, save for the picture taking.
Watch the game's six minute trailer to see it in action. Six minutes, folks, six minutes.
